Mitsubishi MVB42FCBMC-L Rotary Compressor: R32 Technical Data, Inverter Performance and Selection Guide

The Mitsubishi MVB42FCBMC-L is a hermetic inverter-driven rotary compressor rated at 42.1 cm3/rev displacement, 14,380 W of capacity, 4,400 W of input and a coefficient of performance of 3.27 on refrigerant R32. It is manufactured by Mitsubishi Electric (Guangzhou) Compressor Co., Ltd.

What is the Mitsubishi MVB42FCBMC-L?

It is one of the larger inverter rotary compressors in this site's Mitsubishi rotary compressor range, and it is the top row of the R32 ladder the site publishes at this displacement band. Nothing in the printed figures for this part number is unusual for a modern single-cylinder inverter rotary compressor: 42.1 cm3/rev of swept volume, a rated capacity of 14,380 W, a rated input of 4,400 W and a coefficient of performance of 3.27 on R32. What makes the model worth a guide of its own is not its headline number but the two independent documents that carry it. The manufacturer's own model page prints the specification table, and a third-party testing house printed the same capacity figure, on a compressor identified by type, inside a technical report issued through a certification body.

That second document is why the numbers in this guide can be traced further than usual. The compressor is not merely described on a distributor page; it appears by type designation in the identification appendix of an EN 14825 test report, on a named heat pump unit, with the manufacturer and factory named on the same page. A capacity figure that a test house printed is a different class of evidence from a capacity figure that a sales page printed, and this guide keeps the two separate throughout rather than blending them into one specification table.

The table below collects the published figures for this part number. Each row names where the figure comes from, because a compressor data sheet is only as useful as its traceability.

Two entries in this table deserve a note before they are used. The dimension field is printed as 350A/mm with no unit key on the site, so this guide reports the string as printed rather than translating it into a height, a diameter or a mounting footprint, none of which the page states. And the application field is a list of equipment classes rather than a rating: it records what a compressor of this size can be built into, not a published capacity at any of those conditions.

The density figures, 341.6 W and 104.5 W per cm3/rev, are derived here rather than published. They are included because comparing compressors of different displacement is otherwise impossible. They must not be quoted as manufacturer ratings.

Technical specifications and what each number is based on

A specification table in a selection guide has one job beyond listing values: it has to make clear which values are measured, which are printed and which are computed. The table below separates those cases for every figure this guide uses.

The arithmetic check matters more than it might appear, and this row is where the site's own page has something to disclose. A product page that prints a metric capacity, an imperial capacity, an input and a coefficient of performance is printing four numbers that are not independent: the coefficient is the capacity divided by the input, and the imperial figure is the metric figure converted at 3.412 Btu per watt-hour. On this row the coefficient holds exactly, because 14,380 divided by 4,400 is 3.2682 and that rounds to the printed 3.27. The imperial figure does not hold. The printed 48,892 Btu/h is 172.56 Btu/h below the strict conversion of 49,064.56 Btu/h, which is a shortfall of 0.35 percent.

The direction and the size of that shortfall point at a cause rather than at rounding. Dividing the printed imperial value by the printed metric value returns exactly 3.400000, and multiplying 14,380 by 3.4 returns exactly 48,892, so the page converted this row at a factor of 3.4 rather than at 3.412. On its own that would be a house convention, and a reader would have no basis to call it an error. It is not on its own. The same site publishes an R410A row at the identical displacement, MNB42FCBMC, and that row converts at 3.412 exactly: 13,780 multiplied by 3.412 is 47,017.36, which the page prints as 47,017. One site, one template, two conversion factors, and the factor that is wrong appears only on the R32 rows. This guide therefore reports the printed imperial figure as printed, reports the strict conversion beside it, and treats the difference as a defect in the source rather than as a property of the compressor. For any calculation, use 14,380 W and convert it yourself.

How to read the MVB42FCBMC-L model number

No naming legend covering this series was located in the documents reviewed, so this section is written differently from the model-number sections of some other guides on this site. There is no published key to check the string against. What there is instead is a set of nine model strings captured from the same site, two of which sit at the same displacement on different refrigerants, and those pairs make some segments readable by comparison even though none of them is documented.

Two segments in this string are readable enough to be useful, and the limit on both should be stated in the same breath. The displacement block returns the integer part of the printed displacement across the three displacements captured, which is a pattern rather than a rule, and it is a pattern observed on nine rows that all come from one site's template. The second character separates the two refrigerants in the captured set, and it separates them cleanly, with V on R32 rows and N on R410A rows at an identical displacement and an identical dimension field. That is a real signal, and it is two data points deep at the displacement this guide covers.

The reason no legend could be checked is itself a finding, and it belongs in this section rather than buried in the notes. The manufacturer's own product site does publish a set of series prefixes for its rotary compressor lines, and the prefixes it lists are KHB, SHB, THB and LHB, KHV, SHV, RHV and THV, KNB, SNB, TNB and LNB, and REV and TEV. None of them is the MVB or the MNB prefix. The same site lists refrigerant families of R22, R410A, R407C and R134a, and it does not list an R32 family at all, which is consistent with the model pages for this compressor being published by a distributor rather than by the manufacturer directly. The manufacturer's product information is reachable through its own inverter compressor product page, and this guide reports what that page does and does not contain rather than inferring a naming system from it.

Where the MVB42FCBMC-L sits in the R32 ladder

The most useful comparison for this part number is the three-row R32 ladder the same site publishes, because a product planner choosing between them is choosing between displacements rather than between unrelated parts. The three rows are printed with the same refrigerant, the same capacity convention and the same field structure, which makes the differences between them meaningful in a way that a cross-brand comparison is not.

Every row in this table is a site-published row, and every row has been checked against its own internal arithmetic before being listed. The three 42.1 cm3/rev rows reproduce identically across all five numeric fields, which is what a family entry looks like when the manufacturer fits one compressor into three different system configurations rather than building three compressors. The three 33.8 cm3/rev rows reproduce identically for the same reason.

The step between displacements is where the selection decision lives, and the step in this ladder is not the same shape as the one on many other ranges. Capacity grows faster than swept volume, and input grows more slowly than capacity.

Two things follow from those figures, and they point in opposite directions for a buyer. The first is that stepping up this ladder is not an efficiency penalty, which is the more common outcome on a range built around a fixed envelope. Twenty-four and six tenths percent more swept volume buys twenty-six and five tenths percent more capacity for twenty-three and three tenths percent more input, so the coefficient of performance rises by two and eight tenths percent across the full step and by one and six tenths percent across the smaller one. Capacity per unit of swept volume rises from 336.4 to 341.6 W per cm3/rev and input per unit of swept volume falls from 105.6 to 104.5 W per cm3/rev, so the larger compressor is doing more work per cubic centimetre swept and using less energy to sweep it. That is a better machine rather than merely a bigger one.

The second is that the ladder is not a single chassis. The dimension field moves from 310.3A/mm on the two smaller rows to 350A/mm on this one, and it does so at the point where the displacement step is largest. A platform that has been built around the smaller envelope therefore cannot take this compressor as a drop-in substitution, and the step up has to be checked against the drawing rather than assumed from the fact that the three rows share a family name and a refrigerant. This site carries additional Mitsubishi R32 records in the same address family, including the MVB40FJLMC-LS, the MVB40FKLMC-LS and the MVB40FJLMC-L, and those rows are named here because a reader comparing displacements will encounter them; they did not return a specification table when retrieved for this guide, so no value from them is used anywhere in it. The site also publishes model guides of its own for other Mitsubishi compressors, among them the Mitsubishi MNK42FDMMC-L guide, and those are separate model records rather than variations of this one.

There is one further limit on reading a ladder as a range. A ladder of rated points shows where a manufacturer has placed its published ratings, not how any two compressors behave across the whole operating map. Two rows at different displacements with different rated points are evidence that the manufacturer characterised the two differently, and a selection should be made against the part-load conditions the system will actually see. The catalogue point is enough to shortlist a row. It is not enough to award one.

How does R32 compare with R410A at the same displacement?

This site publishes both refrigerants at an identical swept volume, which is unusual and which makes the comparison worth stating as a table rather than in prose. MVB42FCBMC-LS is the R32 row; MNB42FCBMC is the R410A row, and the two sit at the same 42.1 cm3/rev and the same 350A/mm dimension field.

The first line of the table is the one a buyer is most likely to misread, and the disclosure from the conversion note applies to it directly. Comparing the two imperial figures as printed shows a 3.99 percent capacity advantage for the R32 row, which understates the true gap, because the R32 row was converted at 3.4 and the R410A row at 3.412. Converting both at 3.412 shows the gap as 4.36 percent, which is consistent with the 4.35 percent the metric column shows. The mixed convention inside one site template distorts the cross-refrigerant comparison as well as the single-row conversion, and it does so in the direction that makes R32 look marginally less attractive than it is.

What the table establishes about the two refrigerants is narrower than the table's rows might suggest, and the narrower reading is the correct one. At a fixed swept volume, this pair shows the R32 variant delivering about four and four tenths percent more capacity for about eight and nine tenths percent more input, which is a coefficient of performance about four and one tenths percent lower. That is a property of this pair of rated points as published, not a general law about the two refrigerants, because a manufacturer is free to place the rated points of two platforms differently. The useful reading is that a buyer who needs the lowest published input at this displacement has an R410A row on the same page, and a buyer who needs the highest published capacity at this displacement has the R32 row.

The entries in that table that come from published sources are the composition, which is the blend ratio carried by the refrigerant designation standard named in the standards table below, the safety classification, and the global warming potentials of the two refrigerants, and every one of those sources is registered at the end of this guide. The design pressure ordering follows from the refrigerants' own properties rather than from any compressor figure. What the compressor data does establish is where the responsibility sits: because the site publishes both refrigerants in the same envelope and at the same displacement, the compressor is not the component that decides the refrigerant, the system is. A buyer replacing a compressor inside an existing R410A unit must replace it with an R410A unit, because the oil and the metering device in that system were selected for a blend at a given pressure. A buyer designing a new platform can choose either, and the choice then propagates into the charge limit, the leak detection and the siting of electrical components.

The European prohibition schedule is the other half of that decision, and what matters in it is whether a substance clears a threshold rather than what the dates are. R32 has a 100 year global warming potential of 675, which sits below the 750 threshold applied to single split air conditioning with a charge under 3 kg from January 2025 and above every 150 threshold in the schedule. Those 150 thresholds arrive for self-contained air conditioning and heat pumps and for split air-to-water systems in 2027, for split air-to-air equipment up to 12 kW in 2029, for larger split systems in 2033, and as a prohibition on any fluorinated greenhouse gas in split systems up to 12 kW in 2035. The values in that sentence are drawn from the annexes of Regulation (EU) 2024/573, and the German Environment Agency publishes a global warming potential table keyed to the same regulation for reference values across substances. The same table prints the 100 year global warming potential of R410A as 2,088 on the same convention, so the substance this site publishes at an identical displacement carries a value just over three times that of R32. The consequence for the schedule above is direct: R32 clears the 750 threshold that applies to single split air conditioning from January 2025, and R410A clears none of the thresholds in it.

One boundary belongs in the same paragraph. This guide describes where R32 stands as a substance. It does not state that any particular appliance complies with anything, and no certificate held by this compressor is claimed here. A2L is a classification that places obligations on the finished product, and the completed unit is assessed against the product-level safety standard rather than against the compressor standard alone.

What has been measured with this compressor in a complete system?

The strongest document available for this part number is not a compressor data sheet at all. It is an EN 14825 technical report, issued through a certification body, in which a heat pump manufacturer identifies the compressor fitted to each of its units by type. That is where a capacity figure stops being a sales figure and becomes a tested one, and it is also where the evidence stops short of what a buyer might hope for, because the report tests units and identifies compressors rather than testing compressors.

The report is project number 64.181.20.05244.01, revision 00, dated 3 December 2020, running to 33 pages. It was issued by TUV SUD Certification and Testing (China) Co., Ltd. Guangzhou Branch, with a named test engineer and a named designated reviewer on the signature page, and the energy testing was carried out by a separate named laboratory. Its stated test specification is EN 14825:2018 with Regulation (EU) No 813/2013. The product it covers is a DC inverter air-to-water heat pump, and the report covers eight unit model designations built on four capacities. Each unit's compressor is identified in an appendix by manufacturer and type.

The last row is the one this guide is about, and it does three things at once. It identifies the compressor fitted to that unit as type MVB42FCBMC-L, manufactured by Mitsubishi Electric (Guangzhou) Compressor Co., Ltd., on refrigerant R32. It prints a rated capacity for that compressor of 14,380 W, which is the same figure the site's own product page prints, reached by an entirely independent route. And it names the manufacturer, which is the only place in the sources reviewed here where a manufacturer is named for this part number rather than inferred from the model prefix.

Two of the other rows in that table are worth a moment, because they do the same thing for neighbouring parts. The 11,370 W printed for the compressor in unit GT-SKR040KBDC-M32 is the figure the site publishes for its 33.8 cm3/rev R32 rows, which is a second independent agreement between the two documents at a different displacement. And the compressor identified for unit GT-SKR020KBDC-M32, SVB172FNPMC, carries the same series letter pattern as this model, which is part of what makes the second-character observation in the model-number section above defensible as a pattern rather than as a coincidence.

What the report does not provide should be stated as plainly as what it does, because a tested system figure is easy to misattribute to a compressor. The report's headline results belong to the units it tested. Unit GT-SKR050KBDC-M32, the one fitted with this compressor, carries a design heating load of 15.752 kW, a seasonal coefficient of performance of 4.67, and an annual heating demand of 32,544 kWh. Those are whole-system results at a defined climate and load profile, and they include the compressor, the heat exchangers, the fan, the pump, the controls and the defrost strategy. They are not properties of the compressor, and this guide does not present them as such. What they do establish is a realistic operating position: the compressor's rated capacity of 14,380 W is about 91 percent of the design heating load of the unit it is fitted in, which is a sensible way to size a modulated compressor into a heat pump and is consistent with the unit being able to meet its design point with the compressor working near the top of its range rather than past it.

One constraint on the use of that report has to be disclosed wherever it is cited, and it appears on the report's own front page. The report states that any use for advertising purposes must be granted in writing and that the technical report may only be quoted in full. This guide therefore reports the compressor identification and the aggregate results above, and it deliberately does not reproduce the report's test tables, which include the part-load matrix behind the seasonal result. A reader who needs that matrix, or who needs to rely on the report rather than to trace a figure through it, should obtain the report in full and use it in full, and should approach the issuing body and the client named on it about any use beyond reading. The report is hosted by a distributor rather than by the manufacturer or the testing house, and that hosting arrangement is disclosed here so that the link is not mistaken for an official manufacturer address.

Which applications suit the MVB42FCBMC-L?

The first thing to settle is what the published data actually supports, because the rating convention decides the answer.

• Air-to-water heat pumps and other inverter-driven heating equipment. This is the application the strongest available document covers. The compressor is identified on a DC inverter air-to-water heat pump in a report issued through a certification body, tested to the EN 14825 seasonal efficiency specification, and its rated capacity sits at about 91 percent of that unit's design heating load. A designer working in this segment has a tested reference point rather than only a catalogue row.
• Residential and light commercial air conditioning where R32 is the chosen refrigerant. At 42.1 cm3/rev with 14,380 W of published capacity, this is a compressor for a single split, a small multi-split or a small packaged unit rather than for a large central plant, and it is on the R32 side of the refrigerant decision rather than the R410A side.
• Platforms already committed to the R32 ladder at this site. The three 42.1 cm3/rev rows reproduce identically, so a platform built around one of them can be re-sourced across the other two without a specification change, which matters more in procurement than in design.
• Systems whose part-load behaviour matters more than the rated point. An inverter compressor's value in a heat pump is the ability to follow the load rather than to cycle, and the seasonal result printed for the unit this compressor is fitted in is the evidence that the combination does so.
• Builds where the printed capacity has to be traceable. A capacity figure that appears in both a manufacturer-side identification and a product page is easier to defend in a specification than a figure that appears in one place, and this model is one of the few on this site where that is true.
• Platforms that need to choose between refrigerants on compliance grounds. Because the same site publishes an R410A row at the same displacement and the same dimension field, the refrigerant choice can be made on the compliance position rather than on compressor availability. The refrigerant families the manufacturer lists on its own site do not include R32 at all, which is worth knowing before planning a platform around it.
• Not for a duty point that depends on a refrigeration or freezing rating condition. The published rating for this row carries a capacity figure with no printed condition label on the product page, and the application list on that page names air conditioning, driers, refrigeration and chillers as a single undifferentiated list. Whatever that list says, no capacity at an evaporating condition is published for this part number in the documents reviewed, and the 14,380 W figure should not be read as one. A low-temperature or refrigeration selection has to be made from a source that publishes a capacity at that condition.

That exclusion is not a technicality. The application list on the product page is a list of equipment classes a compressor of this size can be built into, and it is printed identically on every R32 row at this displacement. It carries no condition and no capacity, which means it cannot be used to size anything. The one capacity figure available for this part number is a rated capacity that the site prints without a condition label and that a third-party report prints for a compressor fitted into a heat pump, and both of those are heating and cooling duty points rather than refrigeration duty points. A buyer who needs this displacement for a refrigeration duty is not unserved by the manufacturer, but they are unserved by these documents, and they should say so when they ask for a rating.

Which standards apply to a compressor like this?

Pointing at a standard is not a claim that this compressor has been assessed against it, and no certificate held by this compressor is claimed anywhere in this guide. The compressor standard covers the compressor as a component. The appliance standards cover the finished product, and it is the finished product that carries the refrigerant charge and therefore the refrigerant safety obligations and the A2L measures. The seasonal efficiency specification is a measurement convention rather than a safety requirement, which is why a compressor can appear in a report under it without the compressor itself carrying that rating. The EN 14825 specification is named here by number and regulation reference because it is the specification printed on the report this guide cites, and the ISO entry is named by number rather than linked because the standard catalogue pages could not be retrieved programmatically during the preparation of this guide. The refrigerant designation standard is linked, because its catalogue page is reachable, and it is the source of the blend composition printed in the comparison table.

The certification body that issued the report is named on the report itself and is not linked here, because the body's public site did not respond to the requests made during the preparation of this guide in a way that would support a stable link. The issuing chain on the report is a testing and certification company acting through its Guangzhou branch, with a named engineer and a named designated reviewer, and the energy testing carried out by a separate named laboratory. A reader who needs to verify the report should quote its project number and revision to the client named on it, which is the manufacturer of the heat pump rather than the manufacturer of the compressor. That distinction is the most important thing in this section: the report is evidence about a compressor as fitted and tested inside somebody else's product, and it is not a certificate for the compressor on its own.

Selection checklist

1. Confirm the refrigerant the system will use. This site publishes the same displacement on R32 and on R410A in the same dimension field, so the choice is a compliance and servicing decision rather than an availability one. Settle it before ordering, and check the refrigerant against the schedule of the market the product will be sold in.
2. Read the displacement from the model page, not from the string. The two-digit block in the string does return the integer part of the printed displacement across the three displacements captured, but that is an observed pattern rather than a published rule. Size from the printed row.
3. Treat the printed imperial capacity as a rounded artefact and do your own conversion. The page converted this row at 3.4 rather than 3.412, which puts the printed imperial figure 172.56 Btu/h low. Use the metric values in any calculation.
4. Decide which end of the ladder you are buying. Across the full 33.8 to 42.1 cm3/rev step, capacity rises by 26.47 percent and input by 23.25 percent, so the step up is not an efficiency penalty here. Take the smallest row that meets the load.
5. Check the envelope before assuming interchangeability. The dimension field changes from 310.3A/mm to 350A/mm between the 36.7 cm3/rev row and this one. A cabinet, mounting or pipe layout sized for the smaller row has to be re-checked, and the drawing is the authority rather than the family name.
6. Establish the modulation requirement before the rated point. An inverter compressor is bought for its part-load behaviour. Ask for the performance map over the conditions the system will see, and use the catalogue point only to shortlist.
7. Ask for the figures this page does not print. Mass, oil charge, running speed, locked rotor current, sound power level and shell diameter are all absent for this part number in the documents reviewed. A design that needs any of them needs them from the supplier.
8. Confirm the drive arrangement from the drawing. The site states the drive in a field labelled for voltage, which is a template defect rather than data. Confirm the inverter drive, the electrical supply and the control interface from the drawing or the data sheet for the specific part.
9. Fix the compliance position for the refrigerant. R32 carries a global warming potential of 675 and an A2L classification. The thresholds and dates in the refrigerant section above should be checked against the market and the charge size.
10. Ask for the current document and the tested evidence together. The specification figures here come from a product page, and the capacity corroboration comes from a 2020 technical report on somebody else's product. Ratings are revised, and a compressor selected on a superseded table is a project risk rather than a sourcing saving.

Frequently asked questions

Is the MVB42FCBMC-L an inverter compressor or a fixed-speed compressor?

The available evidence says inverter, and it comes from the site's own page rather than from a naming legend. The page carries the word INVERTER in its specification block, in a field labelled for voltage, where the value printed is INVERTER Compressor rather than a supply voltage. That is a template defect, because a drive description is printed where a voltage belongs, but the drive class it states is consistent with the page title and with the family the model sits in. No manufacturer naming legend covering this series was located during the preparation of this guide, so the drive class is reported from the page rather than decoded from the string. A buyer should confirm the drive arrangement from the drawing before ordering.

What is the difference between the MVB42FCBMC-LS and the MVB42FCBMC-L?

They are the same compressor under two designations. The site addresses this model as MVB42FCBMC-LS, and the technical report in which the compressor is identified by type prints the manufacturer-side designation MVB42FCBMC-L, without the trailing S. Every printed figure available for the two designations agrees, including the displacement of 42.1 cm3/rev, the capacity of 14,380 W, the input of 4,400 W, the refrigerant R32 and the dimension field of 350A/mm. This guide treats the difference as a designation difference between a distributor's catalogue and a manufacturer's identification, not as a difference between two compressors, and it does not assign a meaning to the trailing character.

What is the difference between the MVB42FCBMC-LS and the MVB42FCPMC?

Within the evidence available they are the same compressor. The site publishes both at 42.1 cm3/rev, 14,380 W, 48,892 Btu/h, 4,400 W, a coefficient of performance of 3.27, a 350A/mm dimension field and refrigerant R32, and every numeric field reproduces identically. The two differ in the middle of the model string and in the suffix, and no published legend covering this series was located, so this guide reports the two as identical rows in the site's own table and does not speculate about what the internal characters denote. A buyer comparing them should treat them as one selection and confirm which is available.

What is the difference between the MVB42FCBMC-LS and the MNB42FCBMC?

They are the same swept volume on two different refrigerants, and the site publishes them side by side. Both are 42.1 cm3/rev and both carry a 350A/mm dimension field. The R32 row prints 14,380 W for 4,400 W of input and a coefficient of performance of 3.27, and the R410A row prints 13,780 W for 4,040 W and a coefficient of performance of 3.41. The R32 row therefore offers about four and four tenths percent more capacity for about eight and nine tenths percent more input. The second character of the string differs between the two, with V on the R32 rows captured and N on the R410A rows, and the remaining characters in these two strings are identical.

Why is the printed imperial capacity lower than the metric capacity converted at 3.412?

Because the page converted this row at 3.4 rather than 3.412. The printed metric capacity is 14,380 W, so a strict conversion gives 49,064.56 Btu/h, while the page prints 48,892 Btu/h, a shortfall of 172.56 Btu/h or 0.35 percent. The printed imperial figure divided by the printed metric figure returns exactly 3.400000, which is what identifies the factor used. The same site applies 3.412 exactly on its R410A row at the identical displacement, so the 3.4 factor appears only on the R32 rows and is reported here as a defect in the source rather than as a convention. Nothing else on the row is affected: the coefficient of performance of 3.27 holds exactly against the metric capacity and the input.

Has this compressor been tested in a complete system?

It is identified in a technical report on a complete system rather than tested on its own. The report covers a DC inverter air-to-water heat pump under EN 14825:2018 with Regulation (EU) No 813/2013, and its identification appendix names this compressor type as the one fitted to one of the unit designations covered. The unit it is fitted to prints a design heating load of 15.752 kW, a seasonal coefficient of performance of 4.67 and an annual heating demand of 32,544 kWh. Those results belong to the unit, which includes the heat exchangers, the fan, the pump, the controls and the defrost strategy, and they are not properties of the compressor. The report also carries a notice stating that it may only be quoted in full, which is why this guide reports the identification and the aggregate results and does not reproduce its test tables.

Is there a larger or smaller Mitsubishi R32 rotary compressor available at this site?

There are smaller rows and related rows. The R32 ladder published at this site runs from 33.8 cm3/rev at 11,370 W through 36.7 cm3/rev at 12,400 W to this row at 42.1 cm3/rev and 14,380 W, and the site carries a further pair of Mitsubishi records at the 40 displacement band, the MVB40FJLMC-LS, the MVB40FKLMC-LS and the MVB40FJLMC-L, which did not return a specification table when retrieved for this guide and from which no value is used here. The report cited above identifies three further compressor types in the same series on smaller units, SVB172FNPMC, SVB220FLGMC-L and MVB33FBBMC, and this site carries a page for the smallest of those, the SVB172FNPMC R32 inverter compressor. Beyond the rows in this ladder, the site also keeps its own guide to the KH134VFLP rotary compressor, which is a separate Mitsubishi model record and carries no figure used in this guide.

Does this compressor carry a certificate for any particular market?

No certificate held by this compressor is claimed in this guide, and none was sighted during its preparation. The report cited above was issued through a testing and certification body, but it is a technical report on a heat pump unit, and the compressor appears in it as an identified component of that unit rather than as a separately certified article. The standards named in the standards section are the frameworks a compressor and the appliance built around it are assessed against, and naming a framework is not a certification claim. Market entry documentation should be requested from the supplier for the specific market and application.

Sources and verification notes

The figures in this guide come from the two primary documents below. Displacement, capacity, input power, coefficient of performance, refrigerant and the dimension field for this model are taken from one specification block on the site's product page for this part number. The manufacturer attribution, the manufacturer-side type designation and the corroborating capacity figure are taken from the identification appendix of a third-party technical report, and that report's system results are reported as system results.

• The manufacturer's own product information, as published by the compressor manufacturer in Guangzhou: inverter compressor product page. This guide reports that the page does not list an R32 family and does not use the MVB prefix, and it uses no figure from it.
• The parent brand's compressor product pages, for the product context a reader may want: Mitsubishi Electric air conditioning compressor products and the European compressor information page.
• The third-party technical report in which this compressor type is identified, hosted by a distributor rather than by the manufacturer or the testing house: EN 14825 technical report. The report itself states that any use for advertising purposes must be granted in writing and that it may only be quoted in full.
• A distributor-held listing for the same model, registered as a second read on the model's existence and designation and used for no figure in this guide: distributor listing for MVB42FCBMC-L.
• Standards and certification bodies, for the two levels of the standards framework and the refrigerant designation framework: IEC 60335-2-34:2024, IEC 60335-2-89:2019 and ANSI/ASHRAE Standard 34. The ISO and EN entries named in the standards table are cited by number rather than linked, and the certification body named on the report is cited by name rather than linked.
• Regulation and reference values for the refrigerant position and the prohibition dates: Regulation (EU) 2024/573 and the German Environment Agency's global warming potential table.
• Independent industry and research material on how seasonal performance is measured and how standards for heat pumps and refrigerants interact: REHVA Journal, heat pumps and the standards, Eurovent on understanding SEER and SCOP and the International Energy Agency's report The Future of Cooling.
• Site structure and related model pages referenced in the comparison tables: the Mitsubishi rotary compressor range, the rotary compressor category, the brand page and the individual model pages linked in the ladder and refrigerant comparison tables. Two further Mitsubishi model guides on the same site are named for completeness, and no figure is taken from either: the MNK42FDMMC-L conditioning refrigeration compressor and the KH134VFLP rotary compressor.

Six points about evidence limits belong here. First, the site's product page for this model converted its imperial capacity at 3.4 rather than 3.412, which places the printed imperial value 172.56 Btu/h or 0.35 percent below a strict conversion, while the metric capacity, the input and the coefficient of performance on the same row all hold; the printed imperial figure is reported as printed and never used in a comparison without conversion. Second, the site prints a drive description in a field labelled for voltage, so the supply is not published for this model in the documents reviewed and no supply voltage is quoted anywhere in this guide. Third, the report cited above carries a notice restricting quotation to the full document, so this guide reports only the compressor identification and the aggregate results, and it does not reproduce the report's test tables; a reader relying on the report should obtain and use it in full. Fourth, the system results of 15.752 kW, 4.67 and 32,544 kWh belong to the heat pump unit in which the compressor was tested and not to the compressor, and they are labelled as system results at every point where they appear. Fifth, no published naming legend covering the MVB or MNB series was located, so the model string is presented as an observed pattern across the captured rows rather than as a decoded key, and two segments of it are reported as undecoded. Sixth, no mass, oil charge, running speed, locked rotor current, sound power level or shell diameter is published for this part number in the documents reviewed, the dimension field is printed as an unlabelled string, and none of those figures has been estimated anywhere in this guide.
