Key facts at a glance

What is the GREE Landa QXD-C184A030A?

GREE Landa QXD-C184A030A is a hermetic single rotary compressor built by Zhuhai Landa Compressor Co., Ltd., the compressor business of Gree Electric Appliances, for air conditioning, drier, refrigeration and chiller duty. It is catalogued against an 18.4 mL/rev displacement, 2,750 W of cooling capacity, 820 W of input power and a COP of 3.35 W/W on a 220-240 V 50 Hz single-phase supply, and the manufacturer files it as part of the Gree Landa fixed speed rotary compressor range.

On this site the model sits inside two catalogues: this site's own Gree Landa rotary compressor range, and the wider line of rotary compressors for air conditioning and refrigeration that the range belongs to.

Its own catalogue entry, carrying the full specification table used throughout this guide, is the QXD-C184A030A product page.

GREE publishes the Landa fixed speed rotary compressor line on its global corporate site, and names Landa Compressor among its core industrial brands on the GREE Industrial Product page. The manufacturer's own corporate site is Zhuhai Landa.

Two features of this particular model deserve attention before the numbers. First, its usage line is published as a T3 working condition rather than as a plain application list, and T3 is a hot-climate test condition rather than a marketing preference. Second, the same page carries a contradiction in its refrigerant labelling that a buyer has to settle before ordering, because the substance decides which regulations the finished product answers to.

Technical specifications

Model	QXD-C184A030A	Product data sheet, model row
Displacement	18.4 mL/rev	Data sheet, displacement row
Cooling capacity	2,750 W (9,386 Btu/h)	Data sheet, capacity row. The page prints the imperial figure as 9386TU/H
Input power	820 W	Data sheet, input row, and the page's own specification bullet
COP	3.35 W/W	Data sheet, COP row
Refrigerant	R290	Data sheet, refrigerant row. The same page's bullet block prints R22
Power supply	220-240 V, 50 Hz, single phase	Data sheet, voltage row, and the bullet block
Compressor height	273 mm	Data sheet, height row
Rated usage	T3 working condition	Data sheet, usage row
Application statement	Air conditioning, drier, refrigeration, chiller	Bullet block, application bullet

The numeric block is internally consistent, which matters when a page also contains a labelling error. Dividing the published capacity by the published input gives 2,750 divided by 820, which is 3.35 and matches the printed COP exactly. Converting 2,750 W to imperial units gives 9,383 Btu/h at 3.412 Btu/h per watt, which matches the printed 9,386 Btu/h to within rounding. The four figures therefore belong to one test point rather than being assembled from different sources, and a buyer can treat the block as a self-consistent starting point for sizing.

What the page does not print is the rating condition behind those figures. The usage row says T3, but a capacity figure is only comparable with another capacity figure when both carry the same stated test condition. Treat 2,750 W as a catalogue value at a T3 condition and confirm the exact test point on the manufacturer datasheet before using it in a performance calculation.

Performance characteristics

The performance claims for this model come from two published places: the Gree Landa range description that GREE and its distributors publish with the product record, and the listing summary this site publishes for this model. Each is presented here as a published claim rather than as an independently measured result.

• Wide application envelope. The range copy states that a wide application envelope suits varied applications. For a T3-rated unit the useful part of that claim is high ambient tolerance, which is what the T3 designation on the usage line is doing.
• IDV technology for part-load efficiency. The range copy credits an IDV technology with improving part-load efficiency at minimal redesign cost. The published material reviewed for this guide does not expand the acronym, so confirm what the term covers for this specific model rather than reading a drive type into it.
• Robustness and system reliability. The range copy describes a step change in compressor robustness and system reliability. No test data behind that statement is published on the product page.
• Manifold configurations for staged modulation. The range copy mentions manifold configurations with high reliability for staged modulation. That is multi-compressor language, and this model is a single rotary compressor, so treat this line as range-level copy rather than as a description of QXD-C184A030A.
• Low sound and high ambient adaptability. The range description states that Gree Landa compressors are designed with low sound and high adaptability to ambient temperature. No sound power or sound pressure figure is published for this model, so the claim cannot be turned into a dB target without a datasheet.
• Compact body and built-in motor protection. The listing summary this site publishes for the model describes it as compact, low noise and fitted with built-in motor protection. The protection statement is not repeated in the product data sheet, so it is recorded here as site copy and should be confirmed on the manufacturer datasheet.

Two further notes on the published copy are worth recording because they affect how much weight to give it. The range description states that the brand provides highly reliable scroll compressors, while the product itself is a rotary compressor, so that sentence is shared boilerplate and is inaccurate for this family. The range copy also claims that the compressor provides a variety of environmentally friendly refrigerants, which is true of the Gree Landa range as a whole rather than of any single model.

The refrigerant question: R290 or R22?

The QXD-C184A030A page labels its refrigerant twice and the two labels disagree. The specification bullet block prints Refrigerant Gas: R22. The Product Details table prints Refrigerant: R290. Only one of those can be right, and the evidence points to the table.

The page's own data sheet says R290. The identical data sheet, including the identical capacity, input, COP, voltage and height values, publishes R290 on a second domain carrying the same Gree Landa product record. The sibling model on the same site, QXD-C184, prints R290 in both of its labelling positions, with the same 18.4 mL/rev displacement, the same 820 W input and the same 3.35 COP. The manufacturer's own 2022 product manual states that the QXD-C184 compressors were developed for R290 air conditioners, and that manual is available as a PDF from Zhuhai Landa.

The model prefix carries the substance. In the Gree Landa rotary naming scheme the letters immediately after QX distinguish the refrigerant family, and the D in QXD marks the R290 family. The same compressor range lists its QXD models under R290 and its QX models, without the D, under R22. That is consistent with the R22 bullet having been carried across from a QX series listing rather than describing this model.

Substance	Chemical name and formula	GWP100	Ozone depleting potential	Safety group
R290	Propane, CH3CH2CH3	0.02	Zero	A3
R22	Chlorodifluoromethane, CHClF2	Not stated on the sources used here	0.055	Not stated on the sources used here

Sources for the table: the R290 global warming potential of 0.02 and its A3 safety group come from the European Commission's assessment of climate-friendly alternatives to F-gases, which takes its GWP values from Annex I and II of Regulation (EU) 2024/573. The chemical names and formulae for both substances come from the designations published alongside ANSI/ASHRAE Standard 34. The R22 ozone depleting potential of 0.055 is the value in Annex C of the Montreal Protocol, published by the UNEP Ozone Secretariat. No global warming potential for R22 is quoted here because the sources used for this guide do not state one; the UNEP OzonAction description of the Montreal Protocol records that the most commonly used HCFC is nearly 2,000 times more potent than carbon dioxide, without naming a single figure for R22.

The two substances are not interchangeable options on the same platform. R22 is a hydrochlorofluorocarbon, an ozone depleting substance controlled under the Montreal Protocol, and its production and consumption have been phased out in developed countries and are being phased out in developing countries. R290 is propane. It is not fluorinated, so no global warming potential threshold written against fluorinated greenhouse gases can be applied to it as a substance, and it has an ozone depleting potential of zero.

That difference changes the design obligation, not just the labelling. R290 sits in safety group A3, the higher flammability classification, so charge limits, ventilation, leak detection and the siting of electrical components all become part of the appliance design. For heat pumps, air conditioners and dehumidifiers the product safety standard covering that class of refrigerant is IEC 60335-2-40:2022, whose scope covers ISO 817 groups A1, A2L, A2 and A3. This guide states which standard governs; it does not state that any appliance passes it.

What the T3 rating actually means

T3 is not a slogan. It is one of three standard rating conditions defined in the international test standard for non-ducted air conditioners and heat pumps. Read the definition from the standard rather than from a summary, because the ambient figure matters commercially.

Parameter	T1	T2	T3
Indoor air, dry-bulb	27 degC	21 degC	29 degC
Indoor air, wet-bulb	19 degC	15 degC	19 degC
Outdoor air, dry-bulb	35 degC	27 degC	46 degC
Outdoor air, wet-bulb	24 degC	19 degC	24 degC

Source: ISO 5151:2017, Table 1, cooling capacity rating conditions, in the edition published 2017 and confirmed in 2022 with one amendment. The standard names T1 as the rating condition for moderate climates, T2 for cool climates and T3 for hot climates, and requires equipment rated only for a hot climate to have its rating determined by tests run at T3 conditions and to be designated type T3 equipment.

So a usage line reading T3 working condition describes a compressor rated with 46 degC air entering the outdoor side, not a temperate 35 degC unit redeployed to a hotter market. For equipment destined for the Gulf, North Africa, South Asia or similar duty this is the rating condition that governs the selection, and it is the single most useful piece of information on the data sheet.

Anyone quoting a T3 ambient should quote the standard's own Table 1 value. Figures above it that circulate in supplier copy are not the T3 rating condition and should be traced to a stated test method before they are used in a selection decision.

Which applications suit the QXD-C184A030A?

The application line on the product data sheet reads air conditioning, drier, refrigeration and chiller. The listing summary this site publishes for the model adds room air conditioners, heat pumps, dehumidifiers and small condensing units. The T3 usage line narrows that list usefully.

• Air conditioning in hot climates. 2,750 W of cooling at 18.4 mL/rev places this unit in single split and light commercial duty rather than in a small portable appliance, and the T3 rating is what makes it suitable for markets where the outdoor design condition is at or near 46 degC.
• Drier duty. The data sheet application line lists driers, which is a long-run, high-ambient-cycle application where a hot-climate rating and a stable COP matter more than peak capacity.
• Refrigeration and chillers. The data sheet lists both. R290 is one of the substances the European Commission lists among the climate-friendly alternatives for stationary chillers, where fluorinated refrigerants with a GWP of 150 or more are prohibited from 1 January 2027 for units up to 12 kW, and those above a GWP of 750 for larger units.
• Heat pumps and dehumidifiers. These two applications appear in the site's listing summary rather than in the data sheet application line, and the substance supports them: R290 is listed among the climate-friendly alternatives for domestic heat pumps, and IEC 60335-2-40 is the product safety standard for electric heat pumps, air conditioners and dehumidifiers. Treat the pairing as site-stated until the manufacturer datasheet confirms it for this exact model string.
• Replacement of R22 equipment. Where an existing platform runs on R22 and cannot continue on it, a compressor already built for a non-fluorinated refrigerant removes the substance from the regulatory question. This is not a drop-in substitution; the oil, expansion device, pipe sizing, charge and safety classification of the appliance all change, and the assembly has to be re-tested.
• Equipment facing a cooling demand build-out. Global demand for cooling services is the reason refrigerant and efficiency choices now carry weight. The IEA report on the future of cooling frames the scale of that demand growth and the efficiency gap that sits inside it.

For buyers who want the same refrigerant position at a larger displacement, the site also carries a published guide to an R290 rotary compressor of a different brand, the GMCC DSG320S1UFT article, which is useful as a cross-brand comparison of how R290 rotary units are specified.

Selection advantages, stated plainly

Four points carry this model's selection case, and each one traces back to something published rather than to a claim about the range as a whole.

• It is the only model in its comparison group with a published T3 usage line. Of the four Gree Landa rotary models compared in the next section, only QXD-C184A030A has a usage row reading T3 working condition. QXD-C184, QX-C184TE030 and QX-C202TE030 publish their usage as the plain application string, with no rating condition attached. For a project whose outdoor design ambient sits at or near 46 degC, a compressor whose published rating condition already matches the duty removes an assumption from the selection.
• The refrigerant position is the one that survives the regulation. R290 is not a fluorinated substance, so the global warming potential thresholds written against fluorinated greenhouse gases in Regulation (EU) 2024/573 and in comparable national rules do not apply to it as a substance, and its ozone depleting potential is zero. Where an appliance has to clear a chiller or air conditioning prohibition date, starting from a non-fluorinated refrigerant removes an entire class of compliance work from the design file. The European Commission's list of climate-friendly alternatives is the reference used for that statement.
• The displacement, capacity, input and COP block is compact and self-checkable. 2,750 W of cooling from 820 W of input, at a published COP of 3.35 W/W, inside a 273 mm body. A buyer can verify that the figures describe one test point rather than a composite: 2,750 divided by 820 is 3.35, and 2,750 W at 3.412 Btu/h per watt is 9,383 Btu/h against the 9,386 Btu/h printed. Neither check is published on the product page, which is why it is worth doing.
• The rating condition and the frame size point at one market. A published T3 rating combined with 2,750 W of cooling at 18.4 mL/rev places this unit in single split and light commercial duty, in markets whose outdoor design ambient sits at or near 46 degC, rather than in a small portable appliance for a temperate climate. That combination is the whole of the selection argument for a project in the Gulf, North Africa or South Asia.

What the advantages do not include

Three limits belong next to the list above, because each one has been read out of supplier copy for this class of compressor at some point.

No published sound figure. The range description states that Gree Landa compressors are designed with low sound, and the site's listing summary for this model says low noise. Neither is a number. Without a sound power level in dB(A) or a sound pressure level at a stated distance, the model cannot be compared on noise against a competing unit, and the claim should not be turned into a specification target.

No certification and no third-party test report. This guide names the standards that govern this class of product. Naming a standard is not a statement that this model holds a certificate under it. The rated values on the product page are catalogue data. Any acceptance test should be run against a manufacturer datasheet and, where the project requires it, a declaration or test certificate issued for the exact model string.

Not a drop-in replacement for an R22 compressor. The dimensional envelope may match a unit being replaced, but the refrigerant, the lubricant, the expansion device, the pipe sizing, the charge and the safety classification of the finished appliance all change together. A substitution of this kind is a redesign of the refrigeration circuit and of the appliance's safety case, and the assembly has to be re-tested.

How does the QXD-C184A030A compare with the other Gree Landa rotary models?

The useful comparison is against the nearest neighbours in the same range, because they share a displacement family and a voltage class and therefore compete for the same socket. The table below reads the published values from each model's own product page on this site, as retrieved on 2026-09-22.

Model	Refrigerant as published	Displacement	Cooling capacity	Input power	COP	Height	Usage line as published
QXD-C184A030A	R290 in the data sheet, R22 in the bullet block on the same page	18.4 mL/rev	2,750 W, 9,386 Btu/h	820 W	3.35 W/W	273 mm	T3 working condition, plus air conditioning, drier, refrigeration, chiller
QXD-C184	R290 in both labelling positions	18.4 mL/rev	2,750 W, 9,386 Btu/h	820 W	3.35 W/W	267 mm	Application list only, no rating condition
QX-C184TE030	R22 in both labelling positions	18.4 mL/rev	20,916 Btu/h, printed in the bullet block only	1,975 W, printed in the bullet block only	3.1 W/W	Not usable, the page prints 29.3 mm	Application list only, no rating condition
QX-C202TE030	R22 in both labelling positions	20.2 mL/rev	3,784 W, 12,912 Btu/h	870 W	4.35 W/W	293 mm	Application list only, no rating condition

How to read the table

The refrigerant column divides the group. QX-C184TE030 and QX-C202TE030 are R22 models. Their COP figures, 3.1 W/W and 4.35 W/W, are not a like-for-like efficiency comparison against the 3.35 W/W of the R290 units, because COP depends on the refrigerant, the evaporating and condensing temperatures and the test condition, none of which is printed for the R22 pair. A higher printed COP in that column is not evidence of a more efficient compressor.

The displacement code correlates with the number, and that is a reading rather than a documented rule. The three models carrying a 184 code all publish 18.4 mL/rev, and the model carrying a 202 code publishes 20.2 mL/rev. That pattern is consistent across this group, but no naming document was found that states it, so treat it as an observed convention for the purpose of reading a model number rather than as a manufacturer definition.

Two page defects sit inside the QXD-C184A030A row, and one inside the QX-C184TE030 row. On the QXD-C184A030A product page the refrigerant is labelled twice and the labels disagree. On the QX-C184TE030 page the compressor height is printed as 29.3 mm, which is not a physical dimension for this class of compressor and is inconsistent with the 273 mm and 293 mm heights printed for the units either side of it. The same QX-C184TE030 page omits the input power and capacity rows from its data sheet table while carrying both figures in the bullet block above.

What the table does not tell you. There are no published figures in this group for sound power, oil type and charge, motor protection type, suction and discharge connection sizes, mounting footprint or starting current. Those are the fields that decide whether a compressor drops into an existing chassis, and none of them can be read off any of the four pages.

What the model code QXD-C184A030A tells you

Compressor model strings encode a family, a refrigerant position and a displacement, and reading them correctly saves a round of email. The table below separates what the published material supports from what it does not.

Segment	Reading	Basis
QX	Gree Landa rotary series prefix, shared by the rotary models in this range	The range's own model list groups QX, QXD, QXG, QXGL, QXGTL and QXGSL strings under Gree Landa rotary compressors
D	Marker separating the R290 members from the R22 members of the QX family	The range publishes its QXD models against R290 and its QX models against R22
C184	Displacement code for the 18.4 mL/rev frame	The models carrying a 184 code in this group all publish 18.4 mL/rev
A030A	Not documented in the material reviewed for this guide	No published source found that defines these characters

The two letters that matter at the quotation stage are the D and the 184. A buying enquiry that names QXD-C184A030A is asking for the R290 version of the 18.4 mL/rev frame, and a supplier who quotes a QX-C184 series unit against that enquiry is quoting the R22 equivalent of the same displacement. The suffix A030A distinguishes variants within the R290 frame, and this guide does not decode it. Ask the manufacturer or the distributor what separates the A030A variant from other suffixes in the same frame before treating two quote lines as interchangeable.

Selection checklist for the QXD-C184A030A

Eight steps, in the order they should be closed, for a project evaluating this compressor.

1. Settle the refrigerant in writing before the order, not after. The product page labels this model R290 in its data sheet and R22 in its bullet block. Request a written confirmation of the refrigerant from the supplier, quoting the model string in full, and keep that reply in the project file. Everything downstream, from the oil to the appliance safety case, follows from this one answer.
2. Confirm the test condition behind the 2,750 W rating. The usage line reads T3, and ISO 5151:2017 Table 1 gives the T3 cooling rating condition as 29 degC indoor dry-bulb, 19 degC indoor wet-bulb, 46 degC outdoor dry-bulb and 24 degC outdoor wet-bulb. Ask for the evaporating temperature, condensing temperature and subcooling or superheat that go with the published capacity, because a capacity figure without them is not reusable in a system simulation.
3. Check the 273 mm height against the actual chassis. The sibling QXD-C184 is published at 267 mm, so an installation designed around a 267 mm compressor has 6 mm less clearance than it was drawn with. Verify the height against the drawing rather than against the catalogue.
4. Obtain the fields the product page does not publish. Suction and discharge connection sizes, mounting foot pattern, oil type and oil charge, motor protection type and reset behaviour, allowable operating envelope and starting current. None of these appears on any of the four product pages compared above, and each one can invalidate a selection on its own.
5. Size the electrical supply from the input figure, not from the capacity. 820 W of input on a 220-240 V 50 Hz single-phase supply is the published figure. Locked rotor current and the starting characteristic are not published, so the circuit protection and contactor selection have to come from the datasheet.
6. Design the appliance for an A3 refrigerant. R290 sits in safety group A3 in the ASHRAE 34 designations, the higher flammability classification, and IEC 60335-2-40:2022 is the product safety standard whose scope covers ISO 817 groups A1, A2L, A2 and A3 for heat pumps, air conditioners and dehumidifiers. Charge limits, ventilation, leak detection and the siting of ignition sources belong in the design review, not in the final inspection.
7. Ask which standard edition the destination market applies. IEC 60335-2-40:2022 is the seventh edition and cancels and replaces the sixth edition of 2018, with corrigendum 1 of October 2024 included. A market working to an earlier national adoption will not accept a design file written only against the 2022 text.
8. Request the datasheet revision for this exact model string. A capacity table for the family is not the same document as a datasheet for QXD-C184A030A. Ask for the revision that names this string, along with any declaration or certificate the project needs, and record the revision number and date in the project file.

Frequently asked questions

Is the GREE Landa QXD-C184A030A an R290 or an R22 compressor?

R290. The product page labels the refrigerant twice and the two labels disagree, with the bullet block printing R22 and the Product Details table printing R290. The evidence points to the table: the identical datasheet publishes R290 on a second domain carrying the same Gree Landa record, the sibling model QXD-C184 prints R290 in both of its labelling positions with the same 18.4 mL/rev displacement and the same 3.35 COP, and the manufacturer's 2022 manual states that the QXD-C184 compressors were developed for R290 air conditioners. Confirm the refrigerant in writing before ordering regardless of which label is correct on the day you read the page.

What does the T3 working condition on the data sheet mean?

It means the capacity was rated with 46 degC air entering the outdoor side. T3 is one of three cooling rating conditions in the international test standard for non-ducted air conditioners and heat pumps, and the ISO 5151:2017 standard record identifies T1 as the rating condition for moderate climates, T2 for cool climates and T3 for hot climates, with equipment rated only for a hot climate required to be tested at T3 and designated type T3 equipment. The temperate comparison figure is 35 degC, which is the T1 condition, so a T3 unit is not a T1 unit redeployed to a hotter market.

What capacity does the QXD-C184A030A deliver, and at what condition?

2,750 W of cooling capacity, equivalent to the 9,386 Btu/h printed on the page, from 820 W of input at a published COP of 3.35 W/W on a 220-240 V 50 Hz single-phase supply. The rating condition is the T3 hot-climate condition described above. The page does not publish the evaporating and condensing temperatures behind the figure, so treat 2,750 W as a catalogue value at a T3 condition and obtain the full test point before using it in a performance calculation.

Can the QXD-C184A030A replace an R22 compressor directly?

No. The refrigerant, the lubricant, the expansion device, the pipe sizing, the charge and the safety classification of the finished appliance all change at the same time, and R290 sits in safety group A3 while R22 does not. A compressor swap of this kind is a redesign of the refrigeration circuit and of the appliance safety case, and the finished product has to be reassessed against IEC 60335-2-40:2022 and re-tested. Where the goal is to remove an ozone depleting substance from an existing platform, budget for a product redesign rather than for a component substitution.

Is R290 safe to use in this type of equipment?

R290 is propane and sits in safety group A3, the higher flammability classification. It is used widely in sealed refrigeration and air conditioning equipment under design rules written for that class, so the question is a design question rather than a substance question. Charge limits, ventilation, leak detection and ignition source control have to comply with the standard edition in force in the destination market, and for heat pumps, air conditioners and dehumidifiers that is IEC 60335-2-40:2022, whose scope covers ISO 817 groups A1, A2L, A2 and A3.

Which Gree Landa rotary models on this site run on R290?

The QXD entries do, and the QX entries in the same displacement family do not. Two QXD models are published in the range, QXD-C184A030A and QXD-C184, both listing 18.4 mL/rev, 2,750 W, 820 W input and a 3.35 W/W COP. The wider Gree Landa rotary compressor range is presented as a paginated catalogue dominated by QX, QXG, QXGL and MGu series model strings, which are the R22, R410A and inverter families. Model articles for other compressors are collected in the site's news and model guide index.

Explicitly not verified in this guide

• No global warming potential for R22 is quoted. The regulatory and treaty sources used here do not state one, so the comparison table leaves that cell as not stated rather than filling it from a secondary summary.
• No count of the catalogue entries in the Gree Landa range is quoted. The group page presents the range as a paginated catalogue and does not print a total on the rendering retrieved for this guide, so no figure is asserted here.
• The meaning of the C and A030A characters in the model string is not documented in the material reviewed, and no decoding of them is offered beyond the observed conventions recorded above.
• The IDV acronym is not expanded in any published material reviewed for this guide, and no decoding of it is offered. The range copy credits it with improving part-load efficiency; what it covers for this specific model is unconfirmed.
• No standard named here is a certification held by this model. Naming ISO 5151, ASHRAE 34, IEC 60335-2-40 or Regulation (EU) 2024/573 is not a statement that QXD-C184A030A holds a certificate, a declaration or an approval under any of them. None is claimed.
• The rated values are catalogue data, not third-party test results, and the rating point behind the published capacity is not printed on the page.
• The product page carries three recorded defects: a refrigerant bullet that prints R22 against an R290 datasheet, a range description that calls these rotary compressors scroll compressors, and a usage row that names a rating condition without publishing the test point behind the capacity figure.
• The GREE global site page linked in this guide describes a different model. Its figures, 84 mL/rev, 21,600 W, a minus 25 degC to 70 degC range and up to 10 HP, belong to QXAS-H84sN345 and must not be read as properties of QXD-C184A030A.
