Ningguo Kingcool Import and Export Co., Ltd is a China-based Compressor For Air Conditioner & Refrigerator Manufacturers and supplier serving HVAC assembly plants, appliance service networks and wholesale distributors. We combine our own metalized polypropylene film capacitor production with an agency supply chain for air conditioner and refrigerator accessories, so compressors, run capacitors, motors, thermostats and controls can be sourced together.
Our compressor range covers reciprocating, rotary and scroll architectures in fixed-speed and inverter versions, matched to the cooling capacity, refrigerant, electrical supply and mounting envelope of each project.
Our Compressor Range and Where Each Type Fits
We stock and configure compressors across the main hermetic architectures used in residential, commercial and light industrial cooling. Selection starts from the working point rather than the model number: heat load, evaporating and condensing temperature, refrigerant and supply voltage determine which family is appropriate.
| Compressor Type | Typical Application | Operating Character | Typical Capacity Band |
|---|---|---|---|
| Reciprocating | Household refrigerators, freezers, display cabinets, small condensing units | Simple structure, tolerant of high pressure ratios, low swept volume | Small to medium |
| Rotary | Split air conditioners, heat pumps, window and portable units | Compact, continuous compression, reliable starting under load | 9000–24000 BTU class |
| Scroll | Commercial HVAC, chillers, high-end residential systems, refrigeration racks | High volumetric efficiency, low vibration and noise, fewer moving parts | Medium to large, up to 30HP class |
| Inverter rotary and scroll | Variable-load air conditioning, inverter refrigerators, precision cooling | Variable speed capacity control, improved part-load efficiency | Matched to drive and system turndown |
Brand-specific options in our catalogue include LG, Samsung, Panasonic, SANYO, Copeland, Daikin, GMCC and Hitachi units, covering R134A, R410A and R22 systems. Where a project calls for a specific footprint or connector position, we confirm the drawing before the order is placed.
Critical Specifications We Confirm Before Quotation
Compressor performance is only meaningful against a defined working point. We ask for the parameters below so the proposal reflects the actual system rather than a catalogue headline figure.
- Cooling capacity — BTU/hr or kW at the specified evaporating and condensing temperatures.
- Refrigerant — R134A, R410A, R22 or other, with the associated oil type and charge limits.
- Electrical supply — 110V or 220V/208–230V, 50Hz or 60Hz, single-phase or three-phase.
- Efficiency target — EER, COP or SEER values required by the destination market's energy rules.
- Noise and vibration — relevant where the condensing unit sits close to occupied space.
- Physical envelope — base plate dimensions, mounting bolt pattern, suction and discharge connection orientation.
- Starting method — direct-on-line, PTC or run capacitor assisted, with the matching capacitor supplied from our own capacitor line.
Configuration Options and Customization
We configure compressors around the system architecture rather than selling a single default variant. Fixed-speed units suit stable load profiles and keep the bill of materials simple; inverter-driven units give capacity modulation for comfort control and part-load energy savings.
Fixed-Speed Units
On/off control with simple wiring, lower initial cost and straightforward service replacement in existing equipment.
Inverter Units
Variable frequency operation for capacity matching, softer starting current and improved seasonal efficiency.
Accessory Matching
Run and start capacitors, overload protectors, contactors and terminal covers supplied as a matched set.
Because we also produce metalized polypropylene film capacitors, the run capacitor supplied with a compressor order is drawn from our own production rather than a third-party substitution. Related electrical items such as relays, overload protectors and delay timers can be consolidated into the same shipment.
Quality Control and Acceptance Testing
Every compressor is checked before packing. Our inspection routine covers the points that most often cause field failures in air conditioning and refrigeration assemblies.
- Electrical test for winding resistance, insulation and current draw at rated voltage.
- Pressure and leak check to confirm refrigerant containment and joint integrity.
- Run-in performance validation under simulated operating conditions.
- Visual inspection of terminals, mounting feet, paint finish and nameplate data.
- Documentation of test results against the agreed specification for the shipment.
Acceptance criteria are agreed at order stage, so the incoming inspection at your plant can be checked against the same parameters we record before dispatch.
Installation, Line Integration and Maintenance
Compressor installation quality decides whether the rated capacity is actually delivered. We supply technical documentation and installation guidance with each unit, covering brazing practice, evacuation, oil charge and electrical connection.
- Mounting through the correct grommets and bolts to control vibration transmission into the chassis.
- Suction and discharge line sizing consistent with the compressor's connection diameters.
- Correct capacitor rating and overload setting for the winding characteristics of the unit.
- System evacuation and moisture control before charging, to protect the winding insulation.
- Routine maintenance: coil cleaning, refrigerant level checks and terminal inspection.
Spare parts and replacement units are supplied through the same channel as the original order, and we keep compatible accessories such as motor run capacitors available for service stock.
One-Stop Sourcing Across the HVAC Parts Range
Compressors rarely ship alone. Our catalogue covers the surrounding components so a single purchase order can cover a complete repair kit or production batch. The Air-Conditioner Parts range includes control systems, temperature controllers, contactors, transformers, motors, defrost timers, thermostats, fan blades and brackets, while the refrigeration side covers capillary tubes, filter driers, copper tube, valves and fittings.
This consolidation reduces the number of suppliers, shipping documents and inspection routines a project has to manage, and it lets us check electrical compatibility between the compressor, capacitor and control components before the goods leave our warehouse.
Information We Use to Configure Your Solution
To prepare an accurate configuration and quotation, we work from the following project inputs. Where a value is not yet fixed, we can propose a starting point and confirm it against the system design.
| Input | Why We Need It |
|---|---|
| Application type | Air conditioner, refrigerator, heat pump, chiller or condensing unit determines the compressor family. |
| Cooling capacity and working point | Sets the displacement and the performance curve to be quoted. |
| Refrigerant and system design | Confirms oil compatibility, pressure rating and connection type. |
| Voltage, phase and frequency | Matches the unit to the destination market supply and starting method. |
| Preferred brand or type | Keeps the replacement compatible with existing equipment or production line approvals. |
| Operating environment | Ambient temperature, humidity and altitude affect capacity correction and enclosure choice. |
| Quantity, packing and delivery scope | Determines carton configuration, palletisation and shipping documentation. |
Frequently Asked Questions
Can you supply compressors for both air conditioners and refrigerators?
Yes. Our range covers reciprocating compressors for refrigerators, freezers and display cabinets, and rotary or scroll compressors for air conditioners, heat pumps and commercial cooling. The correct family is selected from the working point and refrigerant rather than from the appliance category alone.
Do you offer inverter compressors?
We supply inverter-driven rotary and scroll compressors, including Hitachi and Panasonic options, for systems that need variable capacity control. Inverter selection also depends on the drive and control board in the system, so we confirm the electrical interface before quoting.
How is compressor quality verified before shipment?
Each unit passes electrical testing, pressure and leak checking, performance validation under simulated operating conditions and a visual inspection of terminals, mounting and nameplate. Test records are kept against the agreed specification for the shipment.
Can compressors be combined with other parts in one order?
Yes. Compressors can be consolidated with capacitors from our own production, overload protectors, contactors, thermostats, motors and refrigeration fittings. Consolidating the order keeps electrical compatibility checked in one place and reduces shipping and documentation overhead.
What information is needed to receive a quotation?
Send the application type, required cooling capacity and working point, refrigerant, supply voltage and frequency, preferred brand or compressor type, operating environment and order quantity. With those inputs we can propose a configuration, confirm the accessory set and prepare the quotation.
Are samples available for evaluation?
We can arrange sample compressors for testing before a volume order. Sample cost and freight are normally covered by the customer, and we confirm the exact arrangement together with the model and quantity in the quotation.
