Real Model Analysis | GMCC Three Main Compressors (Heat Pump / Air Conditioning / Cold Chain) Specifications & Application

For HVAC&R industry selection, checking the complete model number matters more than merely referencing product series. Most generic industry articles are broad and vague, which easily leads to mismatches during procurement and R&D selection. This article adopts fully traceable mass-production models originally manufactured by GMCC. It analyzes three benchmark models for heat pumps, residential air conditioners and cold chain equipment, delivering credible references for complete machine assembly and foreign trade selection.

1. Low-Temperature EVI Heat Pump Compressor: ASQ330N1UMU (Cooling Capacity: approx.10kW)

Basic Specifications: R410A refrigerant, DC inverter rotary type, EVI vapor injection, T3 working condition. Mass-production GMCC model for exported commercial heat pumps.

Conventional heat pump compressors suffer severe heating capacity attenuation under low ambient temperature, requiring auxiliary electric heat compensation, high energy consumption and frequent defrosting. Equipped with GMCC original EVI vapor injection structure, ASQ330N1UMU adopts mid-stage vapor injection compression cycle to improve heat exchange efficiency at low temperatures and resolve unstable heating issues in frigid environments.

Key Advantages

• Sustained heating operation at -25°C with minor capacity attenuation
• Remarkably improved COP under low-temperature conditions to cut heating energy consumption
• Supports intelligent inverter defrosting, small temperature fluctuation and stable heating continuity
• Low-temperature dedicated oil circuit design for high reliability during start-stop cycles

Applications: Export ultra-low temperature air-source heat pumps, commercial constant-temperature hot water units Selection Note: An EVI vapor injection circuit is mandatory; a standard single-loop system cannot unleash its full performance. It is a 60Hz model designed for overseas markets.

2. Residential Silent Inverter Air Conditioner Compressor: KSN98D32UFZ (1.5HP)

Basic Specifications: R32 refrigerant, wide-frequency DC inverter rotary type. Mainstream GMCC model for Class 1 energy efficiency residential indoor units.

Common pain points of residential air conditioners include low-frequency resonance, large temperature deviation and obvious nighttime noise. Optimized motor topology and rotor dynamic balance are adopted for KSN98D32UFZ, featuring stable silent operation, constant temperature, energy saving and long service life.

Key Advantages

• Optimized motor structure suppresses low-frequency hum and resonance for quiet night operation
• Wide-range stepless speed regulation delivers stable temperature without hot/cold fluctuations
• Low friction loss, minor performance attenuation after frequent long-term start-stop cycles and extended unit service life
• R32 eco-friendly refrigerant, compliant with domestic and overseas energy efficiency & export standards

Applications: Residential 1.5HP inverter wall-mounted AC units, bedroom silent air conditioners, small-size Class 1 energy efficiency cabinet AC units

3. Cold Chain Inverter Refrigerator Compressor: DZ120V1V

Basic Specifications: R600a refrigerant, inverter reciprocating type. Mass-production GMCC model for high-end air-cooled refrigerators and searchable online.

Traditional fixed-speed refrigerator compressors start and stop frequently, causing large temperature fluctuation inside cabinets, food dehydration and high continuous running power consumption. DZ120V1V continuously adjusts cooling capacity via inverter control with optimized shock absorption structure, tailored for 24/7 non-stop operation.

Key Advantages

• Inverter on-demand cooling output reduces start-stop impact and delivers uniform cabinet temperature
• Low-vibration and low-noise structure for all-day continuous operation in kitchens and living rooms
• R600a natural refrigerant, low carbon and eco-friendly, meeting global export regulations
• Stable operation, suitable for large-capacity multi-door air-cooled fresh-keeping refrigerators

Applications: Multi-door air-cooled fresh-keeping refrigerators, small commercial fresh-keeping freezers Selection Note: This reciprocating refrigerator compressor cannot directly replace rotary air conditioning compressors.
