Description of Products

GMCC HSM series compressors are high-performance products designed for air conditioners, heat pumps and commercial refrigeration systems, known for their energy efficiency, quiet operation and reliability.

The HSM series is GMCC's line of fixed-speed and inverter compressors, covering a wide range of displacement models for domestic air conditioning, heat pump heating and commercial refrigeration scenarios. The series is based on an aluminium wire motor design to optimize energy efficiency and cost, and some models support refrigerants such as R22 and R410A. 

GMCC, as the world's No.1 brand in the air-conditioning compressor market, the HSM series is widely used in both domestic and international markets due to its high energy efficiency, low noise and miniaturisation advantages.

Features of Products

1. Energy efficient
15-slot, 10-pole inverter technology: The HSM series adopts an innovative 15-slot, 10-pole motor design that optimises electromagnetic performance and improves the energy efficiency ratio (COP) while reducing energy consumption. For example, its inverter rotary compressor reduces noise in the high frequency band by 7 dB and overall noise by 3 dB, enhancing user experience.

Refrigerant insulation technology: The integrated inverter rotor compressor adopts refrigerant insulation structure, COP is increased by 3% and cooling/heating capacity is increased by 2%-3%.

2. Ultimate silence
Low noise optimisation: Through electromagnetic simulation, acoustic optimisation and vibration and noise reduction technology, the HSM series compressor noise can be as low as 29 decibels at low speeds (such as ultra-high-efficiency refrigerator compressors), which is suitable for scenarios that require high levels of silence.

Full-range active noise reduction: Vibration-isolating rubber feet, low vibration exhaust pipe and other designs are adopted to reduce noise transmission during operation.

3. Miniaturisation and integration
Liquid reservoir lower structure: Breakthrough traditional design, the liquid reservoir is integrated in the lower part of the shell, so that the compressor width is reduced by 20%, and the whole machine is more compact, which is easy to install and transport.

Lightweight design: While maintaining high performance, optimise the use of materials to reduce the weight of the whole machine, suitable for space-constrained home appliances.

4. High reliability and durability
High-strength materials: The use of ductile iron scroll discs, variable wall thickness scroll design, to enhance the stability of the compressor in harsh operating conditions.

Counter-gravity oil return technology: Ensuring that the lubrication system remains efficient and reliable after long-term operation (e.g. 3,500 hours endurance test).
