What is a Freon compressor?

Freon compressor, also called refrigeration compressor, is the core component of refrigeration, air conditioning and cold storage units. It is used to compress gaseous Freon refrigerant, increase the pressure and temperature of refrigerant, and cooperate with condenser and evaporator to complete refrigeration cycle, so as to realize the functions of cooling, refrigeration, air conditioning heating and refrigeration.

Core special requirements include:

Material adaptation refrigerant: for R22, R410A, R32 and other different freons, select matching metal to avoid refrigerant corrosion and chemical reaction; Flammable refrigerant models such as R32 need additional explosion-proof design.

Oil-cooling lubrication compatibility: use special refrigeration oil that is miscible with corresponding Freon, and the oil circulates with refrigerant to lubricate internal parts, and ordinary lubricating oil cannot be mixed.

Strict sealing and leakage prevention: Freon is easy to leak, which will destroy the ozone layer and produce greenhouse effect. The shaft seal and valve plate sealing structure are adopted to reduce the loss of refrigerant.

Protection against liquid impact: Freon is easy to liquefy, and gas-liquid separation structure is set to prevent liquid refrigerant from rushing into the cylinder and damaging the valve plate and piston.

Temperature and pressure interlock protection: equipped with high-pressure, low-pressure and overheating protection, automatically stop when the pressure is abnormal and the temperature is too high, so as to avoid pipeline bursting and burning parts.

Silent damping structure: it is mostly used in indoor air conditioners and commercial cold storage, with damping pads and silencing structures to reduce running noise and vibration.

Generally speaking, Freon compressor is the core pressurization equipment of air conditioning and cold storage refrigeration system, which relies on compressed refrigerant to complete the refrigeration cycle; The core requirements are matching refrigerant and refrigeration oil, sealing and leakage prevention, preventing liquid hammer and multiple protection of pressure and temperature, which are widely used in household air conditioners, cold chain cold storage and commercial refrigeration equipment.
