Working Principle of the GQR16TG Compressor
The GQR16TG hermetic compressor works by compressing low-pressure refrigerant vapor from the evaporator and sending it to the condenser at high pressure.
The process occurs in several steps:
- Suction Stage – Low-pressure refrigerant gas enters the compressor from the evaporator.
- Compression Stage – The motor-driven piston compresses the refrigerant gas, increasing its pressure and temperature.
- Discharge Stage – The high-pressure refrigerant gas flows to the condenser.
- Condensation Process – In the condenser, the refrigerant releases heat and turns into liquid.
This continuous cycle produces the cooling effect inside refrigeration equipment.
