Bitzer semi-closed compressor uses high-strength material to make the casing, and the internal flow channel is designed reasonably to ensure smooth gas flow and reduce energy loss. The main body of the compressor includes cylinders, pistons, connecting rods, crankshafts and other components, and the gas is compressed by the reciprocating motion of the piston. Its structure also includes an intake system, an exhaust system, a cooling system and a control system to ensure the efficient and stable operation of the compressor.

1. Working principle
The compressor inhales low-temperature and low-pressure refrigerant gas from the intake pipe, compresses it by driving the piston through the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation → expansion → evaporation.

2. Features
High efficiency The advanced structural design is adopted to achieve a high-efficiency compression process, and the energy consumption is reduced by 15%-20%.
Maintenance convenience The compact structure is easy to maintain and repair, and the maintenance cost is reduced.
Noise level The high-quality wear-resistant parts and the best mass balance design are adopted, and the operating noise is low.
Wide operating adaptability Adapts to high/medium/low temperature applications, supports a variety of refrigerants (such as R22, R404a, etc.), and meets environmental protection requirements.
Reliability Equipped with electronic protection module and built-in differential pressure safety valve, real-time monitoring of motor temperature to ensure safe operation.
Wide cooling capacity range Cooling capacity range 4~44kW, can operate normally below -60℃, meeting the needs of extreme working conditions.
