Compressor failure and elimination

The compressor is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant liquid to the exhaust pipe to provide power for the refrigeration cycle.

Analysis on the noise of air-cooled chillers

When many users use air-cooled chillers, they usually have no noise problems because they have gone through a comprehensive test at the beginning. However, with long-term use and the user’s failure to maintain it carefully,

Maintenance method for wear of refrigerator refrigeration compressor

　The application of screw refrigeration compressors is becoming more and more common, and some of them have entered the period of frequent failures. When the abrasion of the female and male rotors, body, and exhaust end seat of the refrigeration compressor reaches above 0.65rnm, vibration will occur when the refrigeration compressor is running, the sound is abnormal, the cooling capacity is reduced, and the compressor cannot work normally.

What is Variable Valve Timing?

VVT refers to variable valve timing. It adjusts the amount of intake (or exhaust), as well as the timing and angle of solenoid valves opening and closing according to the operating conditions of the engine.
