Taikang Compressor Introduction of positive displacement compressor

Taikang Compressor Introduction of positive displacement compressor The compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe and drives the piston to compress it through the operation of the motor. , Discharges high-temperature and high-pressure refrigerant gas into the exhaust pipe to provide power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).

Five items to pay attention to when using Copeland compressors

Copeland compressors are strictly forbidden to perform pressure test under oxygen, and for nitrogen without safety valve! Improper use will cause an explosion and cause casualties. Some users have already experienced this situation. I hope that all dealers promptly remind the installation personnel and use it as a warning. They must follow the operation process.
