Refrigeration System Refrigeration Compressor
The refrigeration compressor unit consists of four main components: refrigeration compressor, condenser, cooler and solenoid valve, as well as oil separator, liquid storage barrel, sight glass, diaphragm hand valve, return air filter and other components.

1. Using multiple compressors in parallel, you can choose the system cooling capacity configuration to achieve the best configuration
2. Multiple compressors are connected in parallel for centralized cooling. When one of the compressors fails, it will not affect the operation of the entire system, the temperature of the cold storage will not fluctuate, and the failed compressor can be disassembled and repaired separately.
3. When only part of the cold storage is opened, the system can centrally refrigerate the opened cold storage under automatic operation, which can greatly shorten the pre-cooling time, ensure the freshness of the fruit and extend the fresh-keeping time.
4. When only part of the cold storage is opened, the system can automatically control the start and stop of the compressor according to the load in the automatic operation state to save energy. (You can also manually turn off some compressors to stop working).
5. The system will automatically accumulate the running time of the compressor and run alternately to prevent compressor wear and extend the life of the compressor.
6. When some compressors of the unit are working, the condenser has a large amount of remaining surface area, which can improve the heat exchange effect, reduce the condensing pressure, and improve the working efficiency of the unit.
7. Microcomputer control system makes centralized control possible, can realize remote fault telephone alarm, and realize unattended.
