Abstract

The application discloses a refrigeration system and a control method, device, equipment and medium thereof, to provide a refrigeration system coexisting air-cooled refrigeration mode and liquid-cooled refrigeration mode. The system comprises a compressor circulation heat exchange system and a natural cold source circulation heat exchange system for heat exchange through an intermediate heat exchanger. The compressor circulation heat exchange system comprises a throttling valve, a first condenser and at least one compressor connected in sequence on the primary side of the intermediate heat exchanger, one end of the primary side of the intermediate heat exchanger is connected with the throttling valve, and the other end is connected with the common end of the at least one compressor. The natural cold source circulation heat exchange system comprises a pump, an air-cooled heat exchanger, a liquid-cooled heat exchanger and a second condenser connected on the secondary side of the intermediate heat exchanger. The air-cooled heat exchanger and the liquid-cooled heat exchanger are connected in parallel and then connected between the pump and the second condenser. One end of the secondary side of the intermediate heat exchanger is connected with the second condenser, and the other end is connected with the pump.
