Cold station unit, integrated cold station system and control method thereof and related devices

Abstract

The application discloses a cold station unit, an integrated cold station system and a control method thereof and related equipment, wherein the cold station unit comprises a circulating refrigerant pipeline, a compressor, a condenser and a liquid pump connected to the circulating refrigerant pipeline, the circulating refrigerant pipeline is used for circulating refrigerant medium, the compressor is connected in parallel with a first bypass pipeline, the liquid pump is connected in parallel with a second bypass pipeline, the compressor and the first bypass pipeline are selectively connected or disconnected, the liquid pump and the second bypass pipeline are selectively connected or disconnected, and a throttling device and an evaporator of the terminal unit are connected in series in the circulating refrigerant pipeline. According to the application, the compressor and / or the liquid pump can be selected to perform refrigeration according to the outdoor temperature, the liquid pump heat pipe technology is applied, the compressor does not need to be operated, and only the liquid pump is used to drive the heat pipe to perform refrigeration under the condition that the outdoor temperature is relatively low, or the liquid pump is used to assist refrigeration when the compressor performs refrigeration, so that the compressor load is reduced, and the energy consumption is reduced.
