The company has developed a carbon dioxide heat pump circulation loop, including compressor, water cooling heat exchanger, casing heat exchanger, throttling device, and evaporator. Each component is connected by pipes as follows: the outlet of the compressor, the water cooling heat exchanger The refrigerant pipe, the tube side of the casing heat exchanger, the throttling device, the evaporator, the casing side of the casing heat exchanger, and the inlet of the compressor are connected in sequence, and the carbon dioxide refrigerant passing through the water cooling heat exchanger is introduced into the casing heat exchanger. The tube side of the exchanger, and the low-temperature carbon dioxide gas at the outlet of the evaporator is introduced into the shell side of the casing heat exchanger to cool the carbon dioxide refrigerant in the tube side and liquefy it. The liquefied carbon dioxide refrigerant enters the throttling device and is throttled. After decompression, it enters the evaporator for evaporation, thereby realizing the circulation of the carbon dioxide heat pump circulation loop.
