Wherein the three-way valve has a first outflow port and a second outflow port. When the three-way valve is controlled to enable the first flow outlet to be communicated, the refrigerant flows in the first capillary tube, the refrigeration evaporator, the gas-liquid separator and the refrigerant converging port in sequence and then returns to the compressor, after passing through the first capillary tube, the low-pressure low-temperature refrigerant flows in the refrigeration evaporator, exchanges heat with the refrigeration evaporator and air in the refrigeration chamber, and refrigerates the refrigeration chamber. Similarly, when the three-way valve is controlled to conduct the second outlet, the refrigerant flows in the second capillary tube, the refrigeration evaporator, the gas-liquid separator and the refrigerant merging port in sequence, then returns to the compressor, flows in the refrigeration evaporator after passing through the second capillary tube, exchanges heat with the refrigeration evaporator and air in the refrigeration chamber, and refrigerates the refrigeration chamber.
