Abstract
An air conditioning apparatus includes a refrigerant tank, a cryogenic liquid pump, a condensing evaporator, a compressor, a user system, a throttle valve, a first reversing valve, and a second reversing valve. It operates in two modes. In the first mode, the refrigerant in the refrigerant tank flows sequentially from the refrigerant tank, the cryogenic liquid pump, the condensing evaporator, the first reversing valve, the compressor, the second reversing valve, the user system, the first reversing valve, the second reversing valve, the condensing evaporator, the throttle valve, and back to the refrigerant tank. In the second mode, refrigerant in the refrigerant tank flows sequentially from the refrigerant tank, the cryogenic liquid pump, the condensing evaporator, the first reversing valve, the second reversing valve, the user system, the first reversing valve, the compressor, the second reversing valve, the condensing evaporator, the throttle valve, and back to the refrigerant tank.
