Disclosed is a re-cooling type air conditioning apparatus, comprising a heat supply circulation loop, wherein a liquid refrigerant getting out of a refrigerant storage tank (1) enters a condensation evaporator (9) after being pressurized by a cryogenic liquid pump (3), and the cooling amount is transferred to a backflow refrigerant with a relative high temperature, then sent to a user system (6) for heat supply after being pressurized by a compressor (5) with a rising temperature. A refrigerant gas getting out of the user system (6) enters the condensation evaporator (9) and returns to the refrigerant storage tank (1) after passing through a throttle valve (10); and a cold supply circulation loop, wherein the liquid refrigerant getting out of the refrigerant storage tank (1) enters the condensation evaporator (9) after being pressurized by the cryogenic liquid pump (3), and the cooling amount is transferred to a backflow refrigerant of a re-cooling channel, and the cooling amount as well as the refrigerant with a rising temperature are released into the user system (6) for cold supply. The refrigerant gas getting out of the user system (6) returns to the refrigerant storage tank (1) after passing through the compressor (5), the condensation evaporator (9) and the throttle valve (10). The device does not have to use the outdoor device of the traditional air conditioner. |
