Abstract
Provided is a temperature adjustment system that makes it possible to quickly commence heating without causing a temporary temperature decrease. A refrigerant circuit (3) of a vehicle air conditioning device (1) comprises a bypass flow path (15) that guides, to the upstream or downstream side of an evaporator (13) in a manner bypassing a condenser (11), refrigerant which has been discharged from a compressor (10). The control unit has a hot gas heating mode in which some of the refrigerant flows from the bypass flow path (15) and hot water that has flowed out of the condenser (11), with the compressor (10) as a heat source, is guided to a heater core (18) to heat air, and a high pressure refrigerant control mode in which, while the hot gas heating mode is carried out, the pressure of the refrigerant flowing through the condenser (11) is maintained to be a prescribed value or more.
