AIR CONDITIONER FOR VEHICLE

WIPO Patent Application WO/2017/163659

A1

Provided is an air conditioner for a vehicle with which it is possible to effectively use the heat of a coolant when heating a plurality of objects to be heated. This air conditioner for a vehicle is equipped with: a compressor that compresses a refrigerant; a condenser that performs heat exchange between a high-temperature, high-pressure refrigerant and a coolant that is emitted from an engine cooling unit; a first object to be heated that performs heat exchange between the coolant heated by heat exchange and air fed into a vehicle interior; and an evaporator that performs heat exchange between the coolant introduced into the engine cooling unit and a low-temperature, low-pressure refrigerant. The air conditioner is further provided with: a coolant channel for distributing the heated coolant to the first object to be heated; a coolant channel for distributing the heated coolant to a second object to be heated that is separate from the first object to be heated; an opening/closing unit that opens/closes the coolant channels; and a control unit that controls the opening/closing unit such that an inflow destination to which the heated coolant is distributed is switched from the second object to be heated to the first object to be heated at a prescribed timing.
