Abstract

See full text

An air conditioning device for a vehicle includes: a refrigeration cycle including a compressor, a condenser, an expansion valve, and an evaporator through which a refrigerant is sequentially flowed; a high-temperature heat medium circuit through which a high-temperature heat medium has exchanged heat with the refrigerant in the condenser is circulated; a low-temperature heat medium circuit through which a low-temperature heat medium has exchanged heat with the refrigerant in the evaporator is circulated; a connection line connecting the high-temperature heat medium circuit to the low-temperature heat medium circuit; vehicle interior heat exchangers allowed to be introduced the heat medium thereinto; and a switching unit which switches an operation state of the air conditioning device to a first mode allowing to connect the vehicle interior heat exchangers to the high-temperature heat medium circuit, a second mode allowing to connect the vehicle interior heat exchangers to the low-temperature heat medium circuit, or a third mode not allowing to connect the vehicle interior heat exchangers to any one of the high-temperature heat medium circuit and the low-temperature heat medium circuit.
