Abstract
A vehicle air-conditioning device includes a compressor 2, a radiator 4, an outdoor heat exchanger 7, a first heat medium circulating device 61 to let a first heat medium circulate in a heat medium heating heater 66, and a second heat medium circulating device 62 to let a second heat medium circulate in a battery 55. The first heat medium circulating device has a first heat medium heat exchanging unit 65A which exchanges heat between a refrigerant and the first heat medium. The second heat medium circulating device has a second heat medium heat exchanging unit 65B which exchanges heat between the first heat medium and the second heat medium.
Claims20
A vehicle air-conditioning device which conditions air of a vehicle interior, comprising:
- a compressor to compress a refrigerant;
- an air flow passage through which the air to be supplied to the vehicle interior flows;
- a radiator to let the refrigerant radiate heat, thereby heating the air to be supplied from the air flow passage to the vehicle interior;
- an outdoor heat exchanger provided outside the vehicle interior to let the refrigerant absorb heat;
- and
- a control device,
- wherein the vehicle air-conditioning device includes a first heat medium circulating device to let a first heat medium circulate in a heating device for heating the first heat medium, and
- a second heat medium circulating device to let a second heat medium circulate in a heat generating device mounted on a vehicle,
- wherein the first heat medium circulating device has a first heat medium heat exchanging unit to let heat exchange between the refrigerant and the first heat medium;
- and
- wherein the second heat medium circulating device has a second heat medium heat exchanging unit to let heat exchange between the first heat medium and the second heat medium.
