Problems solved by technology

[0003] In this case, since the refrigerant absorbs heat from the outside air in the outdoor heat exchanger during heating, frost will grow on the outdoor heat exchanger, and the heat exchange efficiency will deteriorate and the heating capacity will drop significantly. However, the outdoor heat exchanger In the past, the defrosting of the battery was generally carried out during the charging of the battery, and it took a long time to defrost

Embodiment Construction

[0037] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. figure 1 A configuration diagram showing a vehicle air-conditioning apparatus 1 to which an embodiment of the present invention is applied. The vehicle to which the embodiment of the present invention is applied is an electric vehicle (EV) that does not have an engine (internal combustion engine). (not shown) A vehicle that is driven and travels after being supplied. Furthermore, the compressor 2 described later of the vehicle air-conditioning apparatus 1 is also driven by being supplied with power from the battery 55 .

[0038] That is, the vehicle air-conditioning apparatus 1 performs the heating operation by the heat pump operation using the refrigerant circuit R in an electric vehicle incapable of heating by engine exhaust heat, and further selectively performs the dehumidification and heating operation, dehumidification and cooling operation. Each air-conditioning...

Abstract

Provided is a vehicle air conditioner capable of controlling exhaust heat recovery from heat-generating equipment, using a relatively simple configuration. A vehicle air conditioner 1 includes a controller 32 that, in a heating operation, selects at least one of an outdoor heat exchanger 7 and a refrigerant-heating medium heat exchanger 64 on the basis of a temperature Tcell of a battery 55 or a heating medium temperature Tw, which is an index value showing the temperature of the heat-generating equipment 55, and an outside air temperature Tam. After a refrigerant that has released heat in a radiator 4 is depressurized, the controller 32 causes the outdoor heat exchanger 7 and / or the refrigerant-heating medium heat exchanger 64 that have been selected to absorb heat.

Description

technical field [0001] The present invention relates to a heat pump type vehicle air conditioner. Background technique [0002] Due to the manifestation of environmental problems in recent years, vehicles such as hybrid cars and electric cars that drive a running motor with electric power supplied from a battery mounted on the vehicle have become popular. Furthermore, as an air-conditioning apparatus applicable to such vehicles, a heat-pump-type vehicle air-conditioning apparatus having a refrigerant circuit connected to a compressor driven by electric power from a battery, a heat-radiating air-conditioning apparatus has been developed. radiator, heat absorber and outdoor heat exchanger; make the refrigerant sprayed from the compressor dissipate heat in the radiator, and make the refrigerant after the radiator dissipate heat absorb heat in the outdoor heat exchanger, thereby heating the vehicle interior; The refrigerant discharged from the compressor dissipates heat in the ...
