Problems solved by technology

[0003] On the other hand, for example, if the battery is charged and discharged in an environment where the temperature becomes high due to self-heating caused by charging and discharging, etc., there is a risk that deterioration will increase and eventually cause malfunction and damage.
In addition, charge and discharge performance degrades even in low temperature environments

Abstract

The invention is to provide a vehicle air-conditioning device capable of continuing to condition the air inside a vehicle compartment without failure, even when an abnormality occurs which pertains to information required for temperature control of a temperature control target installed in the vehicle. The present invention is equipped with a device temperature adjustment apparatus 61 for adjusting the temperature of a battery 55 installed in a vehicle. Meanwhile, a control device (heat pump controller) has a first operation mode for controlling the temperature of the battery 55 using the device temperature adjustment apparatus, and a second operation mode which does not perform a battery 55 temperature control. When there is an abnormality in the information required for the battery 55 temperature control, execution of the first operation mode is prohibited and execution of the second operation mode is permitted.

Description

technical field [0001] The present invention relates to a heat pump type air conditioner for air-conditioning the interior of a vehicle, and more particularly to an air conditioner capable of adjusting the temperature of a temperature-regulated object installed in the vehicle. Background technique [0002] Due to environmental problems emerging in recent years, vehicles such as electric vehicles and hybrid vehicles that drive running motors using electric power supplied from batteries mounted on the vehicles have spread. Furthermore, as an air conditioner that can be applied to such a vehicle as described above, a structure including a refrigerant circuit connected by a compressor, a radiator, a heat absorber, and an outdoor heat exchanger is developed, and the heating mode is switched and executed In the heating mode, the refrigerant discharged from the compressor dissipates heat in the radiator, and the refrigerant dissipated in the radiator dissipates heat in the outdoor ...
