The present invention provides a vehicle air-conditioning apparatus capable of preventing the temperature of a temperature-controlled object from rising excessively. This vehicle air-conditioning apparatus is provided with a compressor (2), a heat absorber (9), a solenoid valve (35), a refrigerant-heat medium heat exchanger (64), and a solenoid valve (69). A control device has an air conditioning (priority) plus battery cooling mode in which an operation of the compressor (2) is controlled on the basis of the temperature of the heat absorber, and the solenoid valve (69) is controlled to be opened or closed on the basis of a heat medium temperature (Tw). In the air conditioning (priority) plus battery cooling mode, when the temperature of a battery (55) is equal to or higher than a predetermined upper limit value TcellUL1, or becomes higher than the predetermined upper limit value TcellUL1, the solenoid valve (69) is fixed in an open state.
提供一种能够将被调温对象的温度过剩上升的不良状况避免于未然的车辆用空气调节装置。具备压缩机(2)、吸热器(9)、电磁阀(35)、制冷剂-载热体热交换器(64)和电磁阀(69)。控制装置具有空气调节(优先)+电池冷却模式,所述空气调节(优先)+电池冷却模式是基于吸热器的温度对压缩机(2)的运转进行控制、基于载热体温度(Tw)对电磁阀(69)进行开闭控制的模式。在该空气调节(优先)+电池冷却模式下,在电池(55)的温度成为规定的上限值TcellUL1以上或成为比上限值TcellUL1高的情况下,将电磁阀(69)固定为打开的状态。
