VEHICLE TEMPERATURE CONTROL DEVICE AND METHOD FOR CONTROLLING VEHICLE TEMPERATURE CONTROL DEVICE

A vehicle temperature control device according to one embodiment of the present invention is provided with: a first circuit through which a first heat medium flows; a reservoir for gas-liquid separation of the first heat medium; a compressor that compresses the first heat medium; an air-conditioning heat exchanger that exchanges heat between the first heat medium and air; a first expansion valve; a second expansion valve; and a heat exchange amount adjustment unit that adjusts the amount of heat exchange in the air-conditioning heat exchanger. The first circuit has a first loop and a first sub-loop, and a first heat medium circulates in the first loop and the first sub-loop at the same time. In the first loop, a first heat medium circulates through an accumulator, a compressor, an air-conditioning heat exchanger, and a first expansion valve in this order. In the first sub-loop, a first heat medium circulates through an accumulator, a compressor, and a second expansion valve in this order. 本发明提供车辆用调温装置以及车辆用调温装
