Abstract
A vehicle-mounted temperature controller used in a vehicle having a motor, a battery, and a PCU is provided with a low temperature circuit and a refrigeration circuit. The low temperature circuit has a battery heat exchanger, a PCU heat exchanger, a radiator, and a chiller, and the cooling water circulates through them. The refrigeration circuit has a condenser and the chiller absorbing heat from the cooling water to the refrigerant, and the refrigerant circulates through them. The low temperature circuit is configured to be able to switch connection states between a first state where the battery heat exchanger and the chiller are connected, the PCU heat exchanger and the radiator are connected, and the battery heat exchanger and the chiller are not connected to the PCU heat exchanger and the radiator, and a second state where the chiller, the PCU heat exchanger, and the radiator are connected.
