<p>An onboard device temperature adjusting apparatus includes a vehicle air-conditioning apparatus (100) using a cooling cycle including a compressor (11), a condenser (12), and an evaporator (10). A high-pressure side reservoir mechanism (15, 51) comprising a sub-cool modulator (15) or a receiver (51) is disposed downstream of the flow of refrigerant in the condenser (12). Further downstream of the reservoir mechanism (15, 51), a first choke (16) for squeezing the flow of refrigerant, a heat exchange unit (20) for exchanging heat with an onboard device (5) in which the refrigerant flows, a second choke (17) for squeezing the flow of refrigerant, and the evaporator (10) are arranged in sequence. The opening angle of the first choke (16) is controlled by a control device (7, 25) on the basis of the temperature of a battery as the onboard device (5) such that the onboard device (5) can be heated or cooled via a heat exchange fluid in the heat exchange unit (20). Thus, heating and warming of an automobile component such as the battery can be both achieved by using a highly efficient refrigeration cycle, whereby an onboard device temperature adjusting apparatus having a simple configuration can be provided at low cost.</p> |
