Temperature adjusting device

A temperature adjusting device comprising:

• an evaporation-side target-object heat exchanger in which a first heat medium flows to exchange heat with an evaporation-side target object;
• a refrigeration cycle device that includes a condenser configured to condense a high-pressure refrigerant discharged from a compressor that compresses and discharges a refrigerant, and an evaporator configured to evaporate a low-pressure refrigerant pressure reduced in a pressure reducing portion that reduces a pressure of the high-pressure refrigerant;
• a condensing-side heat exchanger that is thermally connected to the condenser and exchanges heat between a second heat medium and the high-pressure refrigerant;
• a first heat exchanger configured to exchange heat between the first heat medium flowing out of the evaporation-side target-object heat exchanger and outside air;
• a second heat exchanger configured to exchange heat between the second heat medium flowing out of the condensing-side heat exchanger and the outside air;
• an evaporation-side heat exchanger thermally connected to the evaporator and exchanges heat between the first heat medium and the low-pressure refrigerant;
• a first heat medium circuit that circulates the first heat medium;
• a second heat medium circuit that circulates the second heat medium;
• and
• a switching unit configured to switch circuit configurations of the first heat medium circuit, wherein
• the first heat exchanger exchanges heat between the first heat medium flowing out of the evaporation-side target-object heat exchanger and the outside air;
• the second heat exchanger exchanges heat between the second heat medium flowing out of the condensing-side heat exchanger and at least part of the outside air that has passed through the first heat exchanger,
• the first heat medium circuit and the second heat medium circuit are configured as independent heat medium circuits in which the first heat medium is not mixed with the second heat medium, and
• the switching unit is configured to switch a circuit configuration in which the first heat medium flowing out of the first heat exchanger flows into the evaporation-side target-object heat exchanger and a circuit configuration in which the first heat medium flowing out of the first heat exchanger flows into the evaporation-side heat exchanger.
