Abstract
The system improves thermal efficiency by appropriately switching the amount of heat transfer fluid circulated when operating in heater mode. [Solution] The heat transfer medium circuit 20 includes an indoor air conditioning unit 25, a first pump 21 that pumps the heat transfer medium HM that has passed through the condenser 12, and a second pump 22 that pumps the heat transfer medium HM that has passed through the evaporator 14. The control unit 30 provides a temperature control system 100 that switches between a first heater mode, in which either the first pump 21 or the second pump 22 is operated to combine the heat transfer medium HM that has passed through the condenser 12 and the heat transfer medium HM that has passed through the evaporator 14 via a connecting passage L5 and supply it to the indoor air conditioning unit 25, and a second heater mode, in which both the first pump 21 and the second pump 22 are operated to combine the heat transfer medium HM that has passed through the condenser 12 and the heat transfer medium HM that has passed through the evaporator 14 via a three-way valve 29 and supply it to the indoor air conditioning unit 25.
