<p>PROBLEM TO BE SOLVED: To circulate a low-temperature heat medium in a heating part to properly perform cooling and circulate a high-temperature heat medium in the heat radiation part to properly perform heating, with a more simple constitution of circulation of the heat medium to the heating part and circulation of the heat medium to the heat radiation part.SOLUTION: Circulation state control means, when a heating part 20 is in an actuation state, in a heat medium circulation circuit C1, mixes a heat medium taken out from the lower part of a heat storage tank 10 and heated by the heating part 20 with a heat medium taken out from the upper part of the heat storage tank 10 to circulate mixture to a heat radiation part 30, and when only the heat radiation part 30 is in the actuation state, circulates the heat medium taken out from the upper part of the heat storage tank 10 to the heat radiation part 30.</p> |
