1. An air conditioner, comprising:
a refrigerant circuit having an air heat exchanger which exchanges heat between a refrigerant and air; a thermal storage circuit having a thermal storage tank configured to store a thermal storage medium which turns into slurry when cooled, and a circulation pump provided to circulate the thermal storage medium; a thermal storage heat exchanger which is connected to the refrigerant circuit and to the thermal storage circuit, and exchanges heat between the refrigerant flowing in the refrigerant circuit and the thermal storage medium flowing in the thermal storage circuit; an auxiliary heat exchanger which is connected to the refrigerant circuit and to the thermal storage circuit, and exchanges heat between the refrigerant flowing in the refrigerant circuit and the thermal storage medium flowing in the thermal storage circuit; and a retention portion provided in the thermal storage circuit to retain crystals contained in the thermal storage medium, wherein the refrigerant circuit performs a cool storage operation in which the refrigerant is circulated such that the refrigerant which has been condensed in the air heat exchanger and passed through the auxiliary heat exchanger is evaporated in the thermal storage heat exchanger, and in the thermal storage circuit during the cool storage operation, the thermal storage medium is circulated such that the thermal storage medium having flowed out from an outlet of the thermal storage tank sequentially passes through the auxiliary heat exchanger, the retention portion, and the thermal storage heat exchanger and flows into an inlet of the thermal storage tank. |
