PROBLEM TO BE SOLVED: To provide an accumulator utilizing the latent heat, wherein COP of a heat source device is improved, by setting an outlet temperature of the heat source device in radiating operation, to high temperatures or low temperatures before achievement with respect to a set temperature of an inlet of a heat exchanger, and the stability and controllability of a supply temperature to heat load is improved by a thermal buffer function of a heat storage tank. SOLUTION: In a cold accumulation mode, a heat transfer medium from a cold source device 20 is joined to a downstream side of a circulation pipe conduit 25b after accumulating the cold from a circulation pipe conduit 25a to a thermal storage tank 1, and then returned to the cold source device 20 again. In a cold heat radiating mode, the heat transfer medium is passed through the thermal storage tank 1 from the circulation pipe conduit 25a at a downstream of the cold source device 20, joined to the downstream side of the circulation pipe conduit 25a again through a heat transfer pipe 23b', then passed through a heat exchanger 28 at a side of an apparatus 26 using the cold or a bypass pipe 27, and returned to the thermal storage tank 1 again through a bypass pipe 24 at the cold source device 20 side or between the upstream and downstream. The thermal storage tank 1 is connected to the downstream side of the cold source device 20 in series. COPYRIGHT: (C)2005,JPO&NCIPI |
