Embodiment Construction

[0026] The refrigeration cycle device of the present invention has: a compressor connected via refrigerant piping, an indoor heat exchanger, an expansion valve, and an outdoor heat exchanger; and a heat storage device having heat storage for accumulating heat generated by the compressor The heat storage tank for storing the material, and the heat storage heat exchanger for exchanging heat by using the heat stored in the heat storage material, and a controller for switching the first heat supply operation to the second heat supply operation, In the first heat supply operation, when the temperature of the heat storage material is below the specified temperature, the refrigerant discharged from the compressor passes through the indoor heat exchanger, expansion valve and outdoor heat exchanger; When the temperature of the material exceeds a predetermined temperature, the refrigerant discharged from the compressor is passed through the indoor heat exchanger and the thermal storage h...

Abstract

A refrigeration cycle device having a compressor (6), an indoor heat exchanger (16), an expansion valve (12), and an outdoor heat exchanger (14), which are connected through refrigerant piping, is provided with a heat storage device for storing heat generated by the compressor (6). The refrigeration cycle device is also provided with a controller which switches the operation of the device from first heating operation to second heating operation, the first heating operation being operation which, when the temperature of a heat storage material (36) contained in a heat storage tank (32) is lower than or equal to a predetermined temperature, causes the refrigerant discharged from the compressor (6) to pass through the indoor heat exchanger (16), the expansion valve (12), and the outdoor heat exchanger (14), the second heating operation being operation which, when the temperature of the heat storage material (36) exceeds the predetermined temperature, causes the refrigerant discharged from the compressor (6) to pass through the indoor heat exchanger (16) and a heat storage heat exchanger (34).

Description

technical field [0001] The present invention relates to a refrigeration cycle device including a heat storage tank for storing heat generated by a compressor, and a heat storage heat exchanger for exchanging heat by storing heat in the heat storage material. Background technique [0002] Conventionally, when the heat pump type air conditioner performs heating operation, when the outdoor heat exchanger is frosted, the four-way valve is switched from the heating cycle to the cooling cycle to perform defrosting. In this defrosting method, although the indoor fan is stopped, there is a disadvantage that the cooling feeling is lost due to the gradual release of cold air from the indoor unit. [0003] Therefore, a technique has been proposed in which a heat storage device is installed in a compressor installed in an outdoor unit and defrosting is performed using exhaust heat of the compressor stored in a heat storage tank during heating operation (for example, refer to Patent Docu...
