THERMAL STORAGE DEVICE AND AIR CONDITIONER PROVIDED WITH THERMAL STORAGE DEVICE

摘要

A heat storage device is disposed around a compressor to store heat generated by the compressor and includes a heat storage material for storing heat generated by the compressor, a heat storage tank for accommodating the heat storage material therein, and a heat storage heat exchanger accommodated in the heat storage tank. The heat storage tank has a bottom portion in contact with the heat storage material and the bottom portion has a horizontal cross-sectional area smaller than that of the heat storage tank in the vicinity of a liquid surface of the heat storage material. This configuration allows heat generated by the compressor to efficiently spread throughout the heat storage material within the heat storage tank.
