PROBLEM TO BE SOLVED: To surely reduce power consumption of a whole air conditioner in a heat storage type air conditioner including a heat storage circuit.SOLUTION: A heat storage type air conditioner (10) performs a utilization cooling operation for cooling indoor air by, in an indoor heat exchanger (27), evaporating a refrigerant which is cooled in a heat exchanger (37) for heat storage after being condensed in an outdoor heat exchanger (22). In the case where specific gravity of a heat storage medium in a solid state is larger than specific gravity of the heat storage medium in a liquid state, and, in a heat storage tank (62), the heat storage medium flows out from an outflow pipe (56) arranged above an inflow pipe (55), an operation control unit (100) controls a rotational speed of a pump (63) according to a cooling load indoors during the utilization cooling operation.SELECTED DRAWING: Figure 6 |
