A temperature setting unit is operated to set a desired temperature. An indoor temperature detector detects an indoor temperature. A timer is operated to set an operation start time. An indoor unit includes at least an indoor heat exchanger, an air duct associated with the indoor heat exchanger, a heat radiation member located in the air duct, a heat accumulator thermally coupled to the heat radiation member, and an electric heater for selectively supplying heat to the heat accumulator. An outdoor unit includes at least a compressor for cooperating with the indoor heat exchanger to constitute a heat pump refrigeration cycle for heating operation, and an outdoor exchanger. A controller outputs a first control signal for preheating the electric heater a predetermined period of time before operation start time by counting preset data of the operation start time from the timer, and a second control signal for setting the heat pump refrigeration cycle in a drive state at the operation start time. The controller controls the drive state on the basis of desired temperature data set by the temperature setting unit and indoor temperature data detected by the indoor temperature detector, thereby maintaining an indoor temperature at the desired temperature.
