Abstract
To avoid decline in the efficiency of a compressor at a low load, the thermal storage air conditioner has an operation controller which, if a rotational speed of the compressor is slowed down to a predetermined lower reference value in a simple cooling operation, switches operation of the thermal storage air conditioner from the simple cooling operation to a cooling and cold thermal energy storage operation to increase the rotational speed of the compressor. During the simple cooling operation refrigerant is condensed in the outdoor heat exchanger and evaporates in the indoor heat exchanger, and during a cooling and cold thermal energy storage operation the refrigerant is condensed in the outdoor heat exchanger, evaporates in the indoor heat exchanger, and the thermal storage medium in the thermal storage section is cooled by the refrigerant.
