Abstract
An air conditioning system comprising a refrigerant circuit. A thermal storage device is arranged in the refrigerant circuit and can store heat and utilize the stored heat to increase heating capacity at the time of kickoff of heating. A temperature detector detects a temperature at a thermal storage portion of a thermal storage and radiating heat exchanger which is housed in the thermal storage device. A counter counts a thermal storage operation period required for the temperature detected at the thermal storage portion to achieve a predetermined value, outputs a signal indicative of stopping a thermal storage operation when the detected temperature has achieved the predetermined value, counts the lapse of a predetermined thermal storage operation stoppage period after stop of the thermal storage operation, and outputs a signal indicative of starting the thermal storage operation when a predetermined thermal storage operation stoppage time has passed. A controller controls comparing the counted thermal storage operation period with a present value, and determines the next thermal storage operation stoppage period, depending on the length of the counted thermal storage operation period.
