Abstract
An air conditioning system including at least one water-cooling type air conditioning unit, a heat pump chilling unit, an ancillary heat exchanger in said water-cooling type air conditioning unit, and a cold and heat accumulating tank divided into two tank sections differing from each other in volume and the temperature of water contained therein. In a cooling mode, cold water of relatively high temperature and cold water of relatively low temperature are accumulated by operating the heat pump chilling unit at night, and when a normal heating operation is performed, the cold water of relatively high temperature is used as cooling water for a condenser of the water-cooling type air conditioning unit and when the water-cooling type air conditioning unit is inoperable as when power failure occurs at peak load, the cold water of relatively low temperature is supplied to the ancillary heat exchanger to carry out cooling. In a heating mode, warm water of relatively high temperature and warm water of relatively low temperature are accumulated by operating the heat pump chilling unit at night, and at startup in a heating operation, the warm water of relatively high temperature is supplied …
