<P>PROBLEM TO BE SOLVED: To prevent complication of a constitution of an air conditioning system capable of storing both of hot heat and cold heat. <P>SOLUTION: In this air conditioning system 10, an outdoor unit 15 is connected to an indoor-side circuit 70 in which heat medium water on the utilization side is circulated. The outdoor unit 15 is provided with a refrigerant circuit 21. In the air conditioning system 10 during a cooling operation, a refrigerating cycle applying a heat exchanger 82 for heating as a condenser and a heat source side heat exchanger 23 as an evaporator, is performed in the refrigerant circuit 21. The heat medium water heated by a heat exchanger 82 for heating is introduced to an upper end section of the heat storage tank 37. Meanwhile, the heat medium water cooled by the heat source side heat exchanger 23 is partially introduced to a lower end section of the heat storage tank 37. In an internal space of the heat storage tank 37, the heat medium water of high temperature is stored at a part near the upper end, and the heat medium water of low temperature is stored at a part near the lower end. <P>COPYRIGHT: (C)2010,JPO&INPIT |
