ABSTRACT:
A central heat source system is used as the method of air-conditioning individual spaces, and warm water in the range of 15.degree. to 25.degree. C. is produced by a warm water generator having a heating device and a cooling device. The warm water is circulated among the warm water generator and a plurality of heat pumps connected thereto. In a certain room, the heat pump can be operated to perform cooling by using the warm water as cooling water, while in another room the heat pump can be operated to perform heating by using the warm water as heat source water. In addition, when the heated warm water used for cooling and the cooled warm water used for heating are returned to the warm water generator and are mixed therein, the thermal energy gained or lost by the respective warm water can be offset with each other, so that it is possible to reduce the amount of energy necessary for maintaining the warm water at 15.degree. to 25.degree. C., thereby making it possible to effect energy-saving in air-conditioning.
