ABSTRACT:
Described is a cooling/heating and hot water service system making use of a single heat source apparatus. The system includes a heat pump chiller designed to perform cyclic operations of heating and cooling, a heat exchanger unit having a heat exchanger adapted for supplying hot water and a water reservoir. The operating time zone for storage of hot water and the operating time zone for heating and cooling the room are set by a first program timer while the operating time zone for servicing hot water is set by a second program timer.
In this manner, the cooperating time zone of the system is divided into the operating time zone for storage of hot water and the operating time zone for heating and cooling, and the operation of storage of hot water is effected during the time of the day that heating or cooling of the room is unnecessary while servicing of hot water is effected during the time of operation of heating or cooling the room, with resultant improvement in the operating rate of the unit and more efficient heating/cooling and servicing of hot water.
