Air conditioning cold and heat source system design and energy saving effect of Guolin Hotel

Presents the design of the system in the three modes of direct heating by the electric boiler, heating by the heat storage water tank and simultaneously heating and heat storing of the electric boiler through the interdependence movement among three heat storage water tanks, motorized two-way valve and temperature controlled motorized three-way valve. The statistic result of power consumption and cost of the hotel indicates that this design can largely save operating expense and bring about obvious economic efficiency in the presence of the time sharing electric power pricing programme in Beijing.
