国林宾馆空调冷/热源系统设计与节能效果
Air conditioning cold and heat source system design and energy saving effect of Guolin Hotel
摘要：
介绍了该宾馆空调冷/热源系统的设计，该系统通过3个蓄热水罐与电动两通阀和温控电动三通调节阀的相互关联动作可实现电热锅炉直接供热、蓄热水罐供热、电热锅炉同时供热和蓄热三种运行工况。系统运行后的耗电量和电费统计结果表明，利用北京市分时电价政策，可以大幅减少运行费用，带来明显的经济效益。

Abstract：
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.
