上海的各种空调建筑中,空调能耗约占建筑总能耗的45％左右,照明能耗约占1/3,其它22％为电梯、电脑、给排水等能耗。而建筑中的空调冷热源设备又是五花八门,为了节约空调能耗,对各种空调冷热源的一次能耗水平进行了比较,采用1kW相当于2450kcal/h换算成一次能源,将各种空调冷热源设备的一次能源效率列于下表,该表可供空调设计的工程技术人员和使用单位的管理技术人员选择空调冷热源设备参考。
In various air-conditioned buildings in Shanghai, the air-conditioning energy consumption accounts for about 45% of the total building energy consumption, lighting energy consumption accounts for about 1/3, and the other 22% are for elevators, computers, water supply and drainage, and other energy consumption. The air-conditioning cooling and heating equipment in the building is varied, in order to save air-conditioning energy consumption, a comparison of the energy consumption levels of various air conditioning cold and heat sources, using 1kW equivalent to 2450kcal / h converted into primary energy, will all The primary energy efficiency of the air-conditioning cooling and heating source equipment is listed in the following table. This table can be used by air-conditioning design engineers and management personnel of the use unit to select the air-conditioning cooling and heating source equipment reference.
