摘　　要： 分析了常用空调冷/热源(电制冷/热泵、溴化锂机组、燃气机机组和燃气锅炉)和生活热水(燃气和电热水器)的一次能源利用率,认为可在电力有保障的情况下优先考虑使用电动机组作为空调的冷热源;对电网峰谷差比较大而燃气充足的地区可采用燃气机组作为空调的冷热源;而单效溴化锂机组仅用于有余热利用的场所;生活热水应使用燃气热水器;不提倡使用电锅炉作空调的热源或电热水器提供生活热水。 Primary energy rate is used to evaluate the performance of air conditioning heat and cold sources （refrigerator/heat pump driven by electrical power, LiBr absorption unit, gas air conditioning unit and gas boiler） and hot water. The results show that air conditioning unit driven by electrical power is chosen first where electrical power is enough. Gas air conditioning unit can be used to reduce the peak electric demand where the peak of electricity web is great, and gas is enough. Single effect LiBr absorption unit is used only where waste heat can be used. Gas heater should be used to supply hying hot water. Electric boiler is not encouraged to use as air conditioning heat sources. Electric heater is also not encouraged to use to apply living hot water.

关 键 词： 空调机组 冷热源 能源利用率
