分析了电动式和吸收式冷水机组的能耗及其对环境的影响，指出与电动式冷水机组相比，蒸汽型、热水型吸收式冷机的一次能耗约为２～３倍，ＣＯ２、ＳＯ２排放量为１．６～３．５倍；以自备或区域锅炉房供热时，其烟尘排放量为电动式的１３～１５倍；各种类型吸收式冷机的温室效应均比电动式严重；直燃机对大气的污染较轻。
Analyzed the energy consumption of electric and absorption chillers and their impact on the environment, and pointed out that compared with electric chillers, the primary energy consumption of steam-type and hot-water absorption coolers is about 2-3 times, CO2 , SO2 emissions are 1.6-3.5 times; when self-prepared or regional boiler room heating, the dust emissions are 13-15 times that of the electric type; the greenhouse effect of all types of absorption cooler is better than Electric type serious; direct-fired machine pollution to the atmosphere is lighter.
