소형 암모니아 흡수식 냉난방기의 냉방성능 특성

Refrigeration plants using absorption principles have been around for many years with initial development taking place over 100 years ago. Although the majority of absorption cycles are based on water-LiBr cycle, many applications exist where ammoniawater can be used, especially where lower temperatures are desirable. In both systems water is used as working fluid, but in quite different ways: as a solvent for the ammonia system, and as refrigerant for the lithium bromide system. This explains that the lithium bromide absorption system is strictly limited to evaporation temperatures above 0℃. The main industrial applications for refrigeration are in the temperature range below 0℃, the field for the binary system ammonia-water.
