How do absorption chillers work?

The principle behind an absorption process is to separate and recombine to fluids (refrigerant and absorbent) to create a cooling effect. Usually, absorption chillers are either NH 3 -H 2 0 (ammonia-water) cycle or LiBr (Lithium bromide) cycle. In the first cycle, water acts as the absorbent while ammonia water solution acts as the refrigerant.
