How Absorption Chillers Work - EnergyLink

Apr 04, 2019 The cooling tower pipe has a lower air pressure than the condenser. Thus, the vapor becomes water again as the air pressure decreases. The cold water then goes into the evaporator and waits to be mixed with the lithium bromide in the absorber again. In short, the absorption chiller chills water via sudden change of pressure.
