How Absorption Chillers Work - EnergyLink

Apr 03, 2019· In short, the absorption chiller chills water via sudden change of pressure. When the water heats up in the generator, the air pressure is high. Water releases the heat and becomes vapor. Then, a pipe leads the vapor to the evaporator, where the air pressure is low. The vapor will then cool down and become cold water again immediately.
