Chiller System Overview
Chillers use either a vapor-compression or absorption refrigerant cycle to cool a fluid for heat transfer. Both chiller types rely on three basic principles.
First - When a liquid is heated it vaporizes into a gas, and when a gas is cooled it condenses into a liquid
Second - Lowering the pressure above a liquid reduces its boiling point and increasing the pressure raises it
Third - Heat always flows from hot to cold.
