"WebThis absorption cooling cycle relies on three basic principles: When a liquid is heated it boils (vaporizes) and when a gas is cooled it condenses. Lowering the pressure above a liquid reduces its boiling point. Heat flows from warmer to cooler surfaces. The process of absorption cooling is dependent on a thermochemical ‘compressor’.
