Vapor Absorption Systems

Vapor Absorption Systems

Vapor Absorption Refrigeration Systems (VARS) offer a thermally-driven alternative to mechanical refrigeration systems, effectively using low-grade thermal energy. Key components include absorbers, generators, and condensers that work together in a cycle to create refrigeration. These systems highlight significant advantages, such as reduced maintenance and suitability for diverse applications, including industrial cooling and solar-powered refrigeration.
