Combined Heat and Power Technology Fact Sheet: Absorption Chillers for CHP Systems
This fact sheet provides an overview of absorption chillers, which are used in commercial buildings and industrial plants to provide air conditioning, refrigeration, and process fluid cooling. There are two basic types of chiller cycles: vapor compression and sorption. Sorption chillers, which are available as either absorption or adsorption designs, are driven with thermal energy produced from a direct fired burner integrated with the chiller, or with thermal energy supplied indirectly to the chiller. Absorption chillers are often exhaust fired using thermal energy recovered from combined heat and power (CHP) prime movers (e.g., reciprocating engines, microturbines, and combustion turbines).
