Gas-fired absorption chiller

Gas-fired absorption chiller

Mechanical equipment that is used to generate chilled water for cooling of buildings. Conventional chillers use electricity as the energy source, whereas gas-fired absorption chillers use clean-burning natural gas. While conventional chillers have a compressor and use refrigerants to produce cooling, absorption chillers contain an absorber, generator, pump, and heat exchanger, and they do not use ozone-depleting substances. The absorption cycle uses environmentally friendly working fluids, namely, water (refrigerant) and lithium bromide (absorbent). Some absorption chillers use ammonia as the refrigerant and water as the absorbent.
