Absorption chillers use heat in place of electricity for cooling. With the move toward distributed power, the phase‑out of CFC/HCFC refrigerants, and growing concern about global warming, absorption cooling has emerged as a cost‑effective and environmentally considerate alternative to electricity‑driven compression chillers. Applicable to industrial process chilling and commercial air‑conditioning, solutions can be customized to site requirements. These machines can run on a variety of heat sources: steam, hot water, liquid/gaseous fuels, exhaust gases, or a combination.
