Abstract
The absorption chiller-heater doesn't require Freon gas as refrigerant and is driven by the clean energy, natural gas. Therefore it has been widely used in Japan. In particular, after the Great East Earthquake, it is getting a lot of attention in terms of electricity shortage and the promotion of effective utilization of renewable energy like solar energy. This paper describes the high annual performance model, the triple effect chiller-heater, and the solar cooling system as latest technology in the absorption chiller-heater.
