Solar Air-Conditioning System Using Single-Double Effect Combined Absorption Chiller

Abstract:

We developed a single-double effect combined absorption chiller for "Solar air-conditioning system" . This chiller is composed of a highly-efficient gas absorption chiller as a main machine which are equipped with a solar heat recovery unit comprising a heat recovery heat exchanger and special condenser. It enables low temp. solar hot water at 75°C under operation at the cooling rating of load factor: 100%. And we constructed the demonstration plant in Japan. We confirmed that the solar heat priority usage function and gas-based backup function operate properly and overall system functions normally. In summer, fuel gas reduction by 10% could be achieved and the results as estimated were obtained.
