    Since further energy saving for global environmental protection becomes a matter of urgency, the utilization of renewable energy is needed for realizing a low-carbon society. Especially, in Indonesia, according to the economic growth, the measures for the reduction of the greenhouse gas emissions and energy consumption are requested. Under these situations, a single-double effect combined absorption chiller for "Solar air-conditioning system" has been developed. This chiller is composed of a highly-efficient gas absorption chiller as the main machine which is equipped with a solar heat recovery unit comprising a heat recovery heat exchanger and special condenser. It enables low temperature solar hot water at 75 ºC under operation at the cooling rating of load factor: 100%. Solar air-conditioning system using single-double effect combined absorption chiller 239 kW was installed in the University of Indonesia Faculty of Engineering building located in Depok city in the vicinity of Jakarta, aiming to reduce greenhouse gas emissions. We have collected and analyzed data from this air-conditioning system to comprehend its performance and fuel gas reduction by around 20% could be achieved. The results are reported here.
