IMPROVEMENT OF THERMAL PERFORMANCE OF A COUPLING HOT WATER- DRIVEN AND GAS FIRED-DRIVEN ABSORPTION AIR CONDITIONING SYSTEM BY BOTH USING SOLAR ENERGY AND GAS ENGINE COOLING WATER

抄録

This paper presents the thermal evaluation results on a solar-assisted coupling hot water-driven and gas fired-driven absorption air conditioning system at experimental apartment housing NEXT21. The coupling air conditioning system consist of hot water driven single effect absorption refrigerator of 31.3 kW rated cooling capacity and gas-fired double effect absorption chiller of 105 kW rated cooling capacity. Performances of both each two types of absorption refrigerator and whole absorption air conditioning system were evaluated by COP and compared each other.
