THE DESIGN AND TECHNICAL REVIEW OF AN ABSORPTION COOLING CYCLE USING SOLAR ENERGY

In the present study, a solar system is designed for a residential building with an infrastructure of 1200 square meters and 1050 square meters of ventilated useful space in Haji-Abad city. This system is suitable for integrating solar and cooling systems. It is a single-effect absorption chiller with hot water supply and drainpipe collector. Natural gas consumption in ordinary absorption chiller was 44.4 cubic meters per hour. After calculating the thermal and the combustibility value of gas, natural gas consumption in solar absorption chiller was 29.7 cubic meters per hour less than the initial state, which is very economical. The functioning period of this system has been considered for 9 months. The results show that the initial costs are low and the running costs are high in ordinary absorption chillers while the reverse holds true for solar absorption chillers. This can be a new option of using absorption chillers with a capacity over 70 tons of refrigeration in absorption cycles that use solar energy
