The current thesis proposed the integration of air conditioners that exhaust heat with solar energy to enhance the overall efficiency of thermal energy conversion. The analysis of thermal storage tanks of different volumes revealed that a two-ton air conditioner operating for an hour produced double energy than normal sunshine for a day. With thermal storage tanks of fixed volume, the integration of air conditioners of different tons with solar energy indicated that air conditioners of less tons produced faster and more efficient energy conversion. Therefore, the current thesis proposed that the modification of condenser in domestic air conditioner into water-cooled condenser not only enhanced the energy efficiency of air conditioners but also increased hot water supplies since hot water from air conditioners could be integrated into solar water heaters. By doing so, energy conservation and carbon reduction could be achieved.

The Given

The performance of one ton of refrigeration window air conditioner working with R-22 and retrofitted with eco friendly alternative refrigerant R-407C is experimentally investigated An internal heat exchanger is also added to the same air conditioner to provide liquid overfeeding operation. When retrofitting the R-22 system with R-407C, the coefficient of performance is found to drop by 7.28%, however when internal heat exchanger is included the performance is improved. It is observed that the inclusion of internal heat exchanger has increased the coefficient of performance by 5.86% when running on R-22 and 6.18% when running on R-407C, under the given conditions.
