This paper addresses the potential of integrating a hybrid solar powered cooling system with ice storage for the purpose of space cooling in residential and ofice buildings.
Indeed, the use of solar cooling technologies has the potential for primary energy savings in the range of 21–70% [ 4 ]. One of the first solar active cooling systems was a solar absorption air conditioner of industrial-scale constructed and tested in 1976 in the USA [ 5 ].
While solar cooling can be provided without any storage capacity, our design is intended to make use of the high levels of sunlight during the peak irradiation time during the day in order to provide cooling during the subsequent period of peak cooling demand. Therefore, our design does utilize a method for storing energy for cooling as needed.
Therefore, our design does utilize a method for storing energy for cooling as needed. The combined air conditioning and thermal storage system is intended as a technology to increase the effectiveness of solar photovoltaic energy use.
However, as the performance of an absorption chiller and the conditioned space are mutually influenced by each other, a software capable of simulating the conditioned space in conjunction with the solar-powered cooling system was required. The commercial software TRNSYS was selected.
5. CONCLUSION The solar powered ice thermal storage system is effective for some circumstances. The model is useful for evaluating whether the system would work and what its cost and savings would be for each situation. 6. FUTURE WORK
