The case study of building cooling by thermoelectric cooler using solar energy resources

In this study, the passive cooling system consisting of photovoltaic panel and thermoelectric cooler as a source of electricity and cooling equipment has been designed and evaluated. The result of this study was used in system design consist of thermoelectric cooler, photovoltaic panel and the room which is self-sufficient in terms of cooling energy supply. Thus, first, the energy demand for the room is calculated, and then in order to evaluate the maximum performance of the thermoelectric cooler, two methods were obtained: 1) maximum cooling power and 2) maximum coefficient of performance (COP). In the calculations done for maximum cooling power method, the cooling power and coefficient of performance, were 58.41W and 0.44056, respectively; and for maximum coefficient of performance method, the cooling power and coefficient of performance were 15.5W and 1.64, respectively. To access the best performance of thermoelectric coolers in both maximum cooling power and coefficient of performance simultaneously, by selecting the arrangement (3´8), both the cooling peak load and the high performance coefficient we will achieve.
