Peltier Effect Based Solar Powered Air Conditioning System

Abstract

This paper demonstrates an environmental friendly methodology for implementing an air conditioning or refrigeration system. In particular, the cooler does not deplete the earth's limited fossil fuel reserves nor does it harm the global environment either by depleting stratospheric ozone or by contributing to global warming through the emission of greenhouse gases. The electrical energy input needed to power the cooler is supplied from a solar panel. The air-conditioning based on thermoelectricity may play an important role despite a lower cooling performance compared with gas compression cycles. With the usual arrangement of a heat sink on each side of the Peltier device, air would be directed away on the hot side and forward on the cool side, thus cooling the surrounding area. The proposed model is verified using appropriated hardware, where the results are found to be satisfactory.
