ABSTRACT

Aiming to compare the cooling effect, two types of solar-powered semiconductor air-conditioning devices were designed in different structures. According to the cooling load in an experimental room, the solar panels and battery capacity were determined for the development of a test system. In the same working condition, a comparison test was carried out to examine the cooling performance. Experimental results showed that the design of dual water-cooled cooling unit presented a higher ratio of energy efficiency, with its maximum value of 1.08. By observing the experimental data of the prototype, its comparative economic evaluation results indicated that the annualized cost of solar semiconductor airconditioning was app. 2.7 times that of air-conditioning made from an ordinary compressor.
