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. Keywords Peltier effect semiconductor air conditioner solar energy. 1. INTRODUCTION Utilization of solar energy includes two aspects Thermal use and power generation. General solar thermal projects such as heat collecting supply of heating water etc. are not fully consistent with the available solar energy on demand. In cold weather the heat provided by the sun is often inadequate. While in the hot summer weather a large proportion of power energy may be consumed in the cooling operation. Solar cooling is highlighted in some advantages 1 Well match to the seasons that is the hotter the weather the stronger the solar radiation the greater the cooling capacity of the system 2 solar cooling system can be effective in combining .
