This paper discuss about structure modification method of the reciprocating compressor to reduce its vibration and noise in small refrigeration system. The structure modification is applied using analytic FE models and then applying suggested Component Mode Synthesis(CMS) algorithms. The efficient CMS algorithms to a compressor's fixed base design problem are analytically tried and verified from some experiments.

A series of field tests on hybrid desiccant cooling systems were conducted in July-August, 2013. The temperature and humidity of the supply and return air, power, and heat consumption were monitored and transferred in real time through the Internet. The performance parameters of the cooling system, namely, cooling capacity and COP (coefficient of performance), were evaluated from the measured data and their variations under outdoor conditions was analyzed. It was found that with increase in the outdoor temperature, the total energy decreases and cooling capacity increases whereas the latter decreases with increase in the outdoor humidity. The COP was also found to increase with the increase in outdoor temperature.
