This indicates the higher the temperature difference between the hot and cold streams, the more exergy destruction occurs. In order to reduce the amount of exergy destroyed, it is desirable to keep the temperature difference to a minimum. Two approaches can be used to achieve this goal. One is to increase the heat transfer area, which will reduce the required temperature difference for a given amount of heat load. The other is to keep or even reduce the heat transfer area, but significantly increase the heat transfer coefficient. The first approach is achievable in stationary applications where size and weight are not an issue. It becomes impractical for portable applications where component size and weight significantly impact the overall design objectives. In this case, the alternate approach may be realized by using microchannel technology to enhance heat transfer. Several past studies [26 -31] have shown the advantages of using microchannel heat exchangers, specifically for heating and cooling applications. They can achieve both goals of reducing exergy destruction, and minimizing size and weight. During this study microchannel heat transfer components were designed for all heat transfer processes, including the boiler, power recuperator, condensers and evaporator. In addition, scroll technology has been used to build the expander and compressor. Their inherent high isentropic efficiency at their intrinsic pressure ratio minimizes the entropy generation during the expansion and compression processes. The 2nd law efficiency of the cycle can be expressed in different ways. However, the more straightforward approach is to compare the actual cycle performance to the ideal (Carnot) cycle performance. Expressions of 2nd law efficiency for both the power and cooling cycles are given as, Power cycle: Cooling cycle: *,++ - U>9 R< B5M,BA0S *,++ - _W7 HB5M,BA0 6 18 HM44@,BA0 (2.17) (2.18) In addition, the 2nd law efficiency of the power cycle can be determined by comparing the net work produced by the current power cycle with the reversible work produced by Carnot cycle.
