Static analysis of a new scheme of two stage refrigeration cycle with the combination of FAM Z01 and FAM Z05 adsorbents

摘要

This paper presents static analyses of two stage adsorption cycle using FAM Z01 and FAM Z05 as the adsorbents. The conventional two stage system consists of four adsorbent beds. In contrast, in new scheme three beds were used assigning FAM Z01 and FAM Z05 combination for low and high pressure sides, respectively. The objectives of this study were to evaluate the performance of two stage cycle with the Z01 and Z05 combination of adsorbent pair, and to compare the performance with that of the conventional two stage cycle using Silica-gel. Static analysis based on Dühring diagram was employed to estimate the performances of specific cooing effect (SCE) and COP. It was found that the cycle with new combination gives SCE more than twice compared with the conventional Silica-gel–water system at the heat source temperature of 55?°C. The sensitivity analysis was also performed for optimal mass allocation to adsorbent beds.
