Abstract

The present study has been conducted to an analysis of two stage refrigeration cycle with alternative refrigerant R410A. In the analysis, single stage cycle (R22 and R410A) compared to COP changing with supercooling degree. Secondly, two stage refrigeration cycle is investigated to the existence of intercooler or supercooler. At results, supercooler contributes to the increase of cooling capacity and the decrease of COP.
