Present study deals with thermal analysis of absorption refrigeration system (ARS) and generator-absorber heat exchanger (GAX) based absorption refrigeration system by using green composite like aqua-ammonia. Evaporator temperature is 0°C for cold storage application, condenser temperature is 50°C as per Indian weather condition, mass stream rate of strong solution through the pump is 1 kg/s, and effectiveness of solution heat exchanger and refrigerant heat exchanger is 0.7 considered for present comparative study. This study is carried out to examine the variation in COP of both types of absorption refrigeration system for various functioning factors. Outcomes indicate GAX based ARS provides superior performance than that of conventional ARS for various operating parameters. It is concluded that COP of both the systems are higher at higher degasing range, lower pressure ratio and higher value of effectiveness of refrigerant heat exchanger (RHE). It can be also concluded that generator temperature is higher at higher value of degasing range and pressure ratio for the fixed value of all other operating parameters

Keywords: Composite material, Absorption refrigeration, COP, degasing range, GAX, pressure ratio, thermal analysis.
