✦ Synopsis

A comparative thermodynamic study of the vapour absorption refrigeration systems (VARS) working with HFC134a and HCFC22 is presented. Due to its superior performance in HCFC22-based VARS, dimethyl acetamide is chosen as the solvent for both the refrigerants. It is observed that the HCFC22-based system yields significantly better COP than the HFC134a system. However, since the latter operates at lower pressures, the possibility exists to improve its COP by resorting to two-stage operation.

Generally in a vapour absorption refrigeration system (VARS) heat rejection temperatures at absorber (T,) and condenser (T,) are taken to be equal. However, different temperatures can exist when the cooling water flows in series through the two components. Under such situations, it is essential to k
