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 syst

In a double-effect series flow vapour absorption refrigeration system (VARS), an optimum value of the low-pressure generator temperature exists at which all the vapour generated at the high-pressure generator is condensed. At these conditions, a comparative study of the performance of VARS using env
## Abstract A prototype Stirling cycle refrigerator employing helium as a working fluid was investigated to determine whether a freonβfree machine was a viable alternative for the current household refrigerator. A displacerβtype or Ξ²βtype Stirling cycle machine of 100βW capacity was designed and te
The double-effect vapour absorption refrigeration system working with HFC134a as refrigerant and dimethyl acetamide as absorbent is analysed. Cooling coefficients of performance in the range of 0)5-0)9 could be obtained depending on the operating conditions. However, sub-zero temperatures are diffic
