A Review of Working Fluid Combinations used in Diffusion Absorption Refrigeration Technologies

Abstract

A review of working fluids used in the diffusion absorption refrigeration technologies has been done in this work in order to determine the availability of viable working fluid that can give high cooling power while maintaining efficient system performance. In recent years the interest in diffusion absorption refrigeration has increased as a complementary refrigeration system that can utilize the low-grade heat for cooling. Many reviewers have studied in the work to review the viable working fluids that can be used in the system and concluding that there isanumber of fluids that show good working characteristics such as TFE-TEGDME, which has only been studied theoretically and is yet to be studied experimentally shows potential for being good working fluids. It can be said though diffusion absorption refrigeration is relatively new refrigeration technology as compared to conventionally used absorption system but the studies conducted till now shows its potential for being a very good alternative for low power refrigeration, a cooling system which is eco-friendly, noiseless and can use the low-grade heat which can make up for its low coefficient of performance.
