Harnessing Waste Heat from Low Temperature Heat Source

This Book provides a thorough investigation of Vapour Absorption Refrigeration Systems (VARS), covering multiple crucial elements throughout six chapters. Readers are introduced to the various types of absorbers used in Variable Amplitude Refrigeration Systems (VARS). The chapter also provides a detailed explanation of the thermodynamic and thermo-physical properties of different combinations of refrigerants and absorbents. The book provides a comprehensive literature review that examines the impact of operating temperatures, the efficiency of components, and the studies on heat and mass transfer of absorbers. The comparative analysis of VARS (Vapour Absorption Refrigeration Systems) based on HFC (Hydrofluorocarbon) and HCFC (Hydrochlorofluorocarbon) revealed that the R134a-DMAC combination and the falling film absorption mode are highly promising for absorbers.
