Abstracts: This project focuses on the construction of a three fluid gas absorption refrigeration unit, intended to operate in a environment, with a compartment temperature less than environment. Gas absorption systems, unlike vapour-compression systems, use a heat source to facilitate refrigeration. Three fluid gas absorption refrigerators use no electricity and no moving parts, such as pumps and compressors, and operate at a single system pressure. Unlike the vapour-compression cycle, which utilizes pressure gains and drops to produce refrigeration, the three fluid gas absorption cycle uses the principle of partial pressure between two fluids to create the cooling effect. Extensive analysis of the thermodynamics, heat transfer, and chemical properties of a three fluid gas absorption system was conducted to design and construct the structural model shown in the report. This model was pressure tested for structural integrity and leakage and a safety analysis of the fluids involved was undertaken to insure proper functionality when the gases are introduced.
