摘要: Abstract Adsorption refrigeration systems are commercially developed due to the need of replacing conventional which utilise environmentally harmful refrigerants and consume high grade electrical power. This paper presents key equations necessary for developing a novel empirical lumped analytical simulation model commercial 450 kW two-bed silica gel/water adsorption chiller incorporating mass heat recovery schemes. The governing were solved using MATLAB® platform integrated with REFPROP® determine working fluids thermo-physical properties. predicted performance within acceptable tolerance hence it was used as an evaluation optimisation tool. investigating effect changing fin spacing on where from its design value minimum permissible increased cooling capacity by 3.0% but decreased COP 2.3%. Furthermore, generation temperature lift feasibility load control tool will be discussed. Genetic Algorithm optimum cycle time corresponding maximum capacity, new 8.3%.
