Abstract
The ambient temperature is increasing as a consequence of global warming, requiring increased usage of air conditioning. The availability of solar energy and its use for air conditioning systems seems to be a possible solution in such circumstances to some degree. Thermodynamic study of a parabolic dish-based air conditioning system using a vapour absorption refrigeration cycle with H2O and LiBr as a working fluid is presented in this article. Exergy destruction in different components of the cooling arrangement, such as the generator, absorber, condenser, and evaporater, is assessed using thermodynamic modelling. According to the results, at 57 percent starting LiBr concentration, the generator has the greatest exergy loss rate of 2.535 kW, and at 45 percent initial LiBr concentration, the evaporator has the highest exergy loss rate of 3.375 kW. According to a financial study, the payback time for a PDC-based solar-powered air conditioner with a one-ton capacity is approximately six months.
