Solar Energy is one of the most attractive
and well-known source among all known renewable energy
resources therefore, solar assisted air-conditioning systems
attract researcher’s interests. Solar cooling technology is
environment friendly and contributes to a significant
decrease of the CO2 emissions which cause the greenhouse
effect and thus helpful in reduction of Ozone depletion.
According to the operating temperature of driving thermal
source, single – effect Li Br/H2O absorption chillers have
the advantage of being powered by ordinary flat-plate or
evacuated tube solar collectors available in the market.
The objective of this work is to develop an experimental rig
based on the simulation results of an optimized - single - effect absorption air conditioning system using LiBr/H2O
solution as working fluid assisted by solar thermal energy.
Detailed mathematical design is prepared by applying
energy and mass balances on each component. Afterwards
parametric analysis is performed on EES to determine the
effects of evaporator temperature, condenser temperature,
and generator temperature on COP of the system. Then
simulation based optimization of the proposed design is
conducted on dynamic simulation program TRNSYS and
GenOpt, based on local weather profile of Taxila. The
results of the simulation of the absorption chiller indicate a
thermal performance coefficient, COP of 0.756.The results
of the simulation are validated by the locally fabricated
experimental rig
