Abstract :In the present study, cooling of a duplex house placed in Isparta province by using solar-powered single effect absorption refrigeration system, which uses water-lithium bromide insert ignore into journalissuearticles values(H2O-LiBr); mixture, was evaluated in details. Firstly, the cooling load of the house was determined as 19.34 kW. In order to provide the cooling load of the house insert ignore into journalissuearticles values(19.34 kW);, the heat required for the generator was calculated as 26.76 kW, and the required collector surface area was determined by considering different types of collectors insert ignore into journalissuearticles values(flat plate and vacuum tube); to meet this heat capacity. In order to provide the cooling load of the house, the required surface area for the vacuum tube collectors was calculated as 10.32 m2 while it was found as 25.95 m2 for the flat plate collectors. It was concluded that the usage of vacuum tube collector with 57.9% efficiency is more appropriate since the required collector surface area is 15,63 m2 less than the required collector surface area for flat plate collector.
