Using solar collector unit in a methanol-water vapor absorption cooling system under iraqi environmental conditions

Year: 2020

Type: article

Abstract: Testing, designing and fabricating a friendly vapor absorption cooling system was the main purpose of the present study using water and methanol as a working fluid. Various Iraqi environmental conditions (Hilla City) are the operating conditions under which the test rig experiment was performed. The temperature of the heat source, condenser, absorber and evaporator, is the involved property in the test calculations. The system is tested during June and July 2019. The results show that the COP of the absorption cooling system ranged from 0.22 to 0.38 while the range of temperature drop in evaporator is (9.8 °C–15.8 °C). Condensation and absorption temperatures are under 45 °C while the maximum temperature of the driving water was 85 °C. The results also show that the generator temperature had a great effect on the system performance.
