Abstract EN

In this steady, modeling the thermal performance of one type of solar heating systems (closed system) that can be actually used in providing of hot water for the operation of absorption machine, by using one of the performance evaluating methods named as utilizability, f- chart method, in order to calculate the monthly solar fraction under different operating conditions include the use of different types of liquid solar collector with different solar collected areas.

The results that have been obtained from the steady proved that, the solar heating system that operate in areas with good abundant solar radiation during the summer can contribute significantly to the providing of thermal energy needed to run the absorption refrigerator especially by the use of these systems for solar collectors of high-quality performance with reasonable solar collected area.
