Performance Analysis of Solar Water Heating System in Erbil, Kurdistan Region of Iraq

Abstract

This study evaluates optimum performance and determines the parameters of solar water heating system (SWHS) of Erbil climate condition. The proposed SWHS is demonstrated through the efficiency of the flat plate solar collector, the capacity of the storage tank, the useful heat gains from the solar collectors, the outlet temperature of the solar collector and heat transfer rate for the loading zone. The results of the experimental case study showed that the outlet collector temperature is 69.5℃ with total global irradiance which is 631 W/m^2, while, the optimum value of collector efficiency is 0.93, the amount of useful heat gains is 10.238 kW and heat transfer rate for loading zone 7.56162 kW. The solar energy system is adorable system to provide the best products of heating and gets the best useful heat source as quantity as well as quality of energy in Erbil City in Kurdistan region of Iraq. Erbil governorate is a suitable place to receive and store energy, this system is installed in Erbil City at the Research Center of Kurdistan Region.
