  • This study determined the thermal analysis of solar water heating system (SWHS) for Erbil
    city. SWHS is adorable system for receiving and saving energy. Solar energy is one of the
    most important sources of renewable energy and gets great useful energy. Erbil city is
    considered a suitable place to receive solar global irradiance energy, reasonable solar
    intensity is available during the year. The characteristics of the SWHS includes (flat plate
    solar collector, hot water storage tank unmixed fluid (reservoir) with heat exchangers,
    working fluid through the pipes and tubes, water pump system and loading zone that is
    greenhouse). This study describes the evaluation of the optimum performance and
    determine the parameters of SWHS for Erbil (36.19 N Latitude, 44 E Longitude) climate
    conditions during summer season, the installed system based on winter months and
    (collector tilt angle) to get the highest total solar insolation during winter. The results
    demonstrated the optimum performance of each parameter respectively for the (total global
    irradiance, outlet collector temperature, the optimum collector efficiency, the amount of
    useful heat gains from the working fluid (water) through the solar collectors and heat
    transfer rate for loading zone) from the solar water heating system has been investigated by
    experimentally study data. The results show that the optimum performance during the test
    duration is a global irradiance with 630 W/m2
    , outlet collector temperature is 69.5 ℃, the
    optimum value of collector efficiency 0.93, the amount of useful heat gains is 10.238 kW
    and heat transfer rate for loading zone 7.56162 kW. In addition, an exergy analysis the
    optimum exergy analysis for the flat plate solar collector is about 3.56kW, the optimum
    exergy analysis for the storage tank is about 3.56kW, the optimum exergy rate for loading
    zone is about 0.86kW, the exergy efficiency of the solar collector is about 7.3% with energy
    and exergy analysis is used to investigate system performance of the as shown results. The
    first law of thermodynamic and the second law of thermodynamic are used for that. Energy
    is calculated to measure the quantity but exergy is calculated to measure the quality of
    energy performance. Exergy is a period to get beneficial energy that can be get more useful
    VIII
    or suitable energy principle. In the solar energy system great significance has been placed
    on the expansion of active solar energy systems which involves the combination of several
    sub-systems: flat plate solar collectors, hot water storage tank with heat exchangers unmixed
    fluid, working fluid through the pipes or tubes and loading zone (greenhouse). The major
    component of the active close systems is the solar collector involves of flat plate solar
    collectors that is fixed on the top floor of Erbil Research Building Center of Kurdistan region
