Data on the construction of a mathematical model to find the optimum heat exchanger's design in flat plate integrated collector storage solar water heating system which gives high thermal performance

ANSYS 13.0-Fluent software was used to solve the mathematical model to help find the optimum heat exchanger's design in flat plate integrated collector storage solar water heating system which gives high thermal performance. The outlet service water temperature is used as the measure of thermal performance. The effect of single and double row heat exchangers of different lengths and circular and elliptic cross-section pipes were investigated. The single row heat exchanger of 10.8 m length for the elliptical shape gave the highest service water outlet temperature and with low pumping power. This resulted in an increase in the thermal efficiency and a significant reduction in both the initial and the operating costs of the system.
