Description
Summary:Among the renewable energy sources, a wind turbine is the most commonly used due to its low cost, ease of maintenance and operation, and commercial acceptance. Heat pump systems are a hopeful technology used for heating purposes that achieve exceptionally high efficiencies compared to burning fossil fuels. The overall goal of this research is to develop an intelligent energy system, where energy is reaped from the wind turbine and the generated energy is used to drive a heat pump that produces hot water for various purposes. The output power from the wind turbine was computed by utilizing the MATLAB program for NACA0024 at two angles of attack, namely 5o, and 10o. Further, the coefficient of performance (COP) of the heat pump system was determined based on mathematical models running by Engineering Equation Solver (EES) program under different condenser temperatures such as 30 °C, 35 °C, 40 °C, 45 °C, and 50 °C with 5 °C evaporator temperature. The COP of the heat pump system was studied at four different wind speeds, namely 6 m/s, 7 m/s, 8 m/s, and 9 m/s. The results show that the maximum COP at 30 °C condenser temperature and 5 °C evaporator temperature was 4.1. Moreover, the minimum value of COP was 2.5 at 50 °C condenser temperature with the same evaporator temperature.
