Exergy and exergoenvironmental assessment of a geothermal heat pump and a wind power turbine hybrid system in Shanghai, China

Abstract Geothermal heat pumps are one of the most growing and cost-effective renewable energy technologies based on temperature difference between ground environment. In cold seasons, inside soil or water is higher than ambient temperature. Therefore, pump used to extract warm into house any other controlled space. summer, air water. This again cool paper examines exergy assessments a hybrid system in Shanghai, China, that employs geothermal with an economizer for winter heating wind turbine provide clean electricity. The complete set procedures, as well every component aspect system, have all been carefully examined. pump's coefficient performance 3.916, its net power output 22.03 kW, overall efficiency 77.2%, 25.49%.
