Design and Evaluation of Small Wind Turbine Driven Earth to Air Heat Exchanger System for Heating Greenhouses in Izmir, Turkey

Abstract

For the first time, the simple EAHE and SWTS are analyzed from the thermodynamics viewpoint. The main goal of this study is to investigate the use of wind energy in greenhouse heating, which is modeled as hybrid earth to air heat exchanger (EAHE) and a small wind turbine system (SWTS) fixed at the Solar Energy Institute at Ege University, Izmir, Turkey. The study shows that 100 percent of the overall annual electricity usage of the model system (1970 kWh) can theoretically be achieved using SWTS. Under this result, developed passive solar preheating techniques combined with EAHE and SWTS might become economically better than conventional space heating / cooling systems used in agricultural and residential heating applications if such buildings are built in a location with a heavy winds resource
