Design, Construction and Testing of Hybrid Photovoltaic Integrated Greenhouse Dryer

P. Barnwal and Arvind Tiwari

Abstract: In this study, a hybrid Photovoltaic (PV) integrated greenhouse (roof type even span) dryer has been designed and constructed at Solar Energy Park, Indian Institute of Technology (IIT), New Delhi, India. The testing of the proposed hybrid dryer (without load) has been carried out by using the thermal loss efficiency factor. The dryer has floor area of 2.50x2.60 m with 1.80 m central height and 1.05 m side walls height from ground. The roof has slope of 30 °. Two PV modules (glass to glass) were used in its construction for thermal heating of greenhouse environment and to provide electrical power to operate a DC fan under forced mode condition. The experiments have been conducted under natural and forced mode operation without load. It has been observed that the direct thermal loss efficiency under forced mode is higher as expected for crop drying. The coefficient of diffusion under natural mode has also been determined.
