Innovative Design of a Ventilated Modern Greenhouse Powered by PV/T Solar System

Abstract

In this paper, a modern design is proposed for ventilating and conditioning of greenhouse integrated thermal solar system in summer season in (33.3°N, 44.4 °E) Baghdad, Iraq with respect to East-West orientation. The proposed system involves photovoltaic panels and counter flow double pass (with fins). The photovoltaic solar thermal system is fixed on the roof of single span greenhouse. Experimental work was carried out during summer season. The results show the ventilation process changes the air inside temperature of the greenhouse to make it equal to the temperature required by the plants. The calculated root mean square error is 2.04 and correlation factor is 0.993 for the inside air temperature and 4.98, 0.98 respectively for the ground temperature.
