Optimum utilization of solar energy in greenhouses
- United Arab Emirates Univ., Al-Ain (United Arab Emirates). Dept. of Mechanical Engineering
The present study addresses the problem of poor climate control of the greenhouse environment in tropical regions and suggests possible on-line environmental control procedures and systems. The weather parameters as well as the greenhouse parameters influencing indoor climatic conditions are experimentally investigated and theoretically modeled in the United Arab Emirates (Latitude 24{degree}N). A model is formulated for the greenhouse energy balance including solar radiation, long wave thermal radiation, soil and plant evapotranspiration, thermal convection and heat storage. Experimental measurements and theoretical predictions of incident and transmitted solar radiation show excellent agreement. The energy balance model is applied on typical greenhouses under the local climatic conditions of the U.A.E to predict the inside temperature and relative humidity. The model includes the effect of rates of ventilation and evaporative cooling spray water.
