1 Thermal Modeling of a Greenhouse Fish Pond System

A thermal model has been developed for heating the aquaculture pond by even span greenhouse. Numerical computations have been performed for a typical day in the month of January, 2005 for the composite climate of New Delhi. The energy balance equations have been written considering the effects of conduction, convection, radiation, evaporation and ventilation, etc. The model has been validated with the experimental data. From the results, it was observed that the predicted values of room temperature and water temperature in the tanks of the greenhouse obtained from the proposed model exhibited fair agreement with the experimental values
