Thermal Modelling for Greenhouse Heating by Using Packed Bed

Nisha Kumari, G.N. Tiwari and M.S. Sodha
This study presents thermal modelling of rock bed with water for heating agricultural greenhouse. Numerical computations have been carried out for an east-west oriented even span greenhouse for New Delhi (28.5° latitude), India. Effect of void bed fraction, area of collectors on plant, room air, water and rock bed temperatures have been studied in detail. On the basis of numerical results, it is inferred that the plant, room air and water temperatures of the greenhouse increases significantly with the increase of collector area and decreases with the increase of void bed fraction, while rock bed temperature increases with the increase of void bed fraction.
