DETERMINATION OF AIR EXCHANGE FIGURES WITH REGARD TO CLOSED GREENHOUSES |
| Author: | H.-Chr. Gudehus |
| Abstract:
This is done by means of a fan pressing air into the interior of a not air-tight greenhouse. The amount of exchanged air is measured by equipping the fan with a wind tunnel; it is depending on the difference of pressure between the inside and outside of the greenhouse. The difference of pressure and the air exchange figures are applied to the natural conditions in the case of different air velocities. | |
