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