Processes and devices for climatizing greenhouses |
摘要 |
The object of the invention consists of processes and devices which make it possible to vary the opacity of the covering of a greenhouse in order to maintain within the latter a luminosity which is substantially constant. A greenhouse according to the invention includes a transparent covering and transparent collectors, which are located parallel to the covering, which make up part of a closed circuit in which water containing in suspension a product P which partly absorbs the visible spectrum, and the infra-red, is caused to circulate and the concentration of product P in the suspension is varied in order to modulate the coefficient of absorption within the visible spectrum.
