SIGNIFICANT PARAMETERS FOR CHARACTERIZATION OF THE VENTILATION AND COOLING OF GLASSHOUSES |
| Author: | B.v. Elsner |
| Abstract:
The glasshouse can be described as a wet heatexchanger, into which energy is introduced as solar radiation. Neglecting the amount of energy stored in the plants, soil, benches all energy must be taken away by a flow of a cooling medium or by passing through the boundary in form of conduction through the glass or convection through untightness. The boundary conditions of this system are the solar radiation QSa (W/m2), the ambient temperature ta (°C) and the ambient absolute humidity xa (gH20/kgair), | |
