VERFAHREN UND VORRICHTUNG ZUR VERMINDERUNG DER HEIZBELASTUNG EINES GEWÄCHSHAUSES

摘要

The heat load on a greenhouse (20) containing growing plants (27) is reduced by reducing the transpiration of the plants by reducing the rate of convective heat flow of air across the canopy of the plants. This is achieved by heating and dehumidifying the air in the greenhouse during periods of low light levels, such as at night, so that the need for ventilation is minimized.
