摘要

The aim of this study was to characterise the microclimate distribution in a greenhouse cooled by a mist system in comparison to the microclimate distribution of a roof ventilated greenhouse. For this purpose, air temperature, vapour pressure deficit and air velocity were measured in several positions inside an even-span greenhouse with a soilless rose crop, during periods with: (i) natural ventilation only, by means of a continuous roof vent and (ii) a mist-system operating associated with natural ventilation. The results indicated that fog induced a more homogeneous field for temperature and humidity, providing a more intensive mixing of the inside atmosphere, while natural ventilation induced high vertical temperature gradients.
