Environmental impact of greenhouse tomato production in France
The environmental impact of greenhouse production in France is poorly documented. Environmental benefits versus drawbacks of greenhouse production are not well known. Assessments that intregrate
Modelling of Air Exchange Rate in a Greenhouse Equipped with Continuous Roof Vents
Abstract Several models of air exchange in a greenhouse are derived considering the two main driving forces of natural ventilation (stack effect and wind effect) and compared with experimental
Analysis of Greenhouse Ventilation Efficiency based on Computational Fluid Dynamics
The effect of wind speed and roof vent opening configuration on airflow and temperature patterns in a compartmentalised glasshouse was numerically analysed by means of two-dimensional computational
PA—Precision Agriculture: Convective and Ventilation Transfers in Greenhouses, Part 1: the Greenhouse considered as a Perfectly Stirred Tank
In thispaper, the characterization and modelling of the most relevant convective transferscontributing to the elaboration of the greenhouse climate are reviewed. Convective transfers include heat and
NATURAL VENTILATION OF A GREENHOUSE WITH RIDGE AND SIDE OPENINGS: SENSITIVITY TO TEMPERATURE AND WIND EFFECTS
An air exchange rate model of a Mediterranean greenhouse with ridge and side openings combining temperature and wind effects as driving forces of the natural ventilation was developed and tested on
Review: Effect of ventilator configuration on the distributed climate of greenhouses: A review of experimental and CFD studies
Ventilation processes inside the greenhouse strongly affect air renewal and internal climatic conditions, which themselves interact with the growth and homogeneity of the crop. Natural ventilation is
Effect of Vent Openings and Insect Screens on Greenhouse Ventilation
The objective of this work was to experimentally investigate the influence of vent type (side, roof or both) and of an anti-aphid insect screen used to prevent insect intrusion on the ventilation
The mechanisms involved in the natural ventilation of greenhouses
Abstract Although natural ventilation is one of the major mechanisms that controls the greenhouse climate, our understanding of the underlying processes remains insufficient to allow accurate
Greenhouse crop transpiration simulation from external climate conditions
A new and simple greenhouse crop transpiration model enabling predictions from outdoor conditions is presented and the parameters involved are discussed with respect to different types of
A simple greenhouse climate control model incorporating effects of ventilation and evaporative cooling
Abstract A greenhouse climate model, incorporating the effects of natural ventilation and evaporative cooling (fog-system), is proposed and discussed. Linearization of the greenhouse heat and water
