THE IMPACT OF INSECT SCREENS AND VENTILATION OPENINGS ON THE GREENHOUSE MICROCLIMATE
(2008)
The objective of this work was to experimentally investigate the influence of vent type (side, roof, or both) and of anti-aphid insect screens on airflow, air temperature, and air vapor pressure deficit distribution in a ...
Effect of vent opening and insect screens on greenhouse microclimate distribution
(2006)
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 on airflow and temperature distribution of a mono span greenhouse round arch ...
The effect of vent configuration and insect screens on greenhouse microclimate
(2005)
The influence of insect screens and vent configurations on airflow and temperature patterns in an arched plastic covered greenhouse used for cultivating tomatoes was analysed using a commercial computational fluid dynamics ...
Pressure field and airflow at the opening of a naturally ventilated greenhouse
(1998)
Direct estimation of airflow at the vent opening by means of differential pressure measurements were performed in a twin-span greenhouse equipped with a continuous vent at the gutter. Application of Bernoulli's equation ...
Air flow, temperature and humidity patterns in a greenhouse tunnel
(1999)
Air distribution and climatic heterogeneity in greenhouses interfere with plants activity and influence largely crop activity and more particularly transpiration and photosynthesis. This is particularly true for the tunnel, ...
Air flow and associated sensible heat exchanges in a naturally ventilated greenhouse
(1997)
In order to investigate the three-dimensional nature of the air flow within the greenhouse, a three-dimensional sonic anemometer was used for the direct measurement of air and heat exchange inside the greenhouse and through ...
Effect of Vent Openings and Insect Screens on Greenhouse Ventilation
(2006)
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 rate of a round arch with ...
Influence of an insect screen on greenhouse ventilation
(2002)
The influence of an insect screen on ventilation rate was experimentally investigated in a multispan glass-covered greenhouse equipped with a continuous roof vent, located at the University of Thessaly near volos in the ...
Wind induced air exchange rates in a greenhouse tunnel with continuous side openings
(1996)
To study the influence of wind speed on ventilation rates, experimental trials were carried out in a plastic tunnel with continuous side ventilators. This type of greenhouse is the most representative of Mediterranean and ...
