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 ...
Convective and ventilation transfers in greenhouses, Part 1: the greenhouse considered as a perfectly stirred tank
(2002)
In this paper, the characterization and modelling of the most relevant convective transfers contributing to the elaboration of the greenhouse climate are reviewed. Convective transfers include heat and mass transfers between ...
Effect of vent arrangement on windward ventilation of a tunnel greenhouse
(2004)
The effect of ventilation configuration of a tunnel greenhouse with crop on airflow and temperature patterns was numerically investigated using a commercial computational fluid dynamics (CFD) code. The numerical model was ...
Influence of the heating method on greenhouse microclimate and energy consumption
(2005)
The influence of the heating system method on greenhouse microclimate was investigated overnight, using an experimental greenhouse tunnel with a tomato crop. The heating system consisted of plastic heating pipes located ...
Natural ventilation performance of six greenhouse and tunnel types
(1997)
The physical basis of natural ventilation is reviewed and the ventilation performance examined of six different greenhouse and tunnel types equipped with either roof or side, or both roof and side vents. Altogether, sixteen ...
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 ...
Convective and ventilation transfers in greenhouses, part 2: Determination of the distributed greenhouse climate
(2002)
In this paper, the characterisation and modelling of the most relevant convective transfers contributing to the description of the distributed greenhouse climate are studied in detail. After a brief review of the equations ...
Greenhouse microclimate and soilless pepper crop production and quality as affected by a fog evaporative cooling system
(2007)
The influence of greenhouse! humidity control on greenhouse microclimate, crop transpiration rate, and yield and. fruit quality of a soilless grown pepper crop was studied in a greenhouse located at the coastal area of ...
ASSESSMENT OF A TYPICAL GREEK SHEEP BARN BASED ON POTENTIAL HEAT-STRESS OF DAIRY EWES
(2014)
This article studied the potential seasonal heat-stress of dairy ewes housed in a typical naturally ventilated sheep barn located close to the east coast of central Greece. Heat stress was assessed using the Temperature ...
INFLUENCE OF HEATING SYSTEM ON GREENHOUSE MICROCLIMATE DISTRIBUTION
(2010)
Convective and radiative heat transfer from heating systems significantly determines greenhouse microclimate during the cold period of the year. These mechanisms are complicated because they combine free and forced convection ...
