Greenhouse microclimate and dehumidification effectiveness under different ventilator configurations
(2007)
In this paper, the efficiency of two different greenhouse ventilation opening configurations on greenhouse microclimate during dehumidification process with simultaneously heating and ventilation was analysed by means of ...
Study of a passive solar heating greenhouse crop grow gutter
(2011)
Water-filled transparent polyethylene tubes have been used as a passive solar system in greenhouses in Greece. In this work, the performance of a passive solar heating system used to serve as a crop grow gutter is studied. ...
Investigation of flow patterns in a greenhouse with mechanically assisted ventilation
(2011)
In the present work, the effect of fan ventilation in an arc type tunnel greenhouse under the encumbering action of solar radiation is studied. Results are accrued for the air velocity, temperature, pressure, vapour and ...
Flow characteristics and temperature patterns in a fan ventilated greenhouse
(2008)
The effects of solar radiation distribution during fan ventilation in an arc type tunnel greenhouse in various hours of daylight were numerically investigated. Inside the greenhouse there was a tomato crop 1.5 m tall. For ...
Efficiency of physical means of IPM on insect population control in greenhouse crops
(2011)
The efficiency of insect screens and photoselective covering materialson insect population control was experimentally evaluated. The experiments were performed from 2000 to 2004 in three greenhouse tomato, PE-covered ...
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 ...
Monitoring particulate matter levels and climate conditions in a Greek sheep and goat livestock building
(2011)
Atmospheric pollutants from livestock operations influence air quality inside livestock buildings and the air exhausted from them. The climate that prevails inside the building affects human and animal health and welfare, ...
Preliminary findings on seasonal heat stress of sheep
(2012)
This paper studies the heat stress conditions imposed onto sheep housed in a naturally ventilated sheep barn during the four seasons of a year. The barn is located near the east coast of central Greece. Heat stress is ...
Effects of anti-drip cover materials on microclimate and production of a hydroponic cucumber crop
(2008)
Recent year's concerns about food safety, environmental pollution, worker's safety, resistance to chemicals and the need for rational use of energy stimulated extensive research concerning the development of alternative ...
Numerical simulation of thermal behavior of a ventilated arc greenhouse during a solar day
(2010)
In the present study the transport phenomena occurring inside a ventilated arc type tunnel greenhouse are simulated during a solar day taking into account the optical properties of plants only in the photosynthetic active ...
