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 ...
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 ...
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 ...
Effects of a UV-absorbing greenhouse covering film on tomato yield and quality
(2012)
The effect of blocking the ultraviolet (UV) solar radiation using a UV-absorbing low density polyethylene (PE) film on tomato crop yield and fruit quality was evaluated in a two-year study in two arched roof greenhouses ...
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 ...
Evaluation of thermal perception in schoolyards under Mediterranean climate conditions
(2015)
The aim of this paper was to study qualitatively and quantitatively the thermal perception and corresponding heat stress conditions that prevail in two schoolyards in a coastal city in central Greece. For this purpose, ...
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 ...
Experimental and modelling analysis of pesticide fate from greenhouses: The case of pyrimethanil on a tomato crop
(2012)
The distribution of a pesticide on target and non-target elements of a greenhouse, and its fate after application, was studied. The experiments were performed in a round arched greenhouse with vertical side walls containing ...
