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 ...
Improvement of greenhouse microclimate distribution by means of air mixing fans
(2012)
The objective of this work was to experimentally investigate the influence of air mixing fans on air temperature and humidity distribution in an arched roof greenhouse. The greenhouse was occupied by a tomato crop and ...
Microclimate of a pepper crop under screenhouse conditions
(2012)
In the present study, the influence of three different shading nets with different colour, shading intensity and porosity on the screenhouse and crop microclimate was experimentally investigated. The experiments were carried ...
QUANTIFICATION OF THE VENTILATION OF A GREENHOUSE WITH A ROOF OPENING
(1995)
Measurements of air exchange rates were performed in situ in a glasshouse equipped with a continuous roof opening. These measurements were carried out using the decay rate method with N2O as tracer gas. Simultaneously, ...
OVERALL HEAT-TRANSFER COEFFICIENT OF A GREENHOUSE COVER
(1994)
Theoretical considerations concerning the greenhouse energy behaviour during the night, allow us to propose an evaluation method of the overall heat transfer coefficient through the greenhouse cover material as a function ...
Numerical modelling and experimental measurements of pesticides dispersion in a naturally ventilated greenhouse
(2008)
In the present study a commercial CFD code was used in order to investigate the dispersion of a pesticide inside an arch type tunnel greenhouse with continuous side vents. The greenhouse was cultivated with a tomato crop ...
Fan and pad evaporative cooling system for greenhouses: Evaluation of a numerical and analytical model
(2008)
An experimental greenhouse equipped with fan and pad evaporative cooling is analysed using two different models. The first one consists of a numerical simulation approach applying a commercial CFD code. The main aspects ...
Differences in required structural efficiency of standard commercial steel greenhouses among EU countries: A hellenic experience
(2012)
Since the climate and seismic conditions vary significantly among European countries (and sometimes even in different areas of the same country) the European Standard for the design and construction of greenhouses for ...
Effect of Irrigation Scheduling on Gerbera Flower Yield and Quality
(2010)
Better understanding of the effects of irrigation frequency and dose on flower production of gerbera plants (Gerbera jamesonii) can lead to optimal water management and crop yield. Measurements of greenhouse microclimate ...
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 ...
