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 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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
