DETERMINATION OF THERMAL TRANSPARENCY OF PLASTICS MATERIAL FOR COVERING GREENHOUSES

Acta Horticulturae, 1990
La consommation thermique d'une serre pour son chauffage dépend essentiellement de sa couverture et de son comportement sous un climat extérieur donné. De nombreux films plastiques aux propriétés mal connues sont apparus sur le marché. Il devient alors nécessaire de caractériser les matériaux de couverture par un coefficient de déperdition, de déceler ...

SOIL SOLARIZATION IN GREENHOUSE BY USING ECO-COMPATIBLE PLASTIC FILMS

Acta Horticulturae, 2006
Amongst the different eco-compatible techniques, the soil solarization using plastic films, in temperate regions and in greenhouses, represents one of the better alternatives to the use of methyl bromide in order to contain soil borne diseases. On the other hand, it must be noted that a high employment of plastic materials in agriculture causes the ...

A water-curtain heating system for plastic greenhouses

Journal of Agricultural Engineering Research, 1992
A possible alternative method of using power station waste heat has been investigated using a small-scale physical model and its performance compared with that predicted from thermodynamic principles. It employs a variation of the water-curtain surface-heating method first investigated experimentally by Canham in 1957.

Channelled plastic for greenhouse and skylight use

Solar Energy, 1981
Abstract Transparent, channelled, plastic sheets lend themselves to solar energy applications in which an interior space needs light but limited amounts of heat. We discuss the transmission of solar energy through such sheets with and without circulating water or water with dissolved ions.

The plastic greenhouse industry of Spain

El artículo analiza la industria de invernaderos de plástico en España, destacando su expansión en las últimas décadas gracias a factores como la crisis energética de los 70 y el bajo coste de los materiales. Se describe la predominancia de invernaderos de tipo "parral" en el sureste español, las prácticas agrícolas empleadas (riego, cultivos sin suelo,
