ISHS Acta Horticulturae 115: Symposium on More Profitable Use of Energy in Protected Cultivation

RADIATION PROPERTIES OF THERMAL SCREENS

Author:   H. Tantau
DOI:   10.17660/ActaHortic.1981.115.75
Abstract:
By measuring the radiation properties of materials for thermal screens it is possible to estimate the energy saving of a screen system. Measurement equipments have been developed for measuring the transmissivity and emissivity of screen materials. Besides this the efficiency of screen materials due to energy saving has been measured in a small model.

An empirical relation has been developed for the influence of radiation properties of the screen materials on energy saving. By means of this evaluation it is possible to predict the energy saving of new screen materials by measuring the radiation properties of the material.
