Solar collector constructed of welded plastic foils; Solfanger fremstillet af sammensvejset plastfolie

Technical Report:

Abstract

The aim was to construct a solar collector of welded plastic foils which, it was reckoned, would be cheaper to produce than those currently on the market. The solar collector consists of several layers of plastic foil welded together in a certain pattern. The layer which surrounds the water is made of black plastic which absorbs the solar light and the other layers are of clear plastic. The insulating layer can be blown up - which increases the insulating properties. Parts for in- and outlet of water and eyelets for fixing the solar collector can be added. Transport of this collector is very easy when the air is let out. It can be used on house roofs, in connection with swimming pools, camping areas and caravans etc., though in connection with larger areas of solar collectors its service life would be shorter and would have to be secured against extreme weather conditions. The design and choice of materials are further elaborated and the test results are given in detail. It is concluded that non-insulated solar collectors are only suitable to raise the temperature 5-6 degrees centigrade above the surrounding temperature. The water runs evenly through all the channels in the  More>>

It is concluded that non-insulated solar collectors are only suitable to raise the temperature 5-6 degrees centigrade above the surrounding temperature. The water runs evenly through all the channels in the solar collector with parallel channels. The welding of the plastic materials must not present large piezometric surfaces as these can easily be torn. Such areas should be reinforced to achieve resistance to pressure in vulnerable places.
