A REFLECTING DEVICE FOR INCREASING THE EFFICIENCY OF USE OF SOLAR ENERGY IN DRYING PLANTS

摘要

Drying plants for drying agricultural products employ during drying large quantities of thermal energy. This energy is obtained, in most cases, by burning fossile fuels. It is possible to accomplish considerable savings of fuel with appropriate roof construction of drying plant (1) which provides the use of insolation which falls onto the roof. It consists from the dual roof plate with channels through which, by natural or forced convexion, air flows which is used for drying. the upper side of the plate absorbs solar energy and transfers the air. The invention being the subject of the patent protection consists the additional construction which increases the intensity of insolation by means of the principle of reflection. This is achieved so as that additional construction is formed of plate (4), dimensions similar to roof, high-brightness of surface, set along the edge of the roof, opposite to sun rays, under the angle that reflected raying as a whole or partially falls on the roof. Different possibilities are described for accomplishment of this additional construction.;Suare za suenje poljoprivrednih proizvoda troe u procesu suenja velike koliine toplotne energije. Ova energija dobija se, u najveem broju sluajeva, sagorevanjem fosilnih goriva. Mogue je ostvariti znatne utede goriva ako se naini takva konstrukcija krova suare (1) koja omoguuje da se koristi sunevo zraenje koje pada na krov. Ona se sastoji od dvostruke krovne ploe sa kanalima kroz koje, prirodnom ili forsiranom konvekcijom, struji vazduh koji se koristi za suenje. Gornja strana ploe apsorbuje sunevu energiju i prenosi je na vazduh. Pronalazak koji je predmet ove patentne zatite sastoji se u dopunskoj konstrukciji koja pojaava intenzitet sunevog zraenja korienjem principa refleksije. Ovo se postie na taj nain da dopunsku konstrukciju predstavlja ploa (4), dimenzija slinih krovu, visoko-sjajne povrine, postavljene na ivicu krova, naspramnu sunevim zracima, pod takvim uglom da reflektovano zraenje u celini ili delom pada na krov. Opisane su razliite mogunosti ostvarenja ove dopunske konstrukcije.[Drying plants for drying agricultural products employ during drying large quantities of thermal energy.
