Abstract:V diplomskem delu je analiziran prenosu toplote v rastlinjaku in izvedena primerjava različnih ogrevalnih sistemov. Preračun temelji na statistični analizi klimatskih razmer področja, kjer se rastlinjak nahaja. Glede na konstrukcijske tipe rastlinjaka z enojnim kaljenim steklom, dvojnim izolacijskim steklom in polikarbonatnimi ploščami je izračunan letnei primanjkljaj toplote. Toplotne izgube so razdeljene na: izgube zaradi prehoda toplote skozi material, izgube zaradi kondenzacije na površini stene in izgube zaradi ventilacije. Vmodelu je upoštevan toplotni dobiček s sončnim obsevanjem. Na podlagi dobljenih vrednosti letnega primanjkljaja toplote je narejena ekonomska analiza uporabe različnih načinov ogrevanja (kotel na lesne sekance in plinski kotel) in njihova kombinacija (kogeneracija). Izbiral se je optimalen sistem za boljši izkoristek prostora.

Title:ANALYSIS OF THE ENERGY NEEDS OF GREENHOUSES
Abstract:In the thesis is presented analysis of heat transfer in the greenhouse and implementation of economically efficient heating system with a statistical analysis of the climatic conditions of the area, where the greenhouse is located. Depending on the type of construction of the greenhouse with single tempered glass, double insulation glass and polycarbonate sheets we carried out the calculation of annual loss of heat. Heat losses were divided into three areas: losses due to heat transfer through the material, losses due to condensation on the surface of walls and losses in relation to ventilation. Heat from solar radiation was also considered. On the basis of the values of the annual heat deficit it was made an economic analysis of the use of the various possible ways of heating (woodchip boiler and gas boiler) and their combination (co-generation). Depending on the results it was choosen the optimal system for better use of space.
Keywords:greenhouse, heat loss, radiation, economic analysis, heating systems
