$a Modelling of the energy consumption on the unilateral convective heating process of furniture elements before their lacquer coating $f Nenčo S. Delijski ... [et al.] 215 $c Grafy, obr. 320 $a Lit. 330 $a Two mutually connected 1D linear mathematical models created and solved by the authors earlier, are updated and presented as a nonlinear model . The first of them allows the computation of the non - stationary temperature distribution along the thickness of subjected to unilateral convective heating flat wooden furniture elements before their subsequent lacquer coating. The second one allows the computation of the non - stationary distribution of the temperature along the thickness of the carrying rubber band, on wh ich the non - heated surface of the furniture elements lies. A methodology for the computation of the specific (for 1 m2 ) energy consumptions needed for warming up both the furniture elements and the carrying rubber band, and also for covering of the heat em ission from the band to the surrounding air are suggested. The methodology is based on the integration of solutions of two mutually connected nonlinear models mentioned above. For the numerical solution of the models with the aim at applying the methodology , a software program as an input in the calculation environment of Visual Fortran Professional was prepared . The computations were carried out to determine the specific energy consumption during the unilateral heating process of flat oak furniture elements with an initial temperature of 20° C, moisture content of 8 %, thickness of 16 mm, width of 0.6 m, and length of 0.6 m, 1.2 m, and 1.8 m, during their 10 min convective heating by hot air with the temperature of 100 o C and velocity of 5 m·s - 1 . At the temperature of the surrounding air of 20° C , and the initial temperature of 20° C , the thickness of the rubber band was 4 mm, the width was 0.8 m, The obtained results can be used for technological and energy calculations of unilateral heating processes of furniture elements at different boundary conditions, as well as in the software of systems for model based automatic control of these processes aimed at improvement of thermal conditions for the subsequent lacquering of the elements. 463 -1
