W projektowaniu przegród zewnętrznych budynków z uwagi na ich izolacyjność cieplną zachodzi konieczność wyznaczenia całkowitego oporu cieplnego i współczynnika przenikania ciepła. Składnikiem obydwu tych parametrów są opory przejmowania ciepła po wewnętrznej i zewnętrznej stronie przegród. Opory te wynikają z różnych wartości współczynników przejmowania ciepła. Wykonywanie obliczeń cieplno-wilgotnościowych...
This paper compares the predicted insulation of clothing (Iclp) in Toruń and Koniczynka, presented using a scale of evaluation of thermal environment proposed by B. Krawczyk (2000). The annual mean value of predicted insulation of clothing in urban areas of Toruń was equal to 1.0 clo, which was 0.1 less than in the agricultural area of Koniczynka. The influence of atmospheric circulation on the Iclp...
In the article the resulted results of researches of accumulation of moisture. Got model of accumulation of moisture: there is determination of temperatures on-the-spot and depth of soil, closeness, capillary potential of soil and absolute humidity of air, thickness of teployzolyacyynogo layer. The use of the offered technology will allow to optimize, to manage forming of harvest of agricultural cultures.
Insulation boards from thermoplastic bonded bark. Within this work, boards from thermoplastic bonded bark were made. Grinded bark of coniferous species and recycled polyethylene were used. Four variants of boards were manufactured: three of varying polyethylene weight ratio: 30, 40 and 50%, and fourth UF resin bonded. Assumed density of boards was 300 kg/m3, and thickness of 18 mm. Manufactured boards...
