Cím:	Energy and comfort aspects of infiltration at closing elements of buildings / F. Kalmár, T. Kalmár, E. Varga, I. Kocsis, T. Jenei, Gy. Csomós
Dátum:	2008
Megjegyzések:	Nowadays, due to the energy saving purposes in the building sector, at new buildings and at refurbishments, modern closing elements are built-in, with very good thermal insulation and air tightness properties. The frame of these elements may be from wood, plastic or metal. Each of them has advantages and disadvantages, but during the exploitation the initial value of air tightness may become higher. This phenomenon may appear because of the initial tensions in the materials or due to the failures in the built-in procedure. The infiltrated air-flow through the frame gaps may be significant. Of course there are lots of factors which have an influence on the infiltration beside the gaps surface such as wind pressure, extractor fans etc. Having infiltration the energy properties of the building are changed considerably and, depending on the rooms position in dwelling, comfort problems may appear. In this paper the infiltration is analysed from energy and thermal comfort point of view. Calculus has shown that having lower air tightness the energy consumption for heating up the infiltrated fresh air flow can be 3-5 times higher than the design value. If the infiltrated air is not heated up to the internal set point value the internal temperature can decreased significantly.
