| Abstract |
This paper aims to evaluate performances of ventilation and insulation of 6types PVS(Passive ventilation skin) by numerical simulation. The results are as follows. 1) The result of Performance of ventilation by pressure difference, it was shown that the amount of ventilation changed bigger under 1Pa and amount of ventilation increased according to increase opening area (αA). Although same opening area of PVS, it can predict that pressure differences cause ventilation differences. 2) In case of same opening area of PVS, however, it was changed the amount of ventilation each types of PVS that is distinguished opening area by flow coefficient. 3) Dynamic U-value that represents performance of insulation PVS was similar change upper αA40 cm2/m2, great change in casse of 0.1 Pa pressure difference. In case of αA10 cm2/m2, it was changed bigger under 0.3 Pa pressure difference, αA20 cm2/m2 of PVS was changed under 0.2 Pa pressure difference. |
