Abstract

In this paper, we study a new way to prevent indoor ground condensation by controlling natural ventilation between outdoor and indoor, it adjust to reduce the indoor dew point temperature lower than the ground surface temperature as much as possible, so to prevent condensation. Through make a typical rural house model used for ICC software DesignBuilder, we have a simulation of controlling natural ventilation by changing ventilation opening area, thereby controlling indoor ground condensation hours. Studies have shown that: between March to July, simulate house model in the natural ventilation passive state with 100% full opening of the wall, there is a total maximum number of condensation hours of a rural house model; by changing percentage of ventilation opening area, it can significantly control the condensation hour number; it is not entirely a monotonic relationship between the changing of the number of condensation hours and the changing of ventilation opening area; in simulation, when increasing percentage of ventilation opening area from 30% to 100%, the number of condensation hours has a condensation fluctuations, not simply a monotonically increasing.
