Computer simulation of multiroom temperature and humidity variation under variable infiltration conditions

Developed in this study is the computer simulation program which can predict the temperature and humidity variation in multiroom of a residence, especially under variable opening conditions such as doorway open or close according to inhabitants behaviors. In the multizone infiltration calculation, the special process is devised to make the computation stable, never failing to converge. In the humidity calculation, two parameters related to the absorption and desorption of the surface finishing of a wall are, also, presented. The validity of this model is examined and the application to a single family with four persons are demonstrated.
