Résumé

This study investigated the thermal behaviour of an occupied room exposed to winter weather conditions by means of quasi-steady-state model of the room. The space is not air-conditioned during the winter season, i.e. there is no humidity control and thermal performance of heaters maintains desired indoor air temperature. The model was set up and a series of tests was carried out in order to validate the mathematical model and determine the thermal characteristics of the enclosure. The model features a water equivalent content of the room, time-varying heat transfer coefficients, and boundary conditions onto surrounding walls, respectively. As a full dynamic method it accounts for the thermal influence of outdoor climate conditions, occupancy use and other internal sources of thermal energy. The article emphasizes the selection of system boundaries and practical calculations of radiation heat exchange without claiming shape factor algebra. The numerical results of temperature transient time responses obtained from mathematical model are well in accordance with those obtained from measurement in the actual room.
