Computation of Thermal Environment of Lightweighted Steel Temporary House in Natural Ventilation
After the earthquake happened in WenChuan of China on May 12th, 2008, lightweighted steel temporary house has been widely used as temporary settlement for peoples survived in the disaster. In order to investigate the thermal environment performance of the lightweighted steel temporary house, the temperature variations of its envelope and indoor air were studied. A geometric model based on one standard lightweight steel temporary house was established; and the one-dimensional unsteady heat transfer equation was established to measure the thermal conduction of the buildings envelope. Also the thermal balance equation was combined with the natural ventilation to simulate variation of the indoor air temperature and the natural ventilation of the building. The meteorological data of one summer day in south China was used to compute the temperature variation of buildings envelope and indoor air. The following conclusions are derived: The lightweighted steel EPS board has a satisfied heat-insulating performance. However, roofs temperature becomes relatively high when the sun radiation becomes strong. Hence, the roofs heat insulation should be further improved. In natural ventilation, variation of the outdoor air temperature influences the indoor’s air temperature greatly.
