Application of the Gebhart-Block Model for Predicting Vertical Temperature Distribution in a Large Space Building with Natural Ventilation
MetadataShow full item record
Based on the Block model for predicting vertical temperature distribution in a large space, this paper describes an improved Gebhart-Block model for predicting vertical temperature distribution of a large space with natural ventilation. In this model, the Gebhart method for calculating interior surface temperature distribution is incorporated into the Block model for predicting vertical temperature distribution. The Gebhart method is put forward for calculating the surface temperature using the Gebhart absorption coefficient of each surface and a heat balance equation for coupled thermal conduction, convection and radiation of the enclosure. In the Gebhart-Block model, the influence of inside heat sources is also calculated. Its convective and radiative terms here are treated separately in the Block model and Gebhart method. The calculated results are compared with the measured data.
