摘要
本文通过对风压和热压共同作用下空气渗透过程的分析,提出了新的渗风量计算方法和计算公式,编制了相应的计算机程序,并说明了其原理和使用方法。文内依据现行暖通规范(GBJ19-87),建立了气象参数数据库,计算机运行中可直接读取气象参数。由于本方法考虑了建筑内部隔断对渗风量的影响,因而与以往的方法相比,计算结果更合理、更准确。
This paper analyses the course of air infiltration caused by joint wind and ehimney action, puts forward a new calculating method and calculating formulas, draws up a corresponding computer program and illustrates its principle and utilizing method.@ Meanwhile, a meteorological parameter data file is set up according to current HVAC standard (GBJ19-87), which can be gained directly in computer program operation. Because the internal partition of the structure has been drawn into calculation, the air infiltration can be calculated accuratey.
