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 analyzes the air infiltration process under the combined action of wind pressure and hot pressure, proposes a new calculation method and calculation formula of infiltration volume, and compiles a corresponding computer program, and explains its principle and use method. According to the current HVAC specifications (GBJ19-87), a meteorological parameter database was established and the meteorological parameters can be read directly during computer operation. Because this method considers the influence of the internal partition of the building on the amount of seepage, it is more reasonable and accurate than the previous method.
