住宅热压引射自然通风技术的应用研究

Applied Research on Thermal Pressure Jet-induced Natural Ventilation Technology of Residence

为了深入研究和应用自然通风技术中的热压通风模式,文章对常规热压作用下的自然通风技术原理做了详细的论述,指出常规热压作用自然通风模式对单层建筑比较有效,同时分析了多层建筑利用该通风模式存在的问题。在此基础上,对多层住宅建筑提出了一种全新的热压引射自然通风模式,初步探讨了该通风模式的原理、特点,并建立了相应的模型,确定了该模式下的通风量要求、中和面的位置和各层通风动力大小。最后针对住宅中某典型户型做了初步的模拟分析,计算所得出的结果证实了热压引射自然通风模式在理论上是可行的,也为今后更进一步的研究热压作用自然通风新技术提供了一定的思路。

In order to further the research and application of the thermal pressure mode in the natural ventilation technology,the article thoroughly describes the principle of natural ventilation under conventional thermal pressure effect,pointing out the advantages of conventional thermal pressure natural ventilation mode in the single-buildings,while analyzing the problems of using this ventilation mode in the multi-storey buildings.On this basis,a new thermal pressure Jet-induced natural ventilation mode is proposed,then the principle and characteristics of this ventilation mode are discussed initially,and the corresponding model is established,the ventilation requirements,the 0-pressure surface location and the size of all levels of ventilation power are determined.In the end,the preliminary simulation analysis for a typical dwelling of residential units is done,the calculation results confirm that the thermal pressure Jet-induced natural ventilation technology is feasible in theory,and also provide some ideas for the further study of the new technology of thermal pressure natural ventilation..
