摘要
This paper proposed HVAC engineer should simulate natural ventilation (V-1) of building based on the Ventilation Network Model (VNM) and software of 'loop pipe network hydraulic calculation and analysis of hydraulic conditions (LPNHHC) V1.0' which is developed by Chongqing University. It presents two indexes, which are requirement of 'ventilation in local building regulation (V-2), and 'thermal comfortable ventilation (V-3)', should be used to evaluate the design talent on building natural ventilation. We can say the building ventilation design meet the requirement under the premise of V-1 bigger than V-2 and V-3 simultaneously. Architecture, otherwise, needs to modify the building design according to the comments of HVAC engineer. HVAC engineer should design mechanical ventilation (MV) if natural ventilation really can not meet the requirement after modification. It, at last, shows a case study of office building in Chongqing in order to prove the method proposed in the paper. We conclude that ventilation network model can be used to evaluate the design effect of building natural ventilation.
