Numerical research on natural ventilation properties affected by opening doors and windows of residential buildings

In an environment without heating and cooling, studies the flow coefficients under the different opening combinations of the common side hung doors and sliding windows using Airpak software. Analyses the flow coefficients of multiple opening models in the wind pressed ventilation quantitatively. Builds a simulation platform, simulates and calculates the ventilation rate of a real room using multi-zone network model, and finds that changing the opening degree of doors and windows can change the effective ventilation area and affect the natural ventilation rate. Simulates and analyses the impact of the different opening combinations of doors and windows on air conditioning energy consumption by DeST-h software.
