|Abstract:||The total energy consumption of Chinese buildings has been rising year by year, and the energy consumption of the ventilation and air-conditioning system accounts for more than 20%. While maintaining a good indoor comfort, it is very important to improve the design of the ventilation and air-conditioning system to achieve energy saving and emission reduction. However, the current industry specifications are rarely related to vent design such as the length-to-width ratio. The focus of this study is the influence of the length-to-width ratio of the vent inlet of the ventilation and air-conditioning system on the indoor air distribution. We took the Shanghai area as an example, established a 1:1 real office model, and used numerical simulation methods to explore. Through the analysis of the indoor flow velocity diagram and temperature field diagram obtained by simulation, the result shows that when the length-to-width ratio of the vent inlet is 1, the indoor air distribution is better, which can bring a more comfortable experience to the indoor personnel.|
