方形散流器送风参数对气流分布影响实验研究

本文目的是研究方形散流器的送风参数对室内气流分布的影响规律。在模拟建筑内区的空调实验室进行了实验，测出了不同送风参数下室内所有测点的温度和速度。对实验数据分析得出空气分布特性指标、温度不均匀系数以及速度不均匀系数与送风速度的关系曲线，并用TECPLOT软件实现了温度场、速度场的可视化。结果表明在室内热源和控制温度不变时，随着送风速度的增大，送风温度升高，送风温差减小，室内工作区的空气分布特性指标增大。

Study on the Impact of Supply Air Parameters of Square Diffusers on Air Distribution

The objective is studying how supply air parameters of square diffuser affect room air distribution. Tests were conducted in an air conditioning laboratory, which simulated a typical interior room of office building. Temperatures and velocities of all measurement locations through the space under different supply air parameters were measured. The relationship curves of air diffusion performance index, nonuniformity coefficient of temperature and nonuniformity coefficient of velocity were respectively obtained through test data analysis. Temperature fields and velocity fields were visualized by TECPLOT software. The results were shown that as room heat source and control temperature keep constant, with the increase of outlet velocity, supply air temperature will rise, supply air temperature difference will decrease and air diffusion performance index in the occupied zone of the test room will increase.
