摘要
通过对空调房间的空调装置启动过程中,房间的传热与流动的非稳态过程用计算流体力学(CFD)软件Flu-ent进行模拟,得到房间对不同扰量的飞升曲线建立了空调房间开机过程动态响应特性的数学模型,并分析了房间的动态响应特性。通过自行搭建的住宅用水源热泵系统性能试验台,对不同室外温度下的启动过程进行实验研究,对建立的数学模型进行了验证。这一数学模型对空调末端的控制具有一定的实际意义。
In this study, Fluent as a computational fluid dynamic software was used to simulate the process ot unsteady heat conduction and convection of the air in an air- conditioning room during the start- up process of the air- conditioning instruments. On the basis of the flying- rising curves obtained from the process of the simulation, a mathematics model established to reflect the dynamic response of the air in the air- conditioning room during the air- conditioning instruments starting up was analyzed and testified through start- up experiments under various out- door temperature.
