Abstract

A new Finite element model for HVAC applications is introduced. The model incorporates flow turbulence, buoyancy effects and unsteadiness. Also, the model accommodates complicated boundaries due to complex geometries and perforated tiles. Experimental validation is provided and extensive results for flow and temperature contours are presented. Temporal and spatial resolution prove that the model can capture important HVAC features as thermal comfort, buoyancy induced flow, complex boundaries.

复杂暖通空调应用的高效有限元建模
介绍了一种新的暖通空调应用有限元模型。该模型考虑了湍流、浮力和非定常效应。此外,由于复杂的几何形状和穿孔瓷砖,该模型容纳了复杂的边界。提供了实验验证,并给出了流动和温度轮廓的广泛结果。时间和空间分辨率证明该模型能够捕捉到暖通空调的重要特征,如热舒适、浮力诱导流动、复杂边界等。
