Price Industries Limited, a Manitoba-based leader in North America of the design and manufacture of heating**ventilating, and air-conditioning (HVAC) equipment, needs to improve the performance of a compact air**supply fan unit. The unit is commonly used to provide airflow to building zones where the heating and cooling**loads vary.**The unit consists of a casing, an electronics panel, a small centrifugal fan, the fan housing, and a motor. The**improvement of the performance of the fan unit will lead to significant long-term energy savings for customers.**It is not obvious which changes to design parameters are required to achieve the improved performance. It may**require a combination of changes to the casing, fan housing, and fan blades. Exploring these changes**experimentally could involve many costly and time-consuming trial-and-error tests.**The company wants to be able to use CFD (Computational Fluid Dynamics) modelling to explore design**changes that will result in optimization of the fan unit. The CFD analysis will predict the three-dimensional air**flow in the unit. Later, for the optimization process, the geometry and fan parameters can be changed and the**resulting performance will be predicted in detail by the software. This capability will yield economic benefits**for Price Industries by shortening the design cycle and making the company more competitive in this product**category. The first step, however, is to obtain a reliable CFD model for the current fan unit configuration.**The objectives of this project are to develop a steady-state CFD model of the fan unit using commercial**software and to validate that model. Model parameters will be varied and comparisons with available in-house**experimental data will be performed.

总部位于马尼托巴省的普莱斯工业有限公司是北美采暖、通风和空调(HVAC)设备设计和制造的领先者，该公司需要改进紧凑型送风**风机机组的性能。该装置通常用于为建筑区域提供气流，这些区域的供热和制冷负荷**各不相同。**该装置由外壳、电子面板、小型离心式风扇、风扇外壳和电机组成。风扇机组性能的**改进将为客户带来显著的长期节能。**需要对设计参数进行哪些更改才能实现性能的改善并不明显。这可能**需要更换机壳、风扇外壳和风扇叶片。在实验中探索这些变化**可能涉及许多昂贵且耗时的反复试验。**该公司希望能够使用CFD(计算流体动力学)建模来探索设计**将导致风扇单元优化的变化。CFD分析将预测机组内的三维空气流动。随后，在优化过程中，可以改变几何参数和风扇参数，并通过软件对**产生的性能进行详细预测。这一能力将通过缩短设计周期并使公司在该产品**类别中更具竞争力，为普莱斯工业公司**带来经济效益。然而，第一步是获得当前风机机组配置的可靠的CFD模型。**本项目的目标是使用商业软件开发风机机组的稳态CFD模型**并验证该模型。模型参数将变化，并将与现有的内部**实验数据进行比较。
