现有的风机性能模型大多基于风机静压和风机风量。然而，对于典型的成套HVAC装置，由于内部部件的紧凑布置，会产生不理想的气流模式，从而导致现场风机静压波动和压力传感器安装困难。本文描述了风扇性能灰色箱模型的发展，该模型将风扇功耗与风扇速度和气流联系起来，两者都更容易测量。提出了几种实用的风机转速现场测量或预测方法，用于模型的实现和验证。 最后，使用制造商的数据对模型进行插值和外推评估，并用实验室数据进行验证。该模型可用于预测电耗和风机静压，进行风机类型、轮径宽度和空气密度的对比分析，以及风机运行的故障检测和诊断。单位:双引文:ASHRAE交易，第116卷，第。2010年奥兰多

Existing methods for fan performance model are mostly based on fan static pressure and fan airflow. However, for typical packaged HVAC units, a non-ideal airflow pattern arises due to the compact arrangement of the interior components, resulting in both the fluctuation of the field fan static pressure and the difficulties of installing the pressure sensors. This paper describes the development of the fan performance greybox model, which relates fan power consumption to fan speed and airflow, both of which are much easier to measure. Several practical field measuring or prediction methods of blower speed for the model implement and validation are proposed. Finally, the model is evaluated in terms of interpolation and extrapolation using the manufacturers’ data and validated with laboratory data. This model can be used to predict the power consumption and fan static pressure, for comparative analysis of fan types, wheel diameters widths and air density, and for fault detection and diagnosing of fan operation.Units: Dual
