本研究开发了一种基于转速和风机叶轮尺寸估算家用燃气炉中由电子换向电机（ECM）驱动的鼓风机能量性能的方法。作为第一步，在0.1到1.2英寸的外部静压（ESP）范围内测量了三家制造商的五种不同ECM鼓风机的气流、功率和转速。w、 g.（25至300 Pa）在仪器良好的实验室环境中，带有校准的喷嘴气流室。 然后根据发动机控制模块（ECM）的功率和鼓风机的效率测量值确定气流的功率比。通过对转速和鼓风机效率之间关系的研究，得出了效率与鼓风机雷诺数之间的相关性，该雷诺数取决于转速和鼓风机叶轮尺寸。结果表明，通过使用发展的指数相关性，可以准确预测ECM鼓风机的效率，R2值范围为0。 975比0.981。此外，预测和实验测定效率之间的比较表明，92%的预测数据点在实验测定结果的+/-10%范围内。本研究的结果提供了一种基于转速和风机叶轮尺寸知识，根据ECM鼓风机效率预测能量性能的方法。此外，本研究中产生的实验数据和相关性可用于模拟ECM鼓风机在一定转速范围内的效能行为。 引用:2016年年度会议，密苏里州圣路易斯，会议论文

This study developed a method to estimate the energy performance of blowers that are driven by electronically commutated motors (ECMs) in residential gas furnaces based on rotational speeds and blower wheel dimensions. As the first step, the airflow, power, and rotational speed of five different ECM blowers from three manufacturers were measured over a range of external static pressures (ESPs) from 0.1 to 1.2 in. w.g. (25 to 300 Pa) in a well-instrumented laboratory environment with a calibrated nozzle airflow chamber. Then, the energy performance of each ECM blower was determined from the airflow and power measurements and characterized in terms of efficacy, which is the ratio of blower power to airflow rate. The investigation of the relationship between rotational speed and blower efficacy led to the correlation of efficacy with the blower Reynolds number that is dependent on rotational speed and blower wheel dimensions.Results show that the efficacy of ECM blowers can be accurately predicted by using the developed exponential correlations as evidenced by the high R2 values ranging from 0.975 to 0.981. Furthermore, a comparison between the predicted and experimentally determined efficacies shows that 92% of the predicted data points are within +/-10% of the experimentally determined results.Results generated from this study provide a method to predict the energy performance in terms of efficacies for ECM blowers based on the knowledge of rotational speed and blower wheel dimension. In addition, the experimental data and correlations produced in this study can be used to model the ECM blower efficacy behaviors over a range of rotational speed.
