加热和冷却设备中的气流速度对系统的性能有重大影响。流经空调和热泵盘管的流量不当会降低盘管的容量，流经炉膛热交换器的流量过低会导致系统在高温限位开关上循环，并且流速对管道系统的效率有重大影响。测量通过空气处理器的气流的主要方法是利用空气处理器的回流侧和供给侧之间的温度变化。然而，这种方法有很多缺点。最近，一种新的装置被开发出来，它提供了一种通过住宅空气处理器测量流量的简单方法。本文介绍了一项现场研究的结果，与温度变化法相比，评估了该装置的性能。 还讨论了该装置的潜在商业应用。单位:I-PCITION:研讨会，ASHRAE交易，第109卷，pt。堪萨斯城，2003年

The airflow rate in heating and cooling equipment has major implications for the performance of the system. Improper flow across air conditioner and heat pump coils degrades the capacity of the coil, low flow across the heat exchanger in furnaces can cause the system to cycle on the high-temperature limit switch, and the flow rate has major implications for the efficiency of the duct system. The primary method for measuring the airflow through an air handler uses the change in temperature between the return and supply side of the air handler. However, this method is known to have major drawbacks. Recently, a new device has been developed that provides an easy way to measure the flow rate through residential air handlers. This paper presents the results of a field study to evaluate the performance of this device compared to the temperature change method. Potential commercial applications of the device are also discussed.Units: I-P
