| 摘 要： | 利用空气焓差法进行热泵空气侧换热量测量时，通常采用测流量法测量风的流量和截面平均温度。这种方法受温度测量布点的限制，使精度很难进一步提高，本文对这种方法进行了改进，采用风量测量和风速测量对温度进行加权的方法，并对这两种方法进行了比较、分析。

| Abstract: | When we measure the air heat capacity of heat pump by enthalpy potential method, the flow rate measuring method was used to measure flow rate and sectional mean temperature of air. This method is limited by temperature measuring stationing. Its precision is difficult to improve. In this paper, the method is improved, we use flow rate measuring method and air velocity weighting temperature method. Moreover, two methods were compared and analyzed. |
