The rateofheatflow between any two points increases with difference of temperature.
任何两点间的热流动速率则随温差的加大而增加。

When we measure the heat capacity ofheat pump by enthalpy measuring method, we use flowrate measuring method to measure flow rate and sectional mean temperature of air.
利用空气焓值测量方法对热泵的制热量进行测量时，通常采用测流量法测量空气的流量和截面平均温度。
