本文简要地叙述了空气焓差法和房间量热计法的原理,估计了这两种方法的误差、并比较了优缺点。作者建议在制订风机盘管标准时把房间量热计法定为性能试验方法。 This article briefly describes the principle of the air enthalpy difference method and the room calorimeter method, estimates the error of these two methods, and compares the advantages and disadvantages. The authors recommend that room calorimeters be stipulated as performance test methods in the development of fan coil standards.
