风管送风式空调(热泵)机组全年性能系数试验与计算方法解析

Analysis on test and calculation methods of APF for ducted air-conditioning (heat pump) units

分析GB/T18836-2017?风管送风式空调(热泵)机组》中定容型和非定容型风冷冷风型风管机APF试验工况的差异,以及风管机带机外静压和不带机外静压消耗功率的差异,并通过对试验样机APF的计算过程进行详细的解析,为研究人员理解标准中APF测试和计算方法提供参考。

The differences of APF test conditions between the single capacity and the nonsingle capacity air-cooled cold-air ducted air-conditioning (heat pump) units, and the differences of power consumption between the units with and without external static pressure, in GB/T 18836-2017 Ducted air-conditioning (heat pump) units, are analyzed. And the calculation process of APF is analyzed through test prototype. It provides references for the researchers to understand the APF test and calculation methods in the standard.
