本文记录了为一种先进的电动热泵开发高效室外空气移动器的努力。设计目标是将室外空气流动电力减半。850转/分的原型空气动力装置通过原型室外机输送3070 scfm（1449升/秒），通过盘管的压降为0.09英寸。（2.29毫米）的水和150瓦的电力消耗。整体空气流动效率估计约为35%，而传统应用的热泵风扇为19%。虽然这种空气移动器的成本是传统热泵空气移动器的两倍，但通过节能，这种额外成本应该在不到四年的时间内收回。该空气动力装置的声音等级（SRN）小于20。已经确定了将风扇效率提高5个百分点和电机效率提高2个百分点的方法。 5分，让风扇更安静。引文:研讨会，ASHRAE交易，1983年，第89卷，pt。华盛顿特区2B。

This paper documents efforts toward development of a high-efficiency outdoor air mover for an advanced electric heat pump. The design goal was to halve the outdoor air-moving electrical power. The prototype air mover at 850 rpm delivers 3070 scfm (1449 L/s) through the prototype outdoor unit with a pressure drop through the coil of 0.09 in. (2.29 mm) of water and consumes 150 W of electrical power. The overall air-moving efficiency is estimated at about 35% compared with 19% for the conventionally applied heat pump fan. Although this air mover will cost twice as much as the conventional heat pump air mover, this premium cost should be recoverable in less than four years through energy savings. The sound rating (SRN) for this air mover is less than 20. Means have been identified for improving fan efficiency by 5 percentage points and motor efficiency by 2.5 points and to further quiet the fan.
