小型风机的特点及其在制冷空调设备中应用的注意事项

Small-sized fan characteristics and application points for attention

小型风机虽然效率较低，但在制冷空调设备等小型家用电器中应用却很广泛。通过论述造成小型风机效率低的原因，指出了小型风机在制冷空调设备中应用的注意事项以及提高其运行性能的措施，并强调应力加强小型风机技术的研究。

Small-sized fans have been used wide-spreadly in refrigerating and air conditioning equipment although they have a low efficiency, so it is necessary to raise their efficiencies Therefore, the paper analyses why the small-sized fans have poor efficiencies and gives measurements to resolve it and points for attention when applying them for refrigerating and air conditioning devices.
