摘　　要：变频技术应用在大容积风冷冰箱上时,通过试验验证,得到变频压缩机在稳定环境温度下稳定运行时保持一个额定的频率,比根据负荷不同频率一直变化时耗电量要低。因此,实现变频冰箱的整体匹配,关键在于确定变频压缩机在给定环境温度下的最佳频率点,以及在此条件下,冷冻风扇的转速最佳。When the technology of frequency conversion is used on the large volume frost free refrigerator, there are two kinds of operation methods of the inverter compressor. It runs either in the rated frequency or in the variable frequency according to the different load, when the environment temperature is stable. Through experimental verification, the power consumption of the former is lower than the later. For achieving the overall system matching of the, inverter refrigerator, the key is to confirm the best frequency point of the inverter compressor under a certain environmental temperature period, and to confirm the best rotational speed of the frozen fan.
