摘要： When inverter control is implemented in a refrigerator or the like, the rotating speed of a compressor motor is often operated at the preset minimum rotating speed. At this time, there has been a problem that when the DC voltage is boosted, the efficiency of the circuit drops due to switching loss in the power element. Still more, when the DC voltage is boosted even at the minimum rotating speed, the lowest voltage of the DC voltage must be controlled at 163 V or more including the fluctuation of the voltage. Therefore, there has been a problem in that the efficiency of the compressor motor also drops. To avoid these problems, when the temperature within a compartment of a refrigerator is cooled and approaches a preset temperature, and when a conduction ratio of the compressor motor falls below a preset value or a command on a rotating speed of the compressor motor becomes a preset rotating speed and the actual rotating speed also becomes the preset rotating speed, the control of the converter control circuit is turned off.

摘要翻译： 当在冰箱等中实现变频器控制时，压缩机电动机的转速通常以预设的最小转速运转。 此时存在直流电压升高的问题，由于功率元件的开关损耗，电路的效率下降。 此外，即使在最小旋转速度下直流电压升压时，直流电压的最低电压必须控制在包括电压波动在内的163V以上。 因此，存在压缩机电动机的效率也下降的问题。 为了避免这些问题，当冰箱的室内的温度被冷却并且接近预设温度时，并且当压缩机电动机的导通比低于预设值或者压缩机电动机的转速的指令变为预设值时 转速和实际转速也成为预设的转速，转换器控制电路的控制被关闭。

摘要： A high-efficiency, compact and low-cost electric power storage air-conditioning system incorporates inside its air-conditioner an electric power storage unit including a battery which is electrically interconnected to a d.c. system of the air-conditioner. Charging of the battery is controlled to be executed only during a steady operation of the air-conditioner when its load is light. Since a d.c. voltage of the battery is used directly as a d.c. voltage to drive the air-conditioner, a high efficiency, minimized loss and economical operation conditioning system is achieved.
