Inverter air conditioner. |
摘要 |
<p>An inverter air conditioner controller includes an ac/dc converter 4 for changing ac power into dc power, a dc/ac inverter 6 for changing dc power into ac power having a desired frequency and a desired voltage to drive a compressor 7, compressor lock presumption unit 25 for presuming whether a compressor lock occurs, and frequency increasing unit 22 for increasing the operational frequency to a desired value. When it is presumed that compressor lock occurs, the frequency is determined so that an operational current value reaches an overcurrent detection level, and a lock protection unit activates an overcurrent breaker to stop the compressor. <IMAGE></p> |
