2. The inverter air conditioner starts to save electricity within 1 hour.

At first, the inverter air conditioner works at the highest frequency, and the power consumption is the largest at this time; After more than ten minutes, the frequency is automatically changed with the change of room temperature, and it gradually runs at a lower frequency. At this time, the power consumption gradually decreases; About 30 minutes, when the room temperature reaches the set value, it will run at the lowest frequency. At this time, the power consumption is the smallest, which can be a fraction of the highest frequency (products before 2008) to a dozen (products after 2008).
