By increasing the working frequency of the air conditioner compressor, the inverter air conditioner has increased the low-temperature heating capacity, and the maximum heating capacity can reach 1.5 times that of similar air conditioners, and it can still maintain good heating effect at low temperature. In addition, the general air-conditioning split machine only has four speeds to adjust, while when the indoor fan of the variable frequency air conditioner is running automatically, the speed will change within the range of 12 speed with the operating frequency of the air-conditioning compressor. Because the rotation speed of the air-conditioning fan is reasonably and subtly matched with the energy of the air conditioner, the quiet operation with low noise is realized, and the lowest noise is only about 30 decibels.
At the initial stage of each start-up, the inverter air conditioner firstly heats or cools with maximum power and maximum air volume. When the inverter air conditioner quickly approaches the set temperature, the compressor of the air conditioner runs in a state of low speed and low energy consumption, and the set temperature is only maintained with the required power, which not only stabilizes the temperature, but also avoids the attenuation of service life caused by frequent start-up and stop of the air conditioner compressor, greatly reducing power consumption and saving energy.
