Difference between frequency conversion air conditioner and fixed frequency air conditioner
(1) The inverter air conditioner starts running with high power, quickly reaches the set temperature, maintains low power, keeps the room temperature balanced, cools and heats quickly, saves energy, and has little room temperature fluctuation.
(2) Constant-frequency air conditioners operate at a fixed power and maintain the indoor temperature through frequent switching, so the cooling and heating speed is slow, which has a great impact on the household power grid and the room temperature fluctuates greatly.
