Fixed-frequency inverter air conditioner air conditioning and the biggest difference is the use of the principle of different products on the compressor. Inverter air conditioner compressor can moderate the thermostat in the case of long-term open operation, if the room does not need a lot of hot and cold, the air conditioning will be in a state of low frequency operation, intelligent constant temperature, while the fixed-frequency products are needed in human It is the case of air conditioning in the switch adjustment. Overall, fixed-frequency air compressor frequently to open stops, the indoor temperature fluctuations, and the inverter compressor can change the speed due to open a significant reduction in the number of stops, the indoor temperature remained constant, constant temperature of the inverter air conditioner better comfort ; in energy efficiency, unlike the fixed-frequency inverter air conditioner as often start, will not produce a time of instantaneous large current, so the use of very energy efficient, according to statistics, more than the fixed-frequency inverter air conditioner energy-saving air conditioner about 30% -50%.
