Inverter Technology
Air conditioner compressors are driven by motor, and motor rotation speed depends on power supply frequency. An inverter modulates power supply frequency to control motor rotation speed. Inverters stabilize temperature by adjusting compressor operation according to load to eliminate waste and save energy.
Even adopting an inverter to the fan motors of the indoor and outdoor units provides more precise control and contributes to energy savings.
Temperature Control by Inverter/Non-Inverter Compressors (Cooling)
When temperature is higher than set temperature, the motor rotates faster to lower room temperature.
Motor rotation speed is adjusted to maintain a constant temperature.
Motor rotates when temperature is higher than set temperature.
When temperature approaches set temperature, the motor rotation speed is reduced.
Motor stops when temperature is lower than set temperature.
Variation width for temperature becomes large when temperature is adjusted by repeatedly starting and stopping the motor. Furthermore, the motor always rotates at constant speed, and energy consumption increases from the energy loss of starting and stopping.
Lowering motor rotation speed according to load reduces both variation width for temperature and energy consumption.
