An inverter is a piece of technology that saves energy by controlling the speed of the motor in an air conditioner in a way that doesn’t waste energy.
Air conditioners keep the set temperature by cooling when the room temperature goes above the set temperature and heating when the room temperature goes below the set temperature.
In air conditioners without inverters, the motor speed stays the same, and the temperature is changed by turning the motor ON and OFF, which uses more energy.
In inverter-type air conditioners, you can change the temperature by changing the speed of the motor without turning the motor ON and OFF.
Air conditioners with inverters lose less power and use less energy than air conditioners that don’t have inverters.
