What's an inverter?
An inverter is energy saving technology that eliminates wasted operation in air conditioners by efficiently controlling motor speed.
Air conditioners maintain set temperature by cooling when room temperature rises above the set temperature and heating when the room temperature falls below the set temperature.
Motor speed in non-inverter type air conditioners remains constant and temperature is adjusted by turning the motor ON and OFF, which consumes more energy.
In inverter type air conditioners, temperature is adjusted by changing motor speed without turning the motor ON and OFF.
Compared to non-inverter type air conditioners, air conditioners with inverters have less power loss and can save in energy.
When compared with a man running
1Non-Inverter Type Air Conditioner
Starting and stopping hard running, resting, then starting and stopping once again uses more energy.
2Inverter Type Air Conditioner
When an appropriate pace is maintained, a runner can continue without wasting energy.
How is motor speed controlled?
1Motor operates by magnets and electric current.
The motor consist of two types of magnets.
One is a permanent magnet that has a natural magnetic force.
The other is an electromagnet that produces a magnetic force by electricity.
2The direction of electric current determines polarity of the electromagnet.
The north (N) and south (S) poles of the electromagnet are determined by the direction of electric current.
When the direction of electric current is reversed, the north (N) and south (S) poles are also reversed.
3The motor rotates by switching direction of electric current.
When magnets come into contact, an attractive force occurs between the N and S poles of the magnets and a repulsive force occurs between the N and N poles and the S and S poles.
The motor rotates from the attractive and repulsive forces caused by the change in polarity of the electromagnet.
4The inverter is used to adjust the speed in which the direction of the electric current is switched, and this regulates the rotation speed of the motor.
The inverter rotates the motor by switching the direction of the electric current of the electromagnet.
Moreover, regulation of rotation speed in a motor is also performed by meticulously controlling the switching speed.
