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.
Starting and stopping hard running, resting, then starting and stopping once again uses more energy.
When an appropriate pace is maintained, a runner can continue without wasting energy.
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.
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.
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.
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.
