An inverter is energy saving technology that eliminates wasted operation in air conditioners by efficiently controlling motor speed. The heat pump motor works like the accelerator of a car to maintain a set temperature rather than stopping and starting the motor like traditional units. Compared to non-inverter type air conditioners, air conditioners with inverters have less power loss and can save in energy.
Consider a runner as an example:
Non-Inverter Type Air Conditioner
Starting and stopping hard running, resting, then starting and stopping once again uses more energy.
Inverter Type Air Conditioner
When an appropriate pace is maintained, a runner can continue without wasting energy.
