What is the difference between a fixed and inverter system?
 |

 |

Fixed Speed System
Slowly gets to temperature as output rating is fixed.
Then turns on and off to maintain room temperature. |
Fixed Speed
A fixed speed system only has a single speed compressor motor that is either on or off.
It works similar to a single speed fan heater running at its only speed that switches off
when the desired temperature is reached and switches on again when the temperature drops
to a set level. As there is only one speed that the fixed speed system can run at, it
takes a lot longer to get to the desired temperature. As such this tends to lead to a
lot more power usage in comparison to inverter driven systems. |

Inverter Systems
Increased output to achieve set temperature faster.
Then varies the output to maintain a constant room temperature. |
Inverter Technology
Inverter technology uses a variable speed compressor motor similar to a car. It simply
slows down and speeds up as needed to hold a selected comfort setting. This means the
desired room temperature will be reached more quickly and maintained more efficiently.
Inverter technology provides a more precise room temperature without the fluctuations
and power wastage of fixed speed systems. Inverter technology is significantly more
energy efficient with energy savings of up to 30% over fixed speed systems.
The speed control of the outdoor unit also means quieter operation, this is important especially at night in residential areas. |
