Fixed Speed System
Slowly gets to temperature as output rating is fixed. Then turns on and off to maintain room temperature.
Increased output to achieve set temperature faster. Then varies the output to maintain a constant room temperature.
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 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.
