Inverter Air Conditioning
What Is Inverter Air Conditioning?
Not to long ago an air conditioning compressor had one speed – these are now referred to as non-inverter, fixed speed or conventional air conditioning units. Non inverter or Fixed speed air conditioning units deliver a fixed amount of power via a fixed speed. This means the compressor has to stop and start to maintain the desired room temperature. The unit was either turned off or running at 100%. Inverter air conditioning system, varies the speed of the compressors, delivering precise cooling or heating power as required. It is basically a variable speed motor.
Most air conditioning units these days have an inverter drive motor.
How Does An Inverter Air Conditioning work?
An Inverter is used to control the speed of the compressor motor, so as to continuously regulate the temperature. The Inverter units have a variable-frequency drive that comprises an adjustable electrical inverter to control the speed of the electromotor, which means the compressor and the cooling / heating output. The drive converts the incoming AC current to DC and then through a modulation in an electrical inverter produces current of desired frequency. A microcontroller can sample each ambient air temperature and adjust accordingly the speed of the compressor.
The amount of cooling or heating required by an air conditioning unit varies depending on the outdoor temperature and the amount of heat in the room.
When the cooling or heating capacity needs to be increased, the compressor will operate at a high speed and will increase the amount of refrigerant flow.
Conversely, during moderate outside temperatures for example, when the cooling and heating capacity needs to be decreased,the compressor will operate at a low speed and will decrease the amount of refrigerant flow.
When the inverter air conditioning is switched on, the compressor operates at a high speed in order to cool or heat the room quickly. As the room temperature approaches the set temperature, the compressor slows down, maintaining a constant temperature and saving energy. Any sudden fluctuation in the room temperature, will be sensed and instantly adjusted to bring the room temperature back to the set temperature. Inverter air conditioning use between 30-50% less electricity to operate.
Benefits Of An Inverter Air Conditioning Unit
- The inverter air conditioning unit has an increased efficiency in comparison to traditional air conditioning units. A 2.5Kw inverter unit (for example) can run between 1kw to 3.5Kw – depending on what is required.
- The life of the parts are extended.
- Quicker to achieve the desired temperature
- The start up time is reduced by 30
- No temperature fluctuations, maximising comfort level
- Much quieter
