← Back to Air Conditioners

Non inverter or fixed speed air conditioners 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.

Inverter air conditioning systems, vary the speed of the compressor and indoor and outdoor fans, delivering precise cooling or heating power as required depending on the desired indoor temperature.

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 conditioner 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. An inverter air conditioner uses between 30-50% less electricity to operate.
