What is inverter air conditioning.

Inverter driven heat pumps speed up and slow down the motor compressor to suit energy demand and use a lot less energy because they follow the needs of the property more closely (see Image 1)

Because they don’t use a surge of energy to restart all the time they put less strain on the electrical supply making them better for single phase supply.

Inverter driven heat pumps can be ‘tuned’ to suit the climate in which they are operating

Benefits of inverter air conditioning.

At least 30% - 50% cheaper to run as it consumes less power

Far quicker to achieve desired temperature

The start up time is reduced by 30%

Much quieter

No temperature fluctuations, maximising comfort level

Advantages of inverter air conditioning.

Much more reliable in extreme temperatures.

Keep temperature constant (no fluctuations with room temp going up and down).

 Cost up to 30% less in electricity bills.  

The inverter air conditioner has less wear and tear on it (which can lead to a much longer life span)

Are much quieter than non-inverters




How does inverter air conditioning work.

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.

Permanent-magnet brushless DC motor within the rotor

The stator is driven by electronic switches (which replace the Carbon brushes), controlled by a micro controller.

Electronic system (hall effect sensor or software is used to recognize the rotor position)

AC operated (230Volts Single phase or 380/480Volts 3phase, 50/60Hz)




Efficiency.

Heat pumps are around 300% efficient. This means that for every unit of energy used by the heat pump in operation, three or more units of heat are generated for use in a building.
