Inverter Air Conditioning

Difference between inverter and non inverter air conditioning units

Non inverter or Fixed speed air conditioning 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 system varies the speed of the compressors, delivering precise cooling or heating power as required.

How a non inverter or fixed speed Air Conditioner works

This unit only has a single speed compressor motor that is either on or off.

It works similar to a fan heater that switches off when the desired temperature is reached and on again when the temperature drops to a set level.

How an Inverter Air Conditioner works

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 conditioners use between 30-50% less electricity to operate.

Benefits of an inverter Air Conditioner

Inverter air conditioning is more expensive than non inverter air conditioning but with the current spiralling energy costs, is it worth the extra money?

Let’s see what the benefits are of inverter air conditioning compared with a non inverter air conditioning:

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

N

Far quicker to achieve desired temperature

The start up time is reduced by 30%

y

Much quieter

g

No temperature fluctuations, maximising comfort level

M

No voltage peaks from compressor

All inverter air conditioning are heat pumps which in itself is one of the most energy efficient form of heating

Is it worth paying more for an inverter air conditioner?

In summary, an inverter air conditioning can reduce your energy bill. It will be worth paying more for an inverter air conditioning if you use your air conditioning all year round.

With energy costs now running at approximately R1.15 per kWh and still rising there is no doubt this will save you money in the long run.

There’s a but

To get these efficiency gains it is important to use the air conditioner as it is intended:

,

The unit has to be sized right for the room you are heating/cooling

It is best to run the unit continuously and set for the desired room temperature (i.e. such as 21 Celsius) and not at a full setting for heating or cooling (as most people do)

And of course – a well insulated, low-thermal mass house helps too…
