A non-inverter type air conditioner is a basic model which operates at a fixed speed. It simply controls the temperature by switching the compressor on/off alternately. The non-inverter types are commonly sold in stores and these are significantly cheaper to buy but consume up to 40% more electricity.
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. (But, even though, it is still more energy efficient on heating than any other barheaters, oil-heaters or gas-heaters)
A non-inverter air conditioner uses more energy than an inverter air conditioner. This is perhaps its most important detraction, especially in a world where we are meant to be constantly seeking ways to use less energy.
Also, the non-inverter air conditioner is less successful in achieving a constant or level temperature than its cousin, the inverter air conditioner.
When it comes to the financial side of things, the non-inverter air conditioner has an advantage; it is much less expensive than the inverter air conditioner. The non-inverter air conditioner is considered a good option for those who only need to use an air conditioner for part of the year; this is because the potential savings in energy are not so great compared to a scenario where it needs to be used more frequently.
An inverter type air conditioner has a variable-speed compressor which constantly regulates its speed to match to the desired temperature. This results in a more economic method of operation and energy-efficiency. Even though the inverter type units are more costly to buy, inverter units offer a wise long-term investment due to their energy efficient operation.
The inverter air conditioning units have increased efficiency in comparison to traditional air conditioners, extended life of their parts and the sharp fluctuations in the load are eliminated. This makes the inverter AC units quieter, with lower operating cost and with less broke downs. The inverter AC units might be more expensive than the constant speed air conditioners, but this is balanced by lower energy bills. The payback time is approximately two years depending on the usage.
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. EcoAir inverter air conditioning use between 30-50% less electricity to operate.
