Inverter AC VS Non Inverter AC

This article aims to explain simply the difference between an inverter and non-inverter AC system and the benefits of each type to help you decide which is best for your own particular air conditioning needs. 

To begin to explain the difference between both types, it is first necessary to understand what an inverter is. An inverter is an electronic device that converts direct current (DC) into alternating current (AC). Direct current is an electric current that flows in one direction only. Alternating current reverses direction many times per second. This alternating current is mostly used for power supply. 

Non-inverter Air Conditioning

Non-inverter air conditioning units are often known as “fixed” devices because the power supply does not fluctuate and it flows at the same speed. Because of this, the compressor in the system has to continually stop and start to maintain the desired cooling temperature as it is receiving a constant power supply. 

The result of this is that non-inverter air conditioning systems waste a lot of energy as the direct current cannot be regulated. This unnecessary usage of the compressor means it will not last as long and will require more regular maintenance and replacement parts. The non-inverter air conditioning system does not have the green credentials of its inverter counterpart. 

A non-inverter air conditioning system however is less expensive for the initial outlay and purchase, so may be a good option for areas and spaces that only need to be air conditioned for part of the year. Less regular use in ways counterbalances the extra energy use required.

Inverter Air Conditioning

Inverter AC is more expensive to purchase initially, but the extra investment is worthwhile when looking at long term energy savings across the board. It is also a more attractive option for those businesses and individuals that value products that are energy efficient and environmentally friendly. High performance comes at an affordable price with these systems. 

An inverter air conditioning system works by varying the speed of the compressors, due to using alternating current. This allows the system to produce precision cooling or heating delivery when required. Whenever an increase in heating or cooling capacity is needed, high speed operation of the compressor kicks in, increasing refrigerant flow. When weather conditions are clement and cool outside, an inverter air conditioning system will reduce compressor output and regulate the temperature. 

Other benefits with an inverter system are up to a 50% decrease in energy costs due to operating efficiency, speed at which optimum temperature is reached and start up time reduction of 30%. Combined with a much quieter operation, inverter systems are very popular, especially as the comfort level is combined with no voltage peaks from the compressor.

As soon as you switch on inverter air conditioning, the compressor immediately begins operating at high speed to cool or heat a space swiftly.

As the desired temperature approaches the thermostatically programmed temperature, the compressor slows and thereafter maintains a constant temperature. Any fluctuations such as occur will be immediately regulated to bring temperature back to set point.

It is definitely worth considering both inverter and non-inverter air conditioning systems as they both have a lot to offer. Along with your air conditioning engineer, you can consider all options and weigh up the pros and cons of each type of system before making a final decision.
