Saving Energy with Inverter Air Conditioning Systems
Inverter air con vs. non-inverter is one of those puzzles that people considering air conditioning need to solve. When going out into the market place to research and your system, these are the two options available. The inverter air con vs. non-inverter question refers to the type of compression motor system running the air conditioning system. While inverter and non-inverter air conditioners do have a fair number of common characteristics, they are significantly different in the way the compressor’s motor regulates and controls motor the compressor.
People looking at reverse cycle air conditioning will come across an inverter. In this article, we will explain what an inverter is and discuss the pros and cons of inverter air con vs. non-inverter.
When any mechanical device starts up, there can be a spike or surge in the power usage. These power surges can result in higher running costs as the device uses so much power to start up. Any power hungry device will cause lights in the home to dim or flicker for a few seconds and this makes an air conditioning unit such as a non-inverter reverse cycle ducted type more costly to run.
An inverter is a little bit like the accelerator of a car. Instead of a massive power spike to start the “engine”, an inverter powers up gradually, consistently without any spikes, which means the whole start up event, is much cheaper and more environmentally friendly on electrical power. While it is impossible to accurately give cost savings, research shows that up to 30% in energy savings and running costs are achieved using an inverter system instead of a non-inverter unit. The inverter unit is more environmentally friendly which is a consideration these days.
Inverter systems usually run more quietly than non-inverter systems and have the benefit of better temperature control precision with fewer fluctuations. The initial cost of this kind of system if more expensive that a non-inverter system, but the pay back period is short and the energy savings gains make it a worthwhile consideration.
This kind of air conditioner unit does not have an inverter. Unlike the inverter type, it does not have the ability to change direct current into alternating (the accelerator effect example shown above). Another name for a non-inverter system is “fixed” air conditioning unit. The reason for this is that the amount of power is fixed and the speed at which it flows is fixed. Because there is no regulation of this current flow, the compressor must keep stopping and starting to regulate the energy flow to achieve the desired air temperature within the home.
While the non-inverter air conditioner is less expensive initially to purchase, it is more expensive to run especially in situations where the air conditioning is in constant use. It is ideal for a situation where it is not used constantly for example a holiday home or only for summer months.
