Inverter AC vs Non-Inverter AC – What is Better?

Summers can be truly devastating. That is an area that air conditioners have attempted to address. They have been observed to be one of the best options to fight the blazing heat. So far, so good. But, there are plenty of options available when choosing your air conditioner. One such crucial differentiating factor that you would come across when picking the best air conditioner is the Inverter and Non-inverter Air Conditioners.

So, how do inverter ACs and Non-Inverter ACs differ from one another? We will take up a comparison between an inverter and non-inverter air conditioner and understand which of them are designed to be a good option for your individual preferences.

The biggest difference between an inverter and non-inverter air conditioner is that an inverter air conditioner can regulate the speed of its compressor motor, i.e. it can have a variable speed. In comparison, non-inverter ac motors only run at full speed or stop.

Inverter AC vs Non Inverter AC

What is an Inverter AC?

An inverter air conditioner is an AC that has a compressor with variable speed. The compressor inside an inverter utilizes a variable speed motor which controls the flow of the refrigerant in the air conditioner as per the ambient conditions and actual requirements.

An air conditioner with the inverter technology does not shut down the compressor at all, unlike the traditional compressor. It will keep the compressor at all times – as long as your air conditioner is ON. However, the compressor will not run at a constant speed at all times. It will have a variable speed and thus control the flow of air and temperature. This will be helpful in maintaining the constant temperature inside the room, and it will never change a fraction from what you have configured it to.

What is a Non-Inverter AC?

A Non-Inverter Air conditioner is also referred to as a traditional air conditioner. As you would have understood clearly by now, a non-inverter air conditioner has a compressor that runs at a constant speed.

The compressor in a non-inverter AC will not keep running at all times. Instead, it shuts down when needed and restarts when the temperature goes above the one you have configured. The compressor will keep starting, compressing the refrigerant to expel the hot air and then expel it. Once the temperature reaches the pre-set level, it just shuts down, only to start when the temperature begins to increase.

Inverter AC vs Non-inverter AC – How do They Differ?

Well, to understand the difference between an Inverter AC and a Non-inverter AC, we will split the discussion into different aspects and factors. This will help us understand the differences more clearly.

Technology
An inverter is essentially a device used for changing the current type of current from AC to DC. In case of an air conditioner, an inverter is used for control the frequency of power supply to the compressor. This is done in tune with the need for heating or cooling the room.

An inverter air conditioner comes with a variable speed compressor. It regulates the heating and cooling as per the requirement. A non-inverter air conditioner is the one that does have a fixed speed compressor. A non-inverter air conditioner has a compressor that keeps starting and shutting down as per the needs, while an inverter air conditioner has a compressor that keeps running at all times – but at variable speeds.

Functionality

An inverter air conditioner comes with an adjustable speed that controls the flow of the refrigerant as per the requirements. It does not start and shut down frequently. This will help you get the pre-set heating or cooling, and the air conditioner does not require frequent resetting.

A non-inverter air conditioner delivers a fixed amount of power to the compressor. The compressor keeps stopping and starting frequently. The compressor will go off when the pre-set temperature is reached and will start when it changes.

Energy Efficiency

This is an area that should make a huge difference between an inverter air conditioner and a non-inverter air conditioner. The inverter air conditioner comes with an automated process when it comes to controlling the temperature. This will be helpful in saving enough in terms of electricity. You would find it one of the perfect options for energy-efficient design.

The non-inverter air conditioner, on the other hand, is not economical and non-energy efficient. The compressor keeps going off and on as per the requirements, and that is what would make it less energy efficient.

Noise

Well, an air conditioner is something you would NOT want to produce much noise on. An inverter air conditioner offers heating and cooling functionality based on the temperature inside the room and the ambient temperature. The compressor does not shut down and continues working at the moderate temperatures throughout the operation cycle. That would make it run quieter.

The non – inverter air conditioner is not efficient in handling the noise. It keeps automatically shutting down and starting frequently and thus can create a lot of noise. It can develop a lot of noise at times.

Cost Factors

Well, the cost of an inverter air conditioner is considerably more than what you would find on a non-inverter air conditioner. Of course, the smoother and quieter operation is what should compensate for the extra cost. Moreover, the inverter air conditioner offers an energy efficiency that would compensate for the cost further.

A non-inverter air conditioner, on the other hand, is less expensive. But, the installation of a non-inverter air conditioner is set to cost you more than what an inverter air conditioner would cost you.

Having checked the best features offered by the inverter and non-inverter air conditioners, let us compare them in a head to head comparison between the two:

How Much Electricity Does an Inverter AC Use? Inverter vs Non Inverter AC Power Consumption

The inverter air conditioners tend to save more energy than their non-inverter counterparts. Ideally, 1 star and 2-star air conditioners come with a non-inverter functionality.

The 1 star and 2-star non-inverter air conditioners will consume around 800 to 840 units of power if you are checking out the options in the 1-ton capacity. If you look at 4 star and 5-star air conditioners with the inverter capability, you will find that you get access to 550 to 650 Units of power.

That should give you an idea on how to pick the best air conditioner among the inverter and non-inverter counterparts.

Please note, however, that the figures above are based on the labels on a few select brands of air conditioners available in India. We arrived at those calculations based on the average ratings of each of them.
