What is the Difference between Inverter and Non Inverter AC Technology?

Diff between inverter ac and non inverter ac power consumption difference between inverter ac and normal ac idea of saving electricity means that you should only use it when necessary and avoid ruining it. This means doing simple things, such as turning off the lights when you leave a room, as well as more involved processes, such as replacing standard light bulbs and devices that use less electricity.

If you do not see much impact on your daily life, when you make such changes, the impact on the environment of your actions will be huge. Further, we will discuss about difference between inverter and non inverter ac. However, let’s look at what is difference between inverter ac and non inverter ac and how is it different from a non inverter air conditioner.

How does an air conditioner work?

 Inverter and Non Inverter AC

For most people, the air conditioner simply throws cool air conditioner temperature it is set to. Different between inverter ac and non inverter ac are usually they work in summer season. But does it really work that way? In fact, during the cooling process, the air conditioner takes in the indoor air, cools it by passing it through the evaporator, and throws it back into the room. It is completely the opposite of how our good old air coolers worked.

Air coolers used to take in outside air, cool it with water and throw it in. But air conditioners simply work on internal air. Together with the evaporator, the air conditioner also has a compressor that compresses the gas (coolant) into the alternating current to cool it which in turn cools the incoming internal air from the room

Inverter air conditioner vs non-inverter air conditioner

What are Inverter air conditioners?

The compressor is off or on. When switched on, it works at full capacity and consumes the full power it is designed to consume. When the thermostat reaches the temperature level set in AC, the compressor stops and the fan (in AC) continues to operate. When the thermostat detects that the temperature has risen, the compressor will restart.

Inverter ac and non inverter ac power consumption. The compressor is off or on. When switched on, it works at full capacity and consumes the full power it is designed to consume. When the thermostat reaches the temperature level set in AC, the compressor stops and the fan (in AC) continues to operate. When the thermostat detects that the temperature has risen, the compressor will restart. 

What is inverter ac and non inverter ac? The inverter ac window technology in ac works like a gas pedal in a car. With this technology, the compressor is always on, but uses less power or more power, depending on the temperature of the incoming air and the level set in the thermostat. The inverter ac best in speed and power of the compressor are adjusted. Inverter ac means that this technology was developed in Japan and is successfully used for refrigeration and air conditioning there. This inverter ac split technology is currently only available in split air conditioners.   

What is a Non Inverter Air Conditioner?

An air conditioner without an inverter has a compressor motor with a fixed speed. Unlike inverter units, they work according to an “all or nothing” principle, which means that the compressor is automatically switched on and off instead of running at full speed all the time. The compressor automatically switches off when the desired temperature is reached and resumes when the temperature rises. Due to the frequent on / off cycle, the compressor always works with a high power that produces full noise while running, which sometimes consumes more power, making them less energy efficient than their counterparts.   

What are the advantages of inverter and non inverter ac?

inverter ac benefits

An AC 1.5 tons is designed for a certain size of the room and 1 ton ac for a different size. But not all rooms are the same size. A normal air conditioner with a capacity of 1.5 tons always works at peak power when the compressor is running. An air conditioner with ac with inverter technology will work continuously, but only draws as much power as is needed to keep the temperature stable at the desired level.

So the type of capacity adjusts automatically based on the needs of the room it is cooling. As a result, much less electricity is used and fewer units of electricity are used. Although air conditioner with inverter technology adjusts its capacity based on the required space, it is very important to install the right size air conditioner in a room. Make sure you evaluate the capacity of the room and the air conditioner before you make a purchase.

Customize the variable speed air conditioner

Air conditioners with inverter technology ac are variable speed / variable tonnage air conditioners and are therefore quite operationally different from regular air conditioners with single speed and single tonnage compressors. Fan speed in air conditioner with inverter technology adjusts their speed/tonnage depending on the heat load of a room. While regular air conditioners do not.     

Each room has a different heat load, even if they have the same size. Air conditioner fan speed control and the heat load depend on various factors as we mentioned in our article: things that influence electricity consumption in air conditioners. To give you an analogy, every person is different; even then the waist sizes of most of the trousers available on the market are fixed (leaving the elastics behind).

Inverter technology ac is just like pants with an elastic waist that can adjust to the size. The other advantage is that even if the waist becomes larger or smaller, the elastic pants adjust accordingly. Normal air conditioners have a fixed size. 

Based on BEE power consumption data, AC inverters with BEE 3-star ratings are about 7% more energy-efficient than BEE 3-star non-AC inverters.

The heat load in a room does not remain constant and varies with the seasons, varies based on the number of people, varies from day to night, varies based on climate profiles of your location. To take the same analogy that we have mentioned above, the waist size increases or decreases with the amount of food you eat or the amount of exercise you do. So because pants with an elastic waist can work well, an air conditioner with inverter technology can work well.

COOL DOWN ROOM TEMPERATURE WITH INVERTER AC

Several people worry that air conditioners and the speed air conditioning from the Inverter Technology will not cool properly or slowly. However, let’s take this image as a reference to understand how AC inverter works:

AC’S for non-inverters are fixed-speed ACs, while AC for inverters are variable-speed ACs. While inverter ACs have compressors that are always “On”. Since non inverter air conditioner are suitable for peak loads in the summer, they are all too large at other times (in fact, most people are even too large for the peak season). 

The disadvantage of the same is that the AC is usually “Overcooled”. So, if you set AC to a temperature of 25, it will be cooled to 23 or 22. Now you would wonder: what is the use of the thermostat? Well, the thermostat (in a non-inverter AC) switches the compressor off when the outside temperature has reached 25.

But a lot has happened before that. In an alternating current, refrigerant moves from liquid to gas (by taking heat from the room) and then back from gas to liquid when the compressor compresses it. But if the coolant is more and the heat in the room is less (which happens with extra-large AC), it does not get enough heat from the room to convert from liquid to gas and it continues to move like a liquid.

When the Difference between inverter and non-inverter air conditioning thermostat now detects temperature and the compressor switches off, the coolant still remains in the liquid state and therefore has the capacity to absorb heat from the room and convert it into gas. And so it takes more heat out of the room and cools the room below the set temperature.

For comparison:

The inverter technology AC changes the flow rate of the coolant based on the heat of the room. It never switches off the compressor. It only ensures that if the temperature setting is 25, it is maintained at that level.

Difference between inverter ac and non inverter air conditioner is: non-inverter AC would be too cool like in the picture. While inverter AC cools optimally. And so one may have the feeling that AC of the inverter is not cooling or slow.

Is there a Window AC with inverter technology on the market?

In 2018, LG and Voltas released new models LG JW-Q18WUZA and Voltas 185V DZA; these are Window AC models and have an Inverter Technology compressor. They have ISEER levels comparable to BEE 3-star rated split air conditioners.

Are there star ratings for AC inverters?

In 2016, BEE also introduced a new star score standard for Inverter Technology ACs. In 2018, all AC models of inverters in BEE 3, 4 and 5 are Star rating ranges at BEE. To find out more about new star rating standards for AC inverters, read this page on our website: Understand what ISEER is and star labeling of air conditioners for inverters in India.

Power Consumption of Inverter and non inverter air conditioners.

Less known benefits of Inverter Technology

Normal motors require 3-4 times more power (more than running power) when starting up. So the size of the inverter/generator required for an AC or refrigerator to work is considerably increased. But inverter technology air conditioners and refrigerators have variable speed motors that gradually require much less power when starting up. The required inverter/generator is therefore smaller.

For e.g. A fixed-rate 1.5 ton AC running on approximately 10 Amp current may require up to 30 Amp current at start-up and therefore a 5 kVA inverter/generator. But an air conditioner with inverter technology needs about 6-7 Amps of power and not much more at start-up, so a 1.5 kVA or 2 kVA inverter/generator is good enough to support it.

Normal motors have a much lower power factor. In commercial and industrial connections there is a fine for low power factor and discounts for higher power factors. A motor with inverter technology will have a power factor close to the unit (or 1), which not only results in lower electricity consumption, but also helps to get discounts on a better power factor.

If you plan to use solar PV for air conditioner, then it is best to use air conditioner or fridge with inverter technology, because it not only reduces the size of PV panels because it uses less electricity, it also reduces the size of the inverter together with the PV panel.

Inverter AC V/S Non-Inverter AC Power Consumption:

The comparison between inverter ac and non-inverter ac is further determined considering these points. Comparison between inverter ac and non inverter ac. For the various factors by which we compare the ac and non ac inverter?

Why Electricity Consumption important?

The idea of power consumption difference between inverter ac VS non inverter ac for saving electricity means that you should only use it when necessary and avoid ruining it. This means doing simple things, such as turning off the lights when you leave a room, as well as more involved processes, such as replacing standard light bulbs and devices that use less electricity. If you do not see much impact on your daily life, when you make such changes, the impact on the environment of your actions will be huge.

WHY WE ARE DOING  POWER CONSUMPTION OF AC?

  • The power consumption of ac of the equipment is equally determined by time, since it is determined by the wattage (* watt = power consumption in operating hours in hours). If a device was 10,000 watts, but you had it on for only 1 second, the power consumption would be just 2.7 Wh (watt-hour), which is about an hour of flashlight consumption (almost nothing). You can know that their importance is the same because power consumption = watt x is used.
  • There are devices with a high wattage and do not work long, such as toaster ovens, and most other devices are of the low wattage type and work for a long time. Both air conditioners and heaters are the worst because they have a high wattage and they work for a long time.
  • People often point to high power devices such as toaster ovens, boilers and more and think that they account for most of the electricity bill, but they don’t.

  1. Today, I went to the beachfront with my kids. I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is completely off topic but I had to tell someone!

  2. I just like the helpful information you supply in your articles. I’ll bookmark your blog and test once more right here regularly. I’m slightly sure I’ll learn plenty of new stuff right here! Best of luck for the next!
