If you are considering buying an ac system, the latest and the most efficient innovation available in the market today is the Inverter Technology for AC. Inverter technology is developed in such a method that it can conserve 30-50% of electrical energy (units taken in) over a regular a/c. And given that 2016, BEE has begun to provide star scores to inverter innovation AC as well. And in 2018, BEE had combined the star rating levels of Inverter and non-Inverter ACs. Listed below, you will discover how much energy an inverter a/c unit takes in and the factors impacting energy intake in an ac.
Power Consumption Of Inverter And Non-Inverter AC System
Based upon data from BEE in 2018 (the levels are similar in 2021), listed below is the agent (typical) sample of power consumption of Air Conditioners of different tonnage and star ratings:
|0.75 Ton||1 Ton||1.5 Ton||2 Ton|
|1 Star AC (mostly non Inverter)||627||843||1246||1648|
|2 Star AC (mostly non Inverter)||596||800||1184||1626|
|3 Star AC (mix of Inverter and non Inverter)||542||747||1104||1448|
|4 Star (mostly Inverter)||464||645||945||1293|
|5 Star (mostly Inverter)||450||554||840||1113|
I. Comprehending Tonnage Of AC
A/c units are rated in tons. One ton amounts to 12,000 Btu per hour (3.517 kW). That is the quantity of heat required (288,000 Btu) to melt one ton of ice in a 24-hour period. Therefore 288000, when divided by 24, provides 12000Btu, which amounts to one ton.
II. Understanding Energy Efficiency Ratio (EER)
The Energy Efficiency Ratio (EER) is the ratio of output cooling energy (in BTU/hr) to input electrical energy (in watts) at a provided operating point. EER is generally determined with a 95 ° F (35 ° C) outside temperature level and a room temperature of 80 ° F (26.6 ° C) and at a relative humidity of 50%.
EER = (Cooling energy in BTU/ hr)/ (Electrical energy consumed in watts)
EER = (Cooling energy in kW/ hr)/ (Electrical energy consumed in watts)
* Either of the above solutions can be utilized based upon the local standard.

III. Understanding The Energy Star Ratings
Energy Stars suggests the performance of the ac system. More stars indicate greater energy efficiency. The below table indicates the star rankings and EER of the a/c unit.
Factors Affecting The Energy Consumption Of Air Conditioner
This is the basic calculation of AC power intake. There are a lot of elements that affect power usage:
I. Type Of AC
Because Inverter AC’s do not work at full power once the needed temperature is achieved, the blower operates at a lower RPM, reducing force usage.
If you switch on the AC and your room temperature is 30 degrees, when your required temperature level of 24 degrees is achieved, the inverter AC will reduce the RPM of the blower, and henceforth the power devoured will less compared to the time when AC was begun. We have also compared the power consumption of window and split ac in another article.
Here is the comparison chart of inverter AC Power Consumption vs Conventional AC power consumption.
II. Atmospheric Temperature
The temperature of your room is crucial, which will change every day, how hot is it outside and no matter whether you are living on the top flooring and the number of windows and sort of glass made use of as a part of it.

III. Running Hours
Running time per Day/Night, Since your dividers won’t be constantly warmed by the sun in the middle of the night, and your windows will not toss daytime and warmth in the room.
IV. Fan Mode
If your AC runs most of the time in fan mode, then electrical energy usage will decrease significantly.
V. Energy Efficiency Ratio (EER)
Each Air conditioner has a vigor effectiveness ranking that rundowns what variety of BTUs every hour is utilized for every watt of strength it draws.
For room AC, this score is the Energy Efficiency Ratio or EER. For focal Air Conditioners, this ranking is the Seasonal Energy Efficiency Ratio or SEER.
These rankings are published on an Energy Guide Label, linked in a prominent place on brand new Air Conditioners. Various AC producers are intentional members of the Energy Star calling system. High Star machines show that high EER and SEER ratings and thus reduced power usage.

VI. Energy Star Rating
Air conditioning unit designs with a rating of 1 to 5 stars are available in the market. A 5-star show spares the most severe savings, and the 1-star rated display expends greater power. A constant AC used for domestic use has a range of 5,500– 14 000 BTU/hour. Here is a chart of 1.5 Ton AC power consumption and saving monthly.
On the off opportunity that the environment is hot, purchasing an AC with a greater BEE rating is recommended. The ratings are approved by BEE (Bureau of Energy-Efficiency).
A few city locations are hot; some perspire and some chilly. An a/c unit finishes 2 things: cool the air and get rid of the humidity. In case a city is hot, a big part of the power is used up to cut down the temperature.
Be that as it may, a few city areas are damp yet not extremely hot (seaside areas) and due to the reality that the exchanging of the blower trusts temperature level. So a 1.5-ton AC in a comparative setup in 2 urban areas will devour distinctive power structures because the temperature levels are remarkable. The usage will be less in the city with bringing down the temperature level.
This furthermore raises a point that the tonnage of AC required for a room fluctuates crosswise over city locations. A muggier city does not require much cooling but rather requires a higher quantity of stickiness evacuation. Stickiness evacuation trusts the ideal opportunity for which blower runs.
In the event that the AC is larger than usual, the blower will keep running in short cycles and subsequently won’t have the capability to expel mugginess viably.
VIII. Electronics Apparatus In The Room
We frequently see that our laptops or PCs heat up after long activity. Undoubtedly, even mobile phones continue to get hot. All electronic and electrical machines radiate a warmth that will be cooled if Air Conditioner is turned on. Even knobs and lights send warm along with light.
