How much electricity do air conditioners use?

The amount of electricity that air conditioners use can vary widely depending on several factors, such as the size of the unit, the efficiency of the system, the temperature settings, the size of the room, and the number of hours the unit is used.

The power consumption of an air conditioner is measured in watts (W) or kilowatts (kW). A typical window air conditioner with a capacity of 1 ton can consume around 800 to 900 watts of power per hour, while a split air conditioner with the same capacity can consume around 900 to 1000 watts per hour. The power consumption of larger air conditioners with higher capacities can be significantly higher.

To estimate the electricity consumption of an air conditioner, you can use the following formula:

Power consumption (in watts) = (Capacity of the AC in tons x 1000) / EER

Here, EER stands for Energy Efficiency Ratio, which is a measure of how efficiently the air conditioner uses electricity to cool a space. The higher the EER rating, the more energy-efficient the unit is.

It is important to choose an air conditioner with a high EER rating, as it can help reduce energy bills and save money in the long run. For more information on air conditioners, you can visit Shubz.in.


Here is a table showing the power consumption of air conditioners with different capacities and EER ratings:

Capacity (in tons)EER RatingPower Consumption (in watts)
0.753.3686
13.3918
13.5857
1.53.31436
1.53.51343
23.31836
23.51714

To calculate the power consumption of an air conditioner with a capacity of 1.5 tons and an EER rating of 3.5, we can use the following formula:

Power consumption (in watts) = (Capacity of the AC in tons x 1000) / EER

Power consumption (in watts) = (1.5 x 1000) / 3.5 = 428.57 watts

So, an air conditioner with a capacity of 1.5 tons and an EER rating of 3.5 would consume around 1.34 units of electricity per hour (assuming an electricity rate of Rs. 7 per unit).

It’s important to note that these are rough estimates, and the actual power consumption of an air conditioner may vary depending on various factors. It’s always a good idea to check the specifications of the particular air conditioner you’re interested in, as well as to consider the size and efficiency of your space and your own usage patterns, to get a better idea of how much electricity your air conditioner will consume.
