Why the preset temperature will be 24 ºC for AC in India?

Why the preset temperature will be 24 ºC for AC in India?

A month ago, The Union Power Ministry of India released a statement, according to it in all the government offices and complexes, the recommended temperature will be 24 °C for the AC that means they have to use AC at the recommended temperature in the normal condition. The Power Ministry also advised AC manufacturers to set the default setting in ACs at a temperature of 24 °C. In this post, I will discuss, Why the preset temperature will be 24 ºC for AC in India? So, let’s get started.

Why 24 °C?

“When the temperature for the AC is set at 24 °C as compared to 18 °C, 36 % electricity is saved. It is good for health and for the budget. AC manufacturers are also happy with the step,” Union minister RK Singh said. “Normal human body temperature is approximately 36-37 °C, but a large number of commercial establishments, hotels, and offices maintain a temperature around 18-21 °C. This is not only uncomfortable but is actually unhealthy.”

Suppose, you have a 1.5-ton AC, it will consume approximately 1 power unit/hour. 1 power unit corresponds to approximately 0.98 kg of Carbon Dioxide emission into the air. On average, ACs run for about 8 to 10 hours/day. So in total, the average AC is responsible for almost 10 kg of Carbon Dioxide emission every day.

Split AC

Increasing the AC temperature from the average of 22 °C to the now recommended 24 °C will reduce the energy usage by at least half a unit over the course of the day. That reduction of energy usage by even half a unit will make a considerable difference from both financially (by 3-5 % decrease in the electricity bill) and from the environmental perspective (half a kg less Carbon Dioxide released into the atmosphere).

Well frankly speaking it’s not about only 24 °C. The higher the temperature the less power would be consumed. But if you want a balanced combination between decent cooling and less power consumption then using your AC at 24 °C is a great deal, that’s why the government recommended it.

How setting the temperature to 24 °C will save energy?

In hot weather condition especially in summer, the temperature raises up to 45 °C or even more in the most part of our country. Suppose in case-1, you set the AC temperature to 16 °C and in case-2, it is 24 °C.  So the temperature difference is 29 °C in case-1 and 21°C in case-2, 8 °C less than case-1.

When you switch on the AC the thermostat identify the temperature difference and the compressor of the AC starts working immediately and it continues to work until the temperature reaches to the preset temperature ( or the temperature difference reduces to 0). You can easily understand that compressor has to work more in case-1 than from case-2.

Generally, the compressor operates on too much power like 2000W-3000W or even more. And you can easily calculate the power consumption by it after reading this article. If you want to save more power then you can install inverter AC instead of normal AC. You can also easily understand the difference between the inverter AC and a normal AC by going through this article.

And I think it has no significance that you use a quilt or a blanket after chilling the room to 16 °C. You can use simply a lightweight blanket instead of a quilt. In this manner, you can save some power for sure.

As per the findings of the Bureau of Energy Efficiency (BEE), the total connected load in India due to air conditioning will be 200 GW by 2030 going by the current market trends. This may further increase as only 6 % of households in the country are using air conditioners today.

The word “default” created a buzz.

After the announcement of the statement, the users on social media reacted immediately. The reactions being mixed. Some users welcomed it but some people criticised the move while others blamed the media for presently the report incorrectly. This happened due to the media used a world “default”. I would like to tell you that “default” means you can’t play with the settings means you can’t alter the settings. Which was totally wrong.

Dr. Atul Kumar, a professor at the Department of Energy and Environment at the TERI School of Advanced Studies in New Delhi, clarified the word “default” in the government notification. The ministry mandates that new ACs have a default setting of 24 °C, which does not mean that we have to maintain the temperature at 24 °C, but only that this should be the default temperature when the AC is switched on.

Note: Some countries like Japan have put in place regulation to keep the default AC temperature at 28 °C.

In my opinion, this is a great step taken by the government and we should welcome this decision. We should welcome those decisions in which goodies come in favor of the country first. Frankly speaking, I always operate my AC at 25 °C and the electricity bill doesn’t bother me so much. Well, this is my own personal opinion and other’s opinions may differ.

So that’s it for today guys. I hope you would have enjoyed it. If you have any suggestions and queries related to the post, let me know in the comment section below. Please do share this post to your circle to explore the knowledge you must know.
