A standard air conditioner's temperature should be set to 25 to 27 degrees for cooling in summer, and around 18 to 20 degrees for heating in winter. This is to ensure maximum energy efficiency from your unit.
Studies by various agencies prove that setting the temperature at 27-degree celsius can reduce the AC bill by up to 30%. As per researches, every degree of temperature increased results in a 6% decrease in the energy consumption for a split AC.
Choose the right temperature
As per the Bureau of Energy Efficiency (BEE), the ideal temperature for the human body is 24 and any AC will take less load to achieve that target. So, it is better to set the AC temperature around 24.
It is always better to run AC at 26+ degrees and put the fan on at slow speed. 28 plus degrees is better. This will cost less electricity and your body temperature will also be in the range and there will be no ill effect on your health.
“What temperature should air conditioning be set at in summer” Direct energy recommends keeping your home's temperature set to 78 degrees f (25c) to get the most out of your electricity bills in the summer.
According to the Department of Energy1, 78° Fahrenheit is the sweet spot for air conditioners to balance energy savings and comfort when people are at home and need cooling. But in reality, this is a question that doesn't have a “one size fits all” answer.
End of dialog window. A move by the power ministry to increase the default temperature in air conditioners to 24 degree celsius will help you save almost Rs 4,000 on annual electricity bills, apart from reducing energy consumption.
Comfort temperatures
Owing to variations in humidity and (likely) clothing, recommendations for summer and winter may vary; a suggested typical range for summer is 23–25.5 °C (73–78 °F), with that for winter being 20–23.5 °C (68–74 °F).
For most people, a bedroom temperature of around 65°F (18.3° C) is ideal. This temperature may make it easier to fall asleep and improve sleep efficiency.
Having a good night's sleep can get you many health benefits for your body, skin, and even your nervous system. One of the ways to sleep better is to set a comfortable temperature for your room. The experts found that the ideal bedroom temperature is 25°C.
28°C is considered a warm temperature. It is equivalent to 82.4°Fahrenheit.
When the fan mode is turned on, the air conditioner works just like a regular fan. The blower of the unit will work whereas, the compressor unit is off. You can save a lot of energy in this mode as the compressor which is the most power-consuming component of the air conditioner is turned off.
Summer – 26 to 27 degrees Celsius is usually recommended. However, due to sometimes persistent cold snaps, it would be wise to consider adjusting it to the winter temperature settings. Winter – 20 degrees Celsius is enough to keep a comfortable interior without using too much energy.
Running in temperatures between 26-31°C
Your only alternative is to slow down. 'When air temperature exceeds 26°C and the humidity exceeds 70 per cent, performance drops markedly,' says Armstrong. Training your body to do its best under these conditions requires dedication.
This translates from 20.2º C to 24º C in winter and from 24º to 26.9ºC in summer. Thus, by ASHREA standards, which is an organization of HVAC engineers and designers, 27º C is on the high end of ideal if you are cooling a room, and if you are heating a room, it's 3º C above the highest ideal temperature.
Research has found the ideal sleeping temperature is around 17 to 19 degrees Celsius.
Chris Harvey, a heating specialist at Stelrad,further explains that 'leaving the AC running throughout the night can lead to unnecessary energy consumption and increased utility bills. Turning off your AC at night can prevent unnecessary strain on the system too, and optimize the performance of your heating.
Start by setting your air conditioner high
And, the best spot to do it at is 78 degrees Fahrenheit. According to Energy Star, it's an ideal temperature. 78 degrees keeps you fairly cool and comfortable during the day. It also shouldn't make your electric bill skyrocket.
No, It's a cozy warm temperature. Anything above 26 would be considered hot. 24–26 is warm, 20–24 is perfect, 15–19 is mild, 10–14 is cool, 5–9 is chilly , 0–4 is cold and anything below is frigid.
What Is An Unhealthy Room Temperature? For babies, pets, and the elderly, or for those who suffer from respiratory, lung, or heart disease, anything below 68 degrees and anything above 74 degrees for a prolonged period of time can cause serious health concerns.
Temperatures For a Comfortable Home & Good Overall Health:
Health professionals recommend keeping your home between 20 and 26 degrees Celsius (68- and 78 degrees Fahrenheit) depending on the season in order to maintain a healthy indoor environment.
Lower level isn't cooler
The optimum temperature setting for the human body is 24 degree C and hence such settings will be beneficial to consumers both in terms of financial savings and personal health,” explains Salian. Currently, there is little awareness about the most conducive set temperature in an AC.
While the DOE recommends 78 degrees Fahrenheit for the air conditioner temperature in summer, everyone has different comfort levels. Most air conditioning suppliers will recommend a setting of between 72-78 degrees Fahrenheit while you are in the house.
Why 24 degrees? This 24 degrees has been selected to save electricity. According to studies, for every one degree we raise the temperature of the AC to, up to 6% electricity can be saved.
If your area is currently at the design temp, your AC should run the “average” 12-16 hours per day. If it is five degrees higher, it will run 14 to 20 hours per day. At 10 degrees over, it will run 16 to 22 hours per day. At 15 degrees over, it will most likely run all day.
