Japan survey reveals A/C energy saving misconceptions, tips to cool electricity bills July 17

The unit determines the room temperature from the air around it, so it works effectively when the air in the room is circulated with a fan. (Mainichi/Tatsuro Ando) TOKYO -- Some 60% of people surveyed by major air conditioner maker Daikin Industries Ltd. have serious misconceptions about air conditioning power-saving techniques, as continuing scorching temperatures across Japan force people to keep the cool air on. With the extremely hot summer and electricity rate hikes hitting households this summer, what are well-intentioned air conditioner owners mistakenly doing that actually increases demands on the grid? Daikin queried 527 people aged between 20 and 59 nationwide via smartphone in mid-June. It gave four effective and four potentially counterproductive ways to "save energy," and asked respondents, with multiple answers allowed
ブランドスーパーコピー "Which do you think saves energy when you use air conditioners in the summer?" Response percentages were rounded down to whole numbers. The most common misconception, at 26%, was "To use 'low' airflow as much as possible." Daikin said that people often think that setting the A/C to "low," which does not make much noise, will reduce power consumption. However, it may take longer to cool the room, ultimately resulting in more energy used. Other misunderstandings included, "To cover the outdoor unit" at 22%, and "To turn off the A/C frequently" at 19%. Outdoor units account for more than 80% of an air conditioner's power consumption, and putting things on or around them means heat cannot escape efficiently, increasing the load on the units. And air conditioner energy use spikes just after they are turned on, so switching them on and off frequently may in fact increase power consumption. The outdoor unit of an air conditioner is seen on July 16, 2023. Power consumption can be reduced if there are no weeds or obstructions around the unit. (Mainichi/Tatsuro Ando) An experiment conducted by Daikin showed that "during the daytime, if you go out for about 30 minutes, leaving the A/C on saves energy rather than turning it off once." On the other hand, leaving the device on without considering when and how long one is away from home resulted in higher electricity consumption than turning it on and off often. It appears that the key to saving energy is making accurate estimates of time spent outside the home. The most prevalent effective power-saving method

Circulating cold air that accumulates near the floor apparently makes it easier for the air conditioner to correctly determine the room temperature. Daikin explains how air conditioners work and how to save electricity at its website (in Japanese).
