JAPAN: A survey conducted by Daikin found that the majority of Japanese consumers do not know how to use air conditioners efficiently, so they did not turn them on during the recent hot weather.

The survey was conducted among 527 men and women aged 20 to 59 in mid-June, when the maximum temperature in Tokyo exceeded 30°C. About 70% said they would refrain from using air conditioners due to rising electricity costs.

It also found that 59.2% of people misunderstand how to save energy with air conditioners. Common misconceptions included running the air conditioner at the lowest possible air volume, frequently turning off the air conditioner, and, incredibly, covering the outdoor unit.

Daikin claims that due to the way air conditioners work, any of these actions can easily lead to an increase in energy consumption.

The same survey, which is likely to produce similar results anywhere in the world, also showed that a large number of consumers do not know how air conditioners work. Almost 50% admitted that they did not know that the air conditioner cools the room by removing heat from the room to the outside.

Daikin claims that while air conditioners in Japan account for the majority of household energy use during peak summer hours, not using them can lead to heat stroke. He advises using the air conditioner correctly, and understanding how air conditioners work is important to save energy.

The Daikin Japan website now contains information for the general public explaining how air conditioners work and how to save energy.
