New coronavirus and heat What is an effective ventilation method? May 12, 19:25
In addition to the new coronavirus, it has become a season when heat is a concern. Leading building material manufacturers and air conditioning equipment manufacturers want to introduce effective ventilation methods to help spread infection and prevent heat stroke.
The point is "how to open the window"
“YKK AP,” a major building material manufacturer, has introduced on its website etc. an effective ventilation method using windows due to the spread of new coronavirus infection.
According to it, "open two windows from one place" "open windows in two directions", "it is more effective to ventilate on the diagonal of the room".
You can open two sliding windows
However, there are cases where there is only one window, such as a condominium in a dense residential area. In that case, you can ventilate by opening the indoor doors and windows of other rooms to create a passage for the wind, or by agitating the air with a fan.
Especially in the case of a sliding window that slides sideways, it is effective to draw air from two places by moving the window to the center and opening both sides.
Most air conditioners cannot ventilate
On the other hand, when it gets hot, it is necessary to use the air conditioner appropriately, but according to Daikin Industries, a major air conditioner, most air conditioners just circulate indoor air and cannot ventilate.
For this reason, even when using the air conditioner, he sometimes calls for ventilation by opening windows.
Ventilation with reduced power consumption
You may think that opening the window while using the air conditioner is a waste of electricity. The person in charge taught me how to ventilate while suppressing power consumption.
According to this, the power consumption of an air conditioner is high when the power is turned on, so do not turn off the power of the air conditioner you are using, but open the window with the air conditioner on.
In addition, since the air conditioner consumes more power when the temperature of the room rises due to outside air, it is important to open the window after raising the temperature slightly before ventilation.
Persons in charge of "YKK AP" and "Daikin Industries" said that they would like to use good ventilation to help spread infection and prevent heat stroke.
