"Frequent ventilation" for corona prevention Energy saving with air conditioner on June 20, 11:03
This summer, frequent ventilation at home is required to prevent both heat stroke and new coronavirus infection. Air-conditioning industry groups are calling for more efficient use because it is more efficient to keep the air conditioner open when ventilating by opening windows.
A general household air conditioner does not have a ventilation function simply by circulating the air in the room, and it is required to perform frequent ventilation while using the air conditioner to prevent infection.
Regarding this, industry groups such as air conditioner manufacturers call for keeping the air conditioner open when changing the air in the room by opening windows or turning the ventilation fan.
Since the air conditioner uses the most power immediately after turning on the power, it means that power consumption can be reduced by ventilating with the power on without turning it off.
It is said that it is effective to keep the temperature setting at around 27 to 28 degrees, including during ventilation, and to ventilate the warm air inside the room and then turn on the air conditioner when returning home.
Tetsuji Okada, Managing Director of the Japan Refrigeration and Air Conditioning Industry Association, said, "If you do the basic things steadily, you don't have to worry much about the increase in power consumption, so I want you to use ventilation and cooling in parallel." I will.
