However, according to experts, if used unreasonably, this method can cause energy waste and affect health.
In fact, fans do not reduce room temperature like air conditioners but only help circulate air. According to the US Department of Energy, using ceiling fans or standing fans with air conditioners can help cool air be distributed more evenly in the room, so users can increase the setting temperature while still ensuring a comfortable feeling. This contributes to a significant reduction in electricity consumption.
From a health perspective, cold winds blowing directly into the body for a long time can cause dry skin, irritation of the respiratory tract or muscle pain, especially when sleeping. Therefore, users should let the fan rotate or head up to the ceiling to disperse the cold air, instead of blowing directly into the body.
In addition, refrigeration experts also recommend closing the doors of the room to avoid losing cold air. If the room is not closed, the fan may accidentally push cold air out, causing the air conditioner to operate more, leading to power loss.
Regular cleaning of air conditioners and fans also plays an important role. Dust filters not only reduce cooling efficiency but also affect air quality in the house, posing a potential risk of respiratory diseases.
Combining air conditioning and fans is a smart solution in the hot season, but it is only truly effective when used scientifically. This is also a way to help families save electricity costs and protect their health for a long time.
