Experts suggest that sealing doors while using air conditioning for extended periods can have adverse effects on health due to poor air circulation and trapped harmful gases. An effective solution to this issue is installing an additional exhaust fan.
1. Is a Ventilation Fan Necessary in Air-Conditioned Rooms?
Many individuals hold the simplistic belief that temperature control units improve air quality, resulting in a healthier environment. While partially true, this assertion only holds when air conditioning is used judiciously and accurately. According to experts, prolonged use of air conditioning with sealed doors can detrimentally affect health by hindering air circulation and trapping harmful pollutants. Installing an extra ventilation fan is recommended to mitigate this problem.
To maintain health and ensure an adequate oxygen supply for respiration, a low-capacity fan should be positioned opposite the evaporator coil to expel stale air from the room. This facilitates the entry of fresh air into the room, providing oxygen for occupants. Standard installation guidelines dictate that each air conditioner should be equipped with a ventilation fan to facilitate air circulation and renewal within the room. The air conditioner itself draws air from the room for cooling, resulting in stagnant air. The role of the ventilation fan is to promote air circulation and renewal. However, due to inaccurate advice or concerns about increased electricity consumption, some users often overlook this component.
Additionally, a drawback of air conditioning is its tendency to dry out the air, leading to dry skin, dehydration, and symptoms such as sore throats and headaches. Therefore, if feasible, acquiring a humidifier or misting fan to humidify the air in the room is advisable. In the absence of these devices, it is advisable to refrain from operating the air conditioner in Dry mode. Another viable solution is placing a small water basin in the room to increase humidity levels in the air. For larger rooms, using an oscillating fan to push hot air upwards for the air conditioner to filter, while circulating cold air downwards, is recommended.
