  • (8/11/16) Dũng Đỗ Việt

Exhaust fans are an optimal solution for families without air-conditioning conditions on hot summer days. Exhaust fans help your home air fresh, cool and clean. The installation of exhaust fans is quicker and easier than installing air conditioners, which saves you costs and still meets your family’s cooling needs. But installing the exhaust fan needs to be correct – a new technique to ensure its use. Here are some of the things that we would like to ask you to learn about installing wall-mounted exhaust fans. It is very important to install a ventilation fan or mounting direction, which partially makes your home space more comfortable. To install the first exhaust fan, it must be based on the size of the room and the conditions.

Normally, the common room, kitchen … need to circulate for 3-5 times per minute; work room, bedroom is less. To calculate airflow, you get 1-minute airflow divided by room volume. The bigger the fan, the more air can be transferred. Fans with a diameter of 90–110cm will cool a room of 20.9m2 while a 120cm fan and more can be used in larger rooms. Using multiple fans can work well in rooms longer than 5.4m. Small and medium fans will effectively cool within 120-180cm radius, while larger fans can be effective up to 300cm. The larger the wing will cool – at a smaller speed, the same amount as the smaller wing type. This is quite important in spaces where there are lots of papers or items that can be negatively impacted by strong winds. The fan must also match the aesthetic features of the room.
