The upcoming peak heat wave will surely make anyone living and working in big cities feel sick. It not only affects everyone’s pocket through electricity bills, but it also creates a feeling of fatigue, sluggishness, reduced work performance and health is also negatively affected.

During the heat wave, the road surface temperature can reach over 50 degrees Celsius.

Air conditioning is one of the very effective saviors for us this season, but the weaknesses of the air conditioner if not handled intelligently, it also creates bad effects on health.

One of the weak points that everyone knows of the air conditioner is that the closed air circulation is not supplemented with outside air, and this amount of air will be gradually withdrawn moisture, creating a dry feeling for the room.

The fact that the air does not circulate to the outside, combined with the continuous release of carbon dioxide by the human body, will make the air quality in the room decrease, and staying in an air-conditioned room for a long time will no longer feel comfortable.

Therefore, each air-conditioned room should be fitted with an additional ventilation fan to overcome the existing disadvantages of the air conditioner.

The benefits of installing a ventilation fan in an air-conditioned room

– Solve the problem of “fresh” air being brought into the room

Normally, we should install a ventilation fan in the direction of drawing old air from the room to the outside, this both helps to suck all the air containing a lot of CO2 out, and creates low pressure in the room, making the air fresh. forced to flow into the room through the openings.

– Helps the air conditioner cool faster

We also know, hot air will rise, cold air will sink. Therefore, an exhaust fan located at the top will help draw the hot air out of the room faster, the cooler air outside the room will be drawn in from the lower openings, so the average temperature will be lower. the room’s average is greatly reduced compared to when not smoking.

– Balance the humidity with the outside air

Air conditioners used for a long time will gradually reduce the humidity in the room, if you do not have the habit of opening the door when not in use, the humidity will be difficult to balance back to the outside. Humidity that is too low will cause the body to react, specifically the mucous membranes in the nasopharynx will dry out, making us easy to have a sore throat, too dry air also creates conditions for fine dust to fly more easily.

Therefore, the use of an exhaust fan will make the air humidity balance back to the outside environment before using the air conditioner.

Recommended usage

To use the ventilation fan effectively, we should turn on the blower for about 10 minutes every time the air conditioner is turned on. This will “reset” the state of the room to the freshest state to begin cooling.

If you don’t mind the hassle, it’s best to turn on the fan for 10 minutes every 3 hours whether or not the air conditioner is on. In addition, the inconvenience of having to watch the time to turn on this air conditioner can be completely solved thanks to smart switches with the function of turning off the device according to the scenario that can be purchased for about 150 to 200,000 VND.

The intake of air even when the air conditioner is not on will help us always have fresh air whether the weather is hot or not.

So how is it good to install?

– Installation location

Normally, the installation position of the exhaust fan should be in the opposite direction to the direction of the air conditioner and the minimum height is equal to the height of the air conditioner. Installing the air conditioner lower and near the air conditioner will cause the fan to suck both cold air and blow out of the air conditioner, reducing the efficiency of the machine.

– Choose the right type of fan

Most exhaust fans have parameters of the fan’s air flow in m3/h (cubic meters per hour). In order for the fan to absorb enough air in 10 minutes, we will need 6 times the volume of the room. For example, a room of 10 square meters is 3 meters high, the volume of the room is 30 cubic meters.

So we will choose a fan with a wind flow of 30 x 6 = 180 m3/h to ensure that in 10 minutes the fan can theoretically exhaust all the air in the room.

The calculation above is just for us to choose a fan that is enough to suck up all the old air in 10 minutes, in fact the exhaust fan will suck most of the air at the fan door, not all the air in the corners. preventable, so the calculation is only recommended, not required to have enough capacity.

In addition, to avoid heat loss when the fan is not in use, we should also buy an exhaust fan with a blocking door so that cool air does not leak out too much when the fan is not turned on.

Conclude

With only about 200 to 300 thousand VND for an exhaust fan, we will make the use of the air conditioner much more efficient, and the health of the user is also better guaranteed. But you also do not because of its comfort without going out to exercise, anyway, exercise is still much better for health.
