Natural ventilation will be included in a proper house design as much as feasible to lower the electricity costs while also conserving the environment. However, installing appropriate fans to maintain the air quality in residences is pure and secure for the people to stay, and it is unavoidable.
Ventilation Fans Vs. Exhaust Fans
Most people, along with many others, couldn’t tell you the differences between exhaust and ventilation fans off the top of heads. Many people believe that they are the same thing, but nothing could be farther from the truth. In both office and residential areas, each fan has a distinct function critical for delivering exceptional air across an area. This blog article aims to explain the role of ventilation fans and the differences between these two types of intake air fans. If the ventilation fan is not working perfectly, then it means that there is debris and dirt in the duct, so you should consider HVAC cleaning in Suwanee, GA, for cleaning the ductwork.
Dissimilarities Between Ventilation and Exhaust Fans
Each fan has the features that make it carry out its functions effectively. Exhaust and ventilation fans aim to provide the freshest, good air quality possible in the place where the contractors mount them. The key distinction between the two kinds of fans is how they function. An exhaust fan eliminates contaminants from the indoor air in a house or commercial area, whereas a ventilation fan brings fresh and clean air to the indoor place from outside. If you want deep cleaning, then air duct sanitizing Suwanee would be a great choice.
As the name indicates, Ventilation fans are used to vent the air from a commercial or residential environment. It allows fresh air to enter the enclosed environment from the outside area.
It circulates air throughout the apartment or a house, preventing people from breathing uncomfortable, oxygen-depleted air. If the contractor did not make proper ventilation, you and others would be forced to breathe stale air.
Exhaust fans eliminate impurities and toxins from the air to create good air quality. Smoke, dampness, dirt, and aromas are frequent pollutants and impurities. That intake fan can effectively eliminate the cooking smoke and humidity from the air of a bath or a shower. If the exhaust fans do not evacuate such impurities from the environment, your lungs may get potentially hazardous particles.
Volume Of Air Change For Ventilation Fans
As indicated by the air volume, the volume of the area determines the quantity of air that it needs to ventilate. People require different ventilation systems for their different spaces. Although, professionals advise that the kitchen should have a 12-hour air change.
If the kitchen area has a volume of 5,000 cu feet, a blower with 5,000X12=60,000 cu foot/hour (equal to 1,000 cfm) is necessary to achieve a 12-hour air change.
Cfm stands for cubic foot per minute and is commonly stated in the fan’s characteristics or specifications. However, during the design process, always ensure with your local authorities on the design standards.
Utilization of Fans for Ventilation
Here are some examples of ventilation fan uses that you can come across in your daily life.
The kitchen fan in the household is generally a tiny propeller fan that professionals mount on the kitchen wall or a window. When building or renovating your home, you will have to cut a hole in the wall for the wall-mounted kind.
Because there are so many different propeller fans on the marketplace, it’s always a great idea to check for one that meets your needs.
During summer evenings, while the outdoor air temperature drops more than the indoor air temperature, attic fans are helpful to suck in outside air into the house. Therefore, the internal area of the residence gets some cold air without the usage of air conditioning units.
By utilizing the cool air from the outside environment, blowers to cool the house minimizes the operational expenses. Many people commonly use propeller fans, having a cfm of at least two air rotations per minute. You can complete the ducting work by linking a few areas to a centrifugal fan.
These fans have a cfm strength of approximately 80,000 and can be useful to expel hot or corrosive gases in areas like factories. You must complete the ductwork for hood installation.
Choosing the Fans
Take the following considerations while selecting appropriate fans for your purpose.
- To avoid the noise that the fan produces from getting into the residence, place the fans on silicone, rubber, or another absorbent material. The placement of the fans is also important to make sure that they do not create excessive noise in places such as bedrooms and living rooms.
- Make sure you determine the number of air changes per hour and choose appropriate fans. If appropriate, seek the advice of a qualified expert to choose the fan.
Keep the following characteristics in mind when looking for a good ventilation fan.
- Power Consumption: It’s the fan’s power input, which determines how much electricity it uses.
- Sound: It is a calculation of the sound that the fan produces when someone turns it on. Values will vary depending on the manufacturer. If noise is your primary concern while running, look for a lower dB.
- Current: It’s the fan’s current intake. The most significant element to check for is the air volume (cfm or cubic meter per hour). Determine the cfm needs of the area to be vented and select the most suitable fan.
- The fan’s speed: It is the fan’s revolutions per minute.
- Assembly opening and Net Weight: Keep these specifications in mind when constructing the wall mounting hole.
