V stands for ventilation in HVAC. With proper ventilation, you can maximize comfort in your house. In this article, I’ll briefly talk about the basics of ventilation and its impact on your comfort. 


What is Ventilation?

You’re maybe familiar with heating, cooling, and humidification. But you may not know what ventilation is. Ventilation is a process where outside air replaces the indoor air. With proper ventilation, you’ll get clean and fresh air.

Ventilation can be done in two ways – mechanically, and naturally. Without proper ventilation, you won’t get fresh air, and you’ll feel uncomfortable. Also, if you’re stuck in a room where there’s no ventilation, you’ll feel sick, and you may have to admit in the hospital. Also, when there’s no proper ventilation, you’ll face odor and humidity problems.

If you live in an old house, outside air can enter your house through the leakage of the air ducts. This way, you’ll get outside air, but it’s not the proper way of getting fresh air. When outside air enters your home through leaks, it’ll reduce the efficiency of your HVAC system. Besides, when there’s a leak, your HVAC system will consume more electricity in order to produce the desired heating and cooling. Again, in winter, this leakage problem will be severe. Through these leaks, outside cold air will enter your space and feel you cold. That’s why proper ventilation is important. With proper ventilation, you can have the highest level of comfort in your house.


Types of Ventilation

As I mentioned earlier, there’re two types of ventilation. Now, I’ll describe these two types briefly.

1.       Natural Ventilation

In natural ventilation, outside fresh air enters your home through vents and windows. But unfortunately, natural ventilation doesn’t work for some houses. Natural ventilation can cause a humidity problem in the house. However, some homeowners in the US prefer natural ventilation for fresh air as this ventilation process is free of cost.

In natural ventilation, you’ll have to consider the outside wind and the pressure difference between the outside air and indoor air. Also, when you’re planning to have natural ventilation in your house, you’ll have to place the ducts and windows in the right place. Otherwise, your ventilation system won’t work. That’s why most architects and engineers prefer mechanical ventilation over natural ventilation.

2.       Mechanical Ventilation

Here the ventilation is done mechanically by using ducts, exhaust fans, etc. For example, your ceiling fan works as mechanical ventilation. In mechanical ventilation, engineering simulation can play a vital role in finding out the right spot for ventilation. After using engineering simulation and determining the ventilation rate, HVAC technicians can identify the perfect spot for ventilation, and install it there. That’s why mechanical ventilation is more effective than natural ventilation, especially when it comes to your comfort.

2 Types of Ventilation

Now, let me talk about the impacts of proper ventilation on your comfort.



Impacts of Proper Ventilation on Your Comfort

Fresh Air

When it comes to your comfort, fresh air is important. Without fresh air, you’ll feel sick and end up admitting to the hospital. For example, if your room is located next to a gas station or restaurant, you will want to prevent the odor from coming out of the gas station, or restaurant. For this, you’ll need proper ventilation. If you don’t design the ventilation system properly, the odor will enter your room. But unfortunately, in this case, natural ventilation won’t work.

To get fresh air, you’ll need mechanical ventilation. You can call professional HVAC technicians to locate the right spot for the ventilation, and install the ventilation system.

When you’re locating the right location for ventilation, you’ll have to find the right location for the exhaust too. Without a proper exhaust system, you’ll damage your building or bother your neighbors.

Controlling the Fresh Air

Too much outside air can negatively impact your HVAC system. When there’s too much outside air coming into your house, your HVAC system will consume more electricity to reach the desired temperature. In the process, your comfort will be hampered. Also, because of this, your HVAC system can shut down completely.

You can control the outside air by using mechanical ventilation. It’ll automatically adjust how much air to go inside your house.
