Proper ventilation keeps the home a safer aeration environment and offers cleaner oxygen supplies throughout the home. We need fresh breathable air for the survival of our own selves and these systems help us make that requirements possible. Our bodily metabolisms are dependent on the quality of air we inhale and exhale regularly and this article packed with info is your guide to such an important feature we must add in our home planning or making. Read well everyone, and stay updated in your journey of life and remember, always move forward no matter what; and we sincerely appreciate your efforts and we hope you win and learn from the inner and outer battles you silently and constantly fought every single day. May the supreme power give you strength. Love from this side 😊
1. Natural Ventilation
- Explaining the Wind: The movement of air is made possible by the rising and lowering of air temperatures in a given environment. When the air above the surface gets warmer, it creates a lower pressure in the area because the spacious air rises above slowly. The process continues as the air keeps rising high and it then cools down and moves towards where the water bodies are present and the area there becomes a place of high pressure and that pressure difference pushes cold air towards the land. This chain of movement of air results in the creation of wind.
- Single-Sided Ventilation: It means naturally ventilating the space of buildings or structures with limited areas by the use of openings on one side of the building. Due to structural constraints, this type of ventilation is also used in situations where cross ventilation cannot be much suitable. When it comes to natural ventilation systems, this type generates the least air circulation and its effects on the environment are so low.
- Cross-Ventilation: Adjacent or opposite wall openings are used and arranged for allowing air to enter and cross space from both the sides and exit likely from the opposite direction. Buildings located in climates with higher temperature zones usually benefit from these cross-ventilation systems because within the building, it creates constant air renewals and thus reduces the internal temperature well.
- Stack Buoyancy or Ventilation: Into the lower level of buildings, this type of ventilation introduces cooler air from outside and as getting exposed to heat sources within the space, the air then becomes gradually warmer. This change in air temperature causes the new warm air to rise above and leave through openings that are present at the higher levels of the building. Keep in mind that, for tall structures with central atriums, this ventilation system is more effective and stack ventilation is also useful in situations where cross-ventilation failed to offer much result. The limitation of this ventilation could be, it is not much effective if the outside temperature is a bit higher than that of the inside.
- Chimney Effect: Commonly used in vertical buildings and its working might be like this, warm air gets under pressure by the cold air, and which forces it to go upwards. In this ventilation system, open areas in the center of project or towers helps circulate the same air throughout the indoor environment and finally leaving the structural body through the clerestory, zenithal openings, roof or the exhausts of the wind present in the same body or building.
2. Mechanical Ventilation
- Exhaust Ventilation: It works mainly by depressurizing a structure and the system uses exhaust fans to bring in more air through leaks in the building shell and intentional, passive vents; and by making a pressure difference in the inside environment which results in pulling more air in. The system works well in colder climates because in warmer climatic zones, the air outside is hotter and muggy, thus the system fails to offer you the best output. In order to install them in your home, these systems are easy to build and won’t break your bank much. All you need is a fan and some central exhaust pipes connected scientifically to draw more air in, and for the record, a better design could be, connecting the fans to the ducts from several rooms as a single operational body, which results in a combined and better output. You can also introduce passive vents to the system, they probably won’t work well for an optimal output but if the in or outside pressure difference is higher, then the passive vents are a plus.
- Supply Ventilation: It works opposite to the exhaust ventilation, because these systems are used to pressurize the structure, mainly by forcing the air outside into the interior of a building. But the air eventually leaks out through holes in the shell, bath and range fan ducts and also from intentional vents. Installation of these systems can be comparatively simple and not that expensive. Passive ventilations happens through adjustable window or wall vents present inside, but this system actively uses a duct system and an exhaust fan which introduces fresh air to the rooms where residents occupy the most. The ventilation system offers a better control of the air flow and works well in hot or mixed climate conditions.
- Balanced Ventilation: As the name suggests, this ventilation system is not designed to neither pressurize nor depressurize a structure, but it offers an approximately balanced approach by drawing in fresh outside air and exhaust polluted inside air. The operations happen mainly through two fans and two duct systems, and there are possible fresh air supply and exhaust vents installation could be done in every room. One of the main advantages for these systems are, they are apt for mostly all climate conditions around the world.
- Energy Ventilation: It is the way of minimizing the energy loss by maximizing the mechanical output through providing a controlled way of ventilation inside the home. There are two important energy recovery systems: Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs), both types consist of a heat exchanger and one or many fans to push or pull the air through the machine and control the flow. There are mini wall or window mounted or whole structural ventilation models are present with shared ductworks or duct systems. We will write more about ERV and HRV in the coming articles. So, keep us bookmarked and visit often.
3. Hybrid Ventilation
- It uses both passive and mechanical ventilations in one system but in advanced hybrid ventilations, they offer intelligent controls like the fine balance between quality of the indoor air, thermal comfort of the residents, and reduced electricity peak demand. By controlling fan options, according to the local climate control and minimizing fan energy during favorable outdoor climate parameters or conditions, the operations get energy efficient really quick.
- Adaptive Thermal Comfort (ATC): This system works well along with the adaptability of the occupants because those who feel in control of their indoor environment may tolerate a little or wider range of the indoor temperature. ATC is the idea based mainly on a resident’s control over their environment and connection to the outdoors as well. This connection allows the adaptability of occupants to a wider range and degree of thermal conditions than normal. Adaptive comfort of the occupant is much better, because these ventilation systems are more transparent, simple and responsive.
