Casals Ventilation Fans will talk about types of ventilation depending on the topics presented, but think about these questions first. Can you imagine a world without fresh air? What if you had to breathe in polluted air? It is very frustrating! Certainly impossible! In fact, living organisms cannot withstand these conditions.
By the study of Casals Ventilation Fans humans consume and breathe more than 12,000 liters of air every day. In a world where we spend more than 90% of our time in closed buildings. The importance of ventilation is more obvious.
But the first question is what is ventilation? How do you understand that the ventilation is working properly? If not, how can I improve it? What type of ventilation is in the building?
Ventilation
Ventilation works like the lungs of a building. It is the process of moving outside air into a building or room and spreading it into space. Fresh air dilutes the polluted air indoors. Some of the polluted air is replaced. The main purpose of ventilation is to provide healthy air for people to breathe in the facility.
Ventilation rate
The quantity of outside air that is supplied to the place. The ventilation rate is related to the quality of outdoor ventilation in a particular area. The building must meet ventilation standards. This is often different from residential and commercial buildings. The usual units of ventilation transmission are cubic feet per minute (CFM), liters per second (L/s), and cubic meters per hour (m3/h). Liters per second 3.6 cubic meters per hour. In addition, each CFM element has a volume of about 1.7 m³ / h. These units can be used interchangeably.
Air flow direction: All air flow direction.
By its name, the direction of airflow is the place where the air enters the room. You need to go from a clean place to a polluted world in a perfect world.
Airflow pattern: Airflow pattern or airflow distribution
This indicates that the air must be circulated so that it can be efficiently supplied to each area. In order to be successful, you need to communicate the pollutants that occur in the area. When considering these factors, the efficiency of the ventilation system can be evaluated in four areas.
Is the ventilation system sending exhaust from all over the room?
The Casals Ventilation Fans are other indexes as well. Let’s talk more about it, which will help you evaluate the performance of your system, but first let’s look at the types of ventilation systems.
Types of ventilation
Ventilation is generally divided into five categories: natural, mechanical, hybrid, and central and important conditioning (TAC). It doesn’t matter where you run the building or wherever you are. You should consider one of these five types of ventilation systems in a building. Natural ventilation or conventional ventilation systems rely on natural forces such as wind and thermal buoyancy. Three factors that affect natural ventilation and that drive winds out of the building through the opening of the building include climate and human behavior building design.
Building Designer
While designing buildings, designers should provide custom openings such as doors, windows, solar chimneys, wind towers, etc., if they function properly. Natural ventilation reduces energy consumption by 20-25%. You might think that when you talk about natural ventilation, you open the windows in the room, but it’s more complicated than you think. In certain places where there is more pollution on the outside than on the inside. Natural ventilation may work in the opposite direction. It not only ventilates the room, but also causes pollution. Exhaust can enter the building through the hatch. It puts our health at risk. This is due to the lack of much control while using natural ventilation. Therefore, in most cases it will be replaced by a mechanical one. However, HVAC Companies in Pakistan can find different types of ventilation systems.
