Ventilation systems ensure that any place where it is located is a healthier and cleaner place. It has an important place in many fields. It prevents the spread of bad odor in the environment in a restaurant, the inhalation of toxic gas in a factory, and the decrease in working efficiency in an office or school. It is absolutely necessary to ventilate no matter what material is worked in a factory or any work area. However, ventilation provides very limited protection against dangerous gases, steam, smoke and dust. For an effective ventilation system, it provides a clean breath that is not contaminated with chemicals for employees. Ventilation systems differ according to the area of use, and the ventilation system used in a restaurant is different from the system used in a carpenter. This difference changes according to the weather conditions. While dust and sawdust pollute the air in a carpentry, the problem in a restaurant is the spread of odour. There are three types of ventilation to clean the odor-condensed air in the environment. These are local, central and hood ventilation systems. The local ventilation system is used in small offices and offices. There is no need for ductwork. It works with 220 volts, simple electric motor and wall-mounted aspirators are used. It is the easiest ventilation system to clean and maintain. The central ventilation system, on the other hand, is used in places with heavy crowds such as shopping malls and museums. Unlike local ventilation systems, central ventilation systems require duct installation and cell aspirators are generally used. It has a stronger and larger structure as it works throughout the day. Care must be taken during installation as maintenance and repair works are more difficult and troublesome than other ventilation systems.
Hood ventilation systems are basically known ventilation systems among the public. The hoods used in the kitchens of the restaurants allow the gas released by the burning stoves to be thrown out. The most important reason for these systems is not to be protected from situations such as gas leaks, but to ensure that the used, that is, burned, gases are discharged from the environment. There are three methods that can be used to ventilate a building: natural, mechanical and hybrid ventilation. Natural forces direct outside air through purpose-built openings, including windows, doors, solar chimneys, wind towers and drip fans. This natural ventilation of buildings depends on climate, building design and human behavior. Fans are the source of mechanical ventilation. Fans can be mounted directly on windows or walls, or mounted in air ducts to supply or extract air from a room. It also gives more control over how much outside air is added and the source of the air. Mechanical ventilation prevents the accumulation of odors, excessive moisture and pollutants in your living and working areas. They can be removed from important areas of your home in your kitchen and living room, but also from common areas such as restaurant kitchens, gyms, locker rooms and toilets. For business, excessive humidity and odor can be costly and cause worse problems such as mold and damage to furniture and equipment.
In summary, ventilation systems are used to change the air of a closed environment and to create a healthier and more spacious living space. It is of great importance to many businesses.
How to Ventilation?
If there is no ventilation in common areas and indoor areas, it becomes impossible to live in these areas. Professional ventilation systems are used for these situations. The amount of air required in an environment varies according to the volume of the space, the way it is used, and the number of people who are constantly present. For this reason, the most ideal project for ventilation is prepared by considering every possibility. Ventilation options, which will be determined according to the ventilation requirement, are always made with the best in mind. Because the ventilation needs of a gym and a restaurant will not be the same.
What are Ventilation Systems?
Ventilation systems are used in many different areas. Therefore, there are multiple types and they are as follows;
Kitchen exhaust systems
Heat recovery systems
Pool dehumidification systems
dental polyclinic ventilation system
Restaurant ventilation systems
cafe ventilation systems
Stainless steel chimney systems
Office ventilation systems
Fresh ventilation systems
Parking lot ventilation systems
Air handling units
What are the advantages of ventilation systems?
It is possible to list the advantages of ventilation systems as follows;
Undesirable pollutants such as dust, steam and smoke inside are absorbed by ventilation systems.
The quality of life and production increases by giving fresh air inside.
Fresh air can be supplied to the indoor areas continuously.
Situations such as fire and explosion are eliminated.
Bad odors are easily blocked.
How Ventilation Should Be in Workplaces?
There is no legal regulation on how ventilation will be in workplaces. However, it is ensured that sufficient clean air is available to the employees in the closed workplaces as stated below in Articles 15-18 of the Regulation on Workplace Buildings and Extensions. In determining the sufficient air volume, the working method, the number of employees and the work done by the employees are taken into account. It is ensured that wastes and residues that can harm the health of the employees by polluting the working environment air are immediately thrown out. A mechanical (forced) ventilation system is installed separately from the general ventilation system in a form and quality that will remove suffocating, poisonous or irritating gas, dust, mist, smoke and bad odors from the environment. When the mechanical ventilation system is used, it is ensured that the system is always operational. If the ventilation system does not work and is dangerous in terms of occupational health and safety, a control system is established to notify the malfunction. The maintenance and repairs of mechanical and general ventilation systems and the use and replacement of appropriate filters are made annually by authorized persons. In passive (artificial) ventilation systems, it is ensured that the air flow does not disturb the employees, does not adversely affect the physical and psychological conditions of the employees, and does not create a sudden and high temperature difference. Occupational health and safety measures should be taken into account with its recipe. Occupational health and safety in mining workplaces in Article 8 and its sub-clauses, in construction works, in Annex 4-A Article 35, 36, 37, 38 Annex 4-B 3.72-a, health and safety in working with chemical substances As stated in Article 7-2 of the regulation on the precautions, the importance of ventilation has a priority in terms of employee health and safety.
The 5 items required for the proper operation of Industrial Ventilation and Filtration systems are:
- Review of all documents including minimum flue and pipe velocities as well as fire and explosion protection
- Review of fan and motor operating requirements
- Ensure all compressed air, water and controller are working and complying with specifications
- Checking for glitches that may be more difficult to fix in the future
- The system to be installed should not create additional risks (such as noise) for employees due to problems arising from selection errors or installation errors.
There are points to consider when installing ventilation systems. At this stage, support should be obtained from a professional company and the whole process should be completed with expertise. Air conditioners are installed in smaller buildings such as a house or office, and a suitable area is explored for this. If professional support is taken about which rooms it should be used and what its power should be, the efficiency it will provide will be much more. For larger structures and businesses where ventilation systems are used, much more detailed and extensive operations are required. In order to maximize the performance to be obtained from the ventilation systems, a drawing should be made and the most accurate positioning should be determined.
