Ventilation system construction in an office helps businesses maintain fresh air, improve work performance, and reduce energy costs. How to design a ventilation system that is effective yet economical? Learn now about the suitable ventilation system construction solution for offices with the article below from Co-IDB.
What is Ventilation System Construction?
A ventilation system is an essential solution for adjusting and controlling airflow in enclosed spaces like offices, factories, hospitals, and schools. The main goal of this system is to maintain fresh air, regulate humidity, minimize noise, and create a safe, comfortable working environment for users.
A ventilation duct system includes main components such as air ducts, fans, control valves, air compressors, vacuum cleaners, air purifiers, air conditioners, along with flow and pressure sensors. Based on specific needs and technical requirements, ventilation systems can be designed diversely, including types like axial ventilation, directional ventilation, and zonal directional ventilation.
Why is Ventilation System Construction Important?
Similar to fire protection system construction projects, the construction of ventilation systems in office buildings, apartments, and supermarkets is indispensable today. This system brings many practical benefits, including:
-
Ensuring the air in the building is always fresh and unpolluted.
-
Removing smoke, dust, and harmful substances generated from daily activities and production.
-
Controlling temperature and humidity, creating a comfortable environment for users.
-
Supplying oxygen and removing $CO_2$, odors, and harmful bacteria.
-
Preventing stagnant air circulation by continuously drawing air from outside and pushing exhaust air out.
-
Creating an airy workspace, avoiding a stuffy and suffocating feeling.
-
Minimizing respiratory issues caused by poor air quality, contributing to user health protection.
Especially for buildings with basements or production workshops, such as projects like The Sun Avenue, Saigon Centre, etc., the design and construction of the ventilation system become even more important. The ventilation system helps improve air quality and protects products and goods, ensuring they are not damaged during storage.
Classification of Ventilation System Construction Methods
Classification by Structural Factors
Natural Ventilation System
This system is designed to utilize natural factors to circulate air in the office space. By using roof exhaust fans, roof-mounted ventilation ducts, along with air vents, windows, or office entrance doors, the natural ventilation system helps the air in the building circulate without relying on mechanical equipment. This circulation is entirely based on physical phenomena such as wind pressure and air diffusion.
Mechanical Ventilation System
Unlike the natural system, the mechanical ventilation system uses fans, machinery, and motors to create airflow into and out of the building. This system has the ability to adjust suction and blowing force, as well as increase or decrease pressure to suit the office space, thereby providing fresh and comfortable air for users.
Hybrid Ventilation System
The hybrid ventilation system combines both natural and mechanical systems. Ventilation equipment can operate independently or in coordination depending on the time of day or season. Since natural factors are not always stable, the mechanical system will assist the natural system when necessary, ensuring optimal ventilation efficiency for the office space.
Classification by Method Factor
Supply Ventilation (Blowing Type)
This method uses a fan system to blow clean air into the office space, helping to remove dust, $CO_2$, and other exhaust gases generated during daily activities.
In addition to being effective in improving air quality, the supply method is also cost-effective because it does not require modern equipment, utilizing fresh natural air sources.
Exhaust Ventilation (Suction Type)
This method is particularly suitable for spaces like kitchen areas, where employee lunch cooking activities take place, easily accumulating unpleasant odors. Exhaust ventilation helps remove odors directly from the source, preventing them from spreading to other areas in the office.
Although it has clear advantages, this method suffers from the drawback of low air circulation capability in the room, meaning the air in the room is not refreshed frequently.
Combined Ventilation
This is the most optimal method for ventilation systems in a building, combining both blowing clean air in and extracting exhaust air out. Thanks to this approach, the office space is always ensured to be airy and cool with fresh air.
However, the combined method requires higher investment than other methods but offers superior effectiveness in maintaining air quality.
Office HVAC Ventilation System Construction Process
The office ventilation system construction process is carried out through 09 steps to ensure project effectiveness and quality:
-
Information Reception: First, the team of experts will receive requirements from the customer and conduct a survey of the construction area to understand the actual conditions.
-
System Design: Based on the information gathered, the ventilation system will be designed to suit the building’s characteristics and construction cost estimation will be prepared.
-
Send Drawings and Quotation: The design drawing and cost estimation table will be sent to the customer. At this step, the information on the drawing and costs will be agreed upon.
-
Detailed Drawing Preparation: After customer confirmation, a detailed drawing will be prepared and the installation progress will be confirmed.
-
Contract Signing: Proceed with contract signing and preparation of necessary materials for the construction process.
-
Ventilation System Installation: Proceed with the installation of the building’s ventilation system, ensuring compliance with the requirements in the design drawing.
-
Measurement and Calibration: After installation is complete, the team will conduct measurement and calibration for project acceptance.
-
Acceptance and Repair: Project acceptance and receiving repair requests from the customer (if any).
-
Final Acceptance: Finally, the project will undergo final acceptance, accompanied by warranty and contract liquidation after the warranty period expires.
