What are the correct standards for factory ventilation and cooling?

Currently, factory ventilation and cooling are trusted and chosen by many manufacturing enterprises from small to large scale. Because the ventilation and cooling systems ensure the freshness of the working environment of employees, thereby ensuring their health and besides, ensuring progress and productivity through the quality of products made by the factory. However, not all businesses know the correct standards for factory ventilation and cooling? A qualified ventilation system must be designed appropriately and ensure the criteria desired by the user.

Hereafter, Sao Viet Air Duct Please share some basic knowledge in the construction and installation of this system, the most popular and effective negative pressure cooling system today.

1. Ventilation and cooling standards for factories according to regulations:

Factory ventilation standards are mandatory regulations or requirements of the state (or relevant parties) to ensure the quality and safety of each project. To achieve good efficiency and ensure safety, factories need to strictly comply with the following standards from design to construction and operation. Each factory ventilation system before installation will need to meet the following standards:

TCVN 5687:2010: Ventilation air conditioning design standards.

Purpose: provide air calculation parameters, air cleanliness inside and outside the factory; Air flow calculation; Installation location of equipment in the system and power requirements.

TCXD 232:1999: Standards for ventilation, air conditioning and refrigeration systems - Manufacturing, installation and acceptance

Purpose: Synthesize the manufacturing specifications of air ducts, ventilation system accessories (air vents, valves, hoods, etc.); manufacture air handling components (heat and humidity treatment chambers, air filters, silencers, dust collectors, etc.); how to install air ducts, etc. How to test the system and Sample acceptance report.

TCVN 4088:1985: Standard on climatic data for building design

Purpose: Provide specific data on climate at each location nationwide. Based on that, architects can easily calculate the flow and number of ventilation fans needed for factories in that area.

TCVN 4605:1988: Design standards for thermal engineering - partition structures

Purpose: Provide calculation formulas and standard parameters when designing insulation for partition structures in buildings with specified microclimate conditions.

ASHRAE 2007 (USA): Air Conditioning Standards

Purpose: Provide the lowest basic standards for factors such as air filtration, factory cooling, air conditioning, etc. However, in each country when applying this standard, architects need to adjust or supplement accordingly: environmental conditions - weather, number of workers in the factory, surrounding terrain, etc.

SMACNA (USA): Standards for manufacturing and construction of duct systems

Purpose: To provide instructions on how to connect standard air ducts, ensuring technical standards. At the same time, to provide regulations on the size of accessories that come with air ducts, limiting the occurrence of risks and damage to people and property.

BS EN 12101 (UK): Standard for stair pressurisation systems

Purpose: Provide calculation methods as well as certain standards and regulations on calculating the amount of smoke that needs to be removed to ensure worker safety, prevent the spread of fire, and protect business assets in the event of a fire.

CP13 (Singapore): Standards for ventilation - air conditioning and fresh air supply for factories

Purpose: Provide a table of standard fresh air flow and frequency of fresh air needed to be supplied to the factory in one hour to help businesses quickly choose the most suitable fan type. Thereby creating the best working conditions for workers.

2. What else should be noted when building a factory ventilation system?

For projects such as factories, workshops, etc., the construction of ventilation pipes is one of the mandatory rules when constructing. When installing a ventilation system, it helps ensure the circulation and rotation of air, helping to provide a source of clean air in that space. Below are some notes when constructing.

Installation location, number of fans installed and capacity

For the ventilation fan to be effective, the location of the ventilation fan is very important. When installing, avoid placing the fan at head height, in places with many people passing by because it will affect human health when the air suction pressure is high. You should install it at a position higher than head height, where there are few people passing by to create an effective working space.

Air ducts are suitable for the climate and temperature conditions where the factory is located.

To choose the right ventilation system, you should consider the climate and temperature conditions in the factory. If the factory is located in a cool place, you should choose an industrial exhaust fan. If the factory is located in a place with high temperatures, you should use a negative pressure ventilation and cooling system to help regulate the temperature inside the building.

Choose a reputable manufacturer and contractor

The installation of ventilation systems for factories must be carried out by a team of professional workers. It is necessary to plan in detail and specifically from the location design, choosing the type of system or installation cost...
