2. Implementation Steps
-
Site Assessment: Analyze the drying line’s exhaust gas characteristics, including temperature (typically 100–200°C), flow rate (e.g., 5,000–20,000 m³/h), and composition (e.g., presence of VOCs or coating residues).
-
Heat Exchanger Selection: Choose a BXB model with appropriate heat transfer capacity and material (e.g., stainless steel for corrosion resistance) based on exhaust conditions.
-
Installation:
-
Integrate the BXB heat exchanger into the exhaust duct downstream of the drying oven.
-
Connect the fresh air intake to the heat exchanger’s cold side, ensuring proper airflow alignment.

A fresh air ventilation system for a factory is a specialized air handling solution designed to continuously supply filtered outdoor air into the factory space while exhausting polluted indoor air. This helps maintain air quality, protect workers' health, and support compliance with environmental and safety regulations.
Key Purposes of a Factory Fresh Air Ventilation System
1. Improve Indoor Air Quality
Factories often produce dust, fumes, chemical vapors, and heat during operations. A fresh air system helps dilute and remove these pollutants by bringing in clean air and expelling contaminated air.
2. Ensure Worker Health and Safety
Long-term exposure to poor air quality can lead to respiratory issues and lower productivity. Proper ventilation reduces risks associated with toxic gases, high CO₂ levels, and airborne particles.
3. Regulate Temperature and Humidity
Although the primary function is ventilation, some systems incorporate heat recovery or basic temperature control to help maintain a more stable indoor environment, especially in enclosed workshops.
4. Comply with Occupational and Environmental Standards
Industrial facilities are often subject to air quality and safety regulations. A fresh air system ensures compliance with standards such as OSHA, ISO, or local environmental protection codes.
5. Reduce Equipment Damage and Fire Risk
By controlling dust, fumes, and excess humidity, ventilation systems help extend the life of machinery and reduce the risk of explosions or fire hazards in areas where volatile substances are handled.
Typical Features of a Factory Fresh Air System
-
High-capacity air intake and exhaust fans
-
Multi-layer filtration (coarse, fine, HEPA, or activated carbon)
-
Ducted or ductless design depending on the factory layout
-
Optional heat recovery units to save energy
-
Intelligent control systems for airflow, pressure, and CO₂ monitoring
-
Weather-resistant outdoor air intake units
Applications
Fresh air ventilation systems are commonly used in:
-
Electronics assembly workshops
-
Chemical processing plants

Conclusion
A well-designed fresh air ventilation system is essential for any factory that values employee well-being, process stability, and long-term sustainability. It not only ensures clean and breathable air but also supports safe, efficient, and compliant industrial operations.
The fresh air system and central air conditioning are both common air handling systems in modern buildings. While they are both related to indoor air, their functions, principles, and purposes are completely different. Below is a detailed comparison:
1. Different Functional Focus
The primary function of a fresh air system is to introduce fresh outdoor air and expel stale indoor air, thereby improving air quality.
The main function of a central air conditioning system is to regulate indoor temperature, providing cooling or heating to enhance comfort.
2. Different Working Principles
A fresh air system uses supply and exhaust fans to bring in outdoor air and remove indoor air. Some systems also include heat recovery units to reduce energy loss.
A central air conditioning system uses compressors and fan coil units to cool or heat the indoor air in a closed-loop circulation without exchanging air with the outdoors.
3. Different Air Sources
Fresh air systems process outdoor air, which is filtered before being delivered indoors.
Central air conditioning systems process indoor air, recirculating it without introducing fresh air.
4. Impact on Health and Energy Efficiency
Fresh air systems help increase oxygen levels, reduce bacteria and odors, and are better for long-term health, especially in enclosed spaces.
Central air conditioning, if used alone for extended periods, can cause stuffy air and promote bacterial growth due to lack of ventilation, which may negatively affect health.
5. Can They Replace Each Other?
Fresh air systems cannot regulate temperature, so they cannot replace air conditioning.
Central air conditioning systems do not provide fresh air, so they cannot replace fresh air systems. Their functions are complementary and not interchangeable.
Conclusion
In simple terms: Central air conditioning adjusts temperature; fresh air systems handle ventilation. Each plays a different but essential role. To achieve both comfort and healthy indoor air, it is recommended to use both systems together.
