Improve air quality: Fresh air circulation system transport air or gas through the duct system, effectively exhaust dirty air and introduce fresh air, thereby improving indoor air quality and improving people's living and working efficiency.
Improve environmental comfort: In factory workshops, office buildings, shopping malls, schools, hospitals and other places, fresh air circulation system can provide continuous fresh air, exhaust harmful gases, and create a healthier and more comfortable environment.
High efficiency and energy saving: Fresh air circulation system design focuses on efficiency and energy saving. It adopts advanced blade technology and materials, which can provide strong wind output while reducing energy consumption, greatly reducing operating costs.
Low noise operation: By optimizing the fan structure design, the noise generated by the fresh air circulation system during operation is extremely low, which is particularly suitable for places that need to maintain a quiet environment, such as school classrooms, hospital wards, etc.
Flexible installation: The fresh air circulation system is small in size and has a variety of installation methods. It can be customized according to different space requirements. It is suitable for new projects and renovation of old buildings.
Various application scenarios: Fresh air circulation system is widely used in industrial production environments (such as chemical plants, pharmaceutical factories), commercial buildings (such as large shopping malls, supermarkets) and living environments (such as residential areas) to ensure air circulation and freshness.
Application of Fresh Air Circulation System
Industrial production environment
In industrial environments such as chemical plants and pharmaceutical plants, fresh air circulation systems are used to discharge harmful gases to ensure the health and safety of workers, while providing sufficient fresh air to ensure air circulation during the production process.
01
Commercial buildings
Large shopping malls, supermarkets and other commercial buildings are densely populated and have high requirements for air quality. Fresh air circulation system can circulate air quickly, keep the room fresh, and enhance the customer shopping experience.
02
Residential environment
In residential areas, fresh air circulation system can be used as part of the home fresh air system to continuously introduce fresh air from the outside and exhaust dirty air from the inside to create a healthier and more comfortable living environment.
03
Transportation facilities
Public transportation hubs such as airports, railway stations, and subway platforms require good ventilation and smoke exhaust systems. Fresh air circulation systems are suitable for ventilation needs in long distances or complex spaces, such as tunnels, subway platforms, and other places.
04
Special environments
Fresh air circulation systems are also widely used in spaces with strict requirements on air cleanliness, such as hospital operating rooms and laboratories. Fresh air circulation system can provide fresh air for the room and maintain air circulation in these environments.
05
Fan: Fresh air circulation system usually adopts centrifugal multi-blade fan or cross-flow fan. The impeller diameter of the fan is generally not more than 150mm, and the static pressure is maintained below 100Pa. In order to ensure fire prevention and thermal deformation safety, metal impellers are currently mostly used, made of galvanized steel plate, aluminum plate or ABS engineering plastic.
Fan motor: The motor usually adopts capacitor motor, and its speed regulation function can be achieved by changing the input voltage. With the increase of energy-saving demand, DC brushless motor has gradually become the mainstream in recent years. This type of motor has the characteristics of small size, light weight, low temperature rise and high energy efficiency.
Coil
The coil is composed of copper tube and corrugated or windowed aluminum sheet. The outer diameter of the copper tube is 10mm, the wall thickness is 5mm, and the thickness and sheet spacing of the aluminum sheet are 152mm and 23mm respectively. Through the expansion process, the copper tube is ensured to be in close contact with the aluminum sheet to optimize the thermal conductivity. The number of rows of coils is usually two.
Air filter
The filter is made of coarse-pored foam plastic, fiber fabric or nylon braid, which is used to filter and purify the air entering the system.
Regulator
The general model adjusts the air volume through a three-speed variable speed switch (high, medium and low), while the model equipped with a brushless DC motor achieves continuous speed regulation through an AC-DC converter.
Tips for Using Fresh Air Circulation System
Installation location selection: Before installation, you need to carefully select a suitable installation location. It should be placed in a place that can provide sufficient space to ensure good air circulation and convenience for maintenance. At the same time, it should be kept away from flammable items and other objects that may threaten its safe operation.
Pipeline design and installation: During installation, the diameter and length of the pipeline should be selected according to the specifications and requirements to ensure smooth airflow. The bends and corners of the pipeline should be minimized to reduce the resistance of the airflow. Make sure that the pipeline is firmly connected and there is no air leakage.
Power connection and protection: When connecting the power supply, make sure that the voltage and current match the requirements of the equipment, use the correct cable and plug, and ensure that the power connection is firm and reliable. In order to protect electrical equipment, necessary protection devices such as overload protectors and short-circuit protectors should be installed.
Pre-operation inspection: Before starting, check whether the impeller and bearings are operating normally, and whether there is any abnormal sound or overheating. Check whether the safety protection device is intact and make sure there are no debris and obstacles around.
Correct operation: Follow the operation manual and safety regulations for operation, follow the use restrictions and requirements of the equipment, and do not exceed the rated working parameters. During the work process, check the operating status regularly, pay attention to the occurrence of abnormal conditions, and take timely measures to deal with them.
Regular maintenance: Clean the impeller and casing regularly to ensure smooth airflow. Check and lubricate the bearings regularly to reduce wear and friction. Check the electrical system and safety devices regularly to ensure their normal operation.
Efficient and energy-saving use: By adjusting the air pressure or air volume of the duct fan to meet production needs, the energy-saving solution of variable frequency motor speed adjustment can maximize energy savings. Choosing a suitable adjustment method can maintain the energy-saving effect of the duct fan under the premise of equal effect.
