How to correctly install a fresh air exchange system

Before installing a fresh air exchange unit, it is essential to first read the installation and operation manual provided by the manufacturer to understand the structural features and key installation points of the fresh air exchange unit. The high-quality Kuaijing brand fresh air exchange unit produced by Xuri Air Conditioning Equipment Co., Ltd. achieves an energy exchange recovery rate of over 60%, significantly higher than the 29%-40% conversion rate of similar products. The products are widely used in factories in the food and chemical industries, and are also used in KTVs, internet cafes, gyms, coffee shops, banks, bars, and other business venues. The company has a team of first-line production skilled workers with high ideological and technical qualities, selected through rigorous processes. The produced fresh air exchange units boast high heat exchange rates, low noise, large air volume, sufficient head pressure, and long lifespan, making them popular with customers. The company enjoys an excellent corporate reputation, with products distributed throughout the country and exported to eleven countries worldwide. Before installing the fresh air exchange unit, carefully check if it is complete and undamaged, and whether all fasteners and bolts are loose or missing. Check the fan blades from the air outlet to see if they are deformed or damaged during transportation. If installing a ceiling-mounted fresh air exchange unit, first check if the floor slab's load-bearing capacity meets the requirements. For larger ceiling-mounted fresh air exchange units, determine the hoisting plan in advance. Generally, if the fresh air exchange unit is not heavy, the top of the hanging rod is connected to the floor slab using expansion bolts, and the bottom of the hanging rod is connected to the mounting hole using bolts with rubber vibration dampers. Carefully determine the size of the hanging rod radius to ensure safety. For high-volume ceiling-mounted fresh air exchange units, due to their heavier weight, it is necessary to adopt certain safety measures during installation. If installing a vertical fresh air exchange unit, the height of the base must meet the structural requirements, ensuring that the bottom of the embedded bolts has a sufficient concrete protective layer to reduce vibration.

　　The installation of the fresh air exchange unit should adopt appropriate vibration damping measures. Generally, vibration damping devices are already installed between the fan and the bottom frame of the fresh air exchange unit. For smaller standard fresh air exchange units, the hanging rod can be directly connected to the unit mounting hole using bolts and washers. If the fresh air exchange unit vibrates excessively during trial operation, vibration damping devices should be added. Either add rubber pads under the mounting hole to reduce vibration between the hanging rod and the fresh air exchange unit, or add vibration damping springs to the middle of the hanging rod. When connecting the air outlet of the fresh air exchange unit to the air duct, it is necessary to use a canvas flexible hose. After the fresh air exchange unit is installed, check the airtightness around the air outlet. If there are gaps, seal them with glass glue. When choosing the installation location of the air outlet, note that there should not be any large obstacles within 2.5-3 meters in front of the air outlet. After the installation of the fresh air exchange unit, check whether there are any remaining tools or debris inside. After installation, the fresh air exchange unit should be adjusted to ensure it is level. Then check if the fan is running balanced and in the correct direction. Use your hand or a lever to move the fan blades to check for tightness or rubbing, and for any obstacles hindering rotation. Only after no abnormalities are found can a trial run be conducted. During the trial run of the fresh air exchange unit, if there is vibration, unusual buzzing sounds from the motor, or other abnormalities, stop the machine and check. Repair before restarting and using. Correct installation methods are crucial. Fresh air exchange unit installation work must be meticulous and careful to ensure personal safety and that the fresh air exchange unit can operate stably and normally for a long time after installation.
