The multi-fan linkage system of a humidification and fresh air integrated machine (HUAM) requires coordinated control to achieve a dynamic balance between air pressure and humidification efficiency. This requires optimizing the closed-loop logic of airflow organization, sensor feedback, and actuator response. When multiple fans operate simultaneously, the uniformity of air pressure distribution directly impacts the mist dispersion efficiency of the humidification module. Excessively high air pressure in a particular area can cause mist to disperse quickly, preventing adequate evaporation. Conversely, excessively low air pressure can cause mist to accumulate in a certain area, leading to condensation or uneven humidification. Therefore, the system utilizes variable-frequency fans to adjust speed and duct pressure sensors to monitor the air pressure in each branch in real time to ensure that airflow velocity matches humidification output.
Balancing humidification efficiency and air pressure relies on accurate feedback from humidity sensors. When ambient humidity falls below the set point, the system prioritizes increasing the output power of the humidification module and simultaneously adjusts the air supply direction through the coordinated multi-fan system to ensure that humidified air covers the target area. For example, during dry seasons, a humidification and fresh air integrated machine may activate a bidirectional flow fan, drawing dry outdoor air through the humidification module before delivering it to the indoor space via a high-pressure blower. The return air fan, meanwhile, operates at a lower speed to prevent excessive extraction and humidity loss. This differentiated air pressure control ensures humidification efficiency while reducing energy loss.
Duct design in multi-fan linkage is crucial for achieving optimal balancing results. A rational duct layout reduces airflow resistance and prevents pressure imbalances caused by excessive localized pressure drop. Humidification and fresh air integrated machines typically utilize a tapered duct structure with guide vanes to optimize airflow distribution and evenly disperse mist within the duct. Furthermore, the duct material selection must also consider moisture and corrosion resistance to prevent condensation or scale accumulation that can affect air pressure stability after long-term use.
Actuator response speed is a key factor in balancing air pressure and humidification efficiency. Electric dampers, variable-frequency fans, and humidification solenoid valves require millisecond-level synchronized control to ensure rapid adjustment to humidity or air pressure fluctuations. For example, when a sudden drop in humidity is detected in a specific area, the system must immediately increase the speed of the supply fan in that area, simultaneously increase the water spray volume of the humidification module, and adjust the air valve opening within 0.5 seconds to prevent humidification delays or overloads.
Controlling the mist particle size in the humidification module directly impacts evaporation efficiency and wind pressure loss. Excessively coarse mist particles tend to settle due to gravity, resulting in uneven humidification; while excessively fine mist may be carried away by the high-speed airflow, preventing sufficient evaporation. The humidification and fresh air integrated machine uses high-pressure micro-mist or ultrasonic atomization technology to control the mist particle size within the 5-15 micron range, ensuring rapid evaporation while minimizing air pressure obstruction. Furthermore, the linkage logic between the humidification module and the fan must be dynamically adjusted based on ambient temperature to prevent mist from freezing and blocking the air duct in low-temperature environments.
The redundant design of the multi-fan linkage system improves balance and reliability. By configuring backup fans and independent control modules, the system automatically switches to the backup unit and redistributes air pressure if a fan fails, ensuring humidification efficiency remains unaffected. Furthermore, a regular self-check function monitors potential issues such as fan bearing wear and damper sticking, providing early warning to prevent humidification anomalies caused by air pressure imbalance.
Humidity level and damper opening. For example, during the rainy season, the system may reduce humidification module power while accelerating indoor moisture removal through the exhaust fan. In winter, the system reverses this operation to maintain a comfortable humidity level. This intelligent balancing mechanism enables the integrated humidification and fresh air machine to operate efficiently even in complex environments.
