AHU in the purification industry primarily serves production processes, then secondary serving for people. The industrial purification industry has special standards and specifications for various parameters of air-conditioned rooms, and generally has high accuracy requirements for parameters such as temperature, humidity, pressure, air volume, and cleanliness. The requirements for AHU type selection, design, and processing are relatively high. AHU generally has the characteristics of large air volume, high unit pressure, high filtration level, and relatively complex control.
Combination section style commonly used in industrial purification applications:
Mixing + primary efficiency filtration + surface cooling + heating + humidification + fan + flow equalization + medium efficiency filtration + air supply section.
This combination is the most commonly seen style. The mixing section is usually equipped with an air valve to adjust the proportion of fresh and return air. The primary filtration section is usually equipped with G3 and G4 plate filters, and some customers may require the use of bag filters.
