Combine functional sections according to project working conditions to provide air treatment matching for industrial plants and clean air systems.
Aili industrial combined air conditioning box, also known as combined air handling unit and combined air conditioning unit, is a device that combines different air treatment functional sections according to the design process. Functions such as filtration, cooling, heating, humidification, mixing and air supply can be configured according to project needs for centralized processing of fresh air, return air or mixed air.
Product selection is based on the target air volume, external static pressure, air inlet and outlet conditions, and on-site installation conditions. At the same time, filter resistance, functional section layout, control interfaces, and maintenance space are taken into consideration to facilitate matching with project air ducts, cold and heat sources, and terminal air supply equipment.
→ Functional segments can be combined as needed → Box size supports customization
→ Matching of fan and filtration configuration → Taking into account installation and maintenance conditions
The air treatment processes vary from project to project. The combined air-conditioning box can determine the type, sequence and size of functional sections based on the fresh air ratio, temperature and humidity requirements, filtration requirements and installation conditions.

Each functional segment is optional, and the actual configuration is subject to the project selection plan.
The combination plan can be determined around air supply volume, air treatment process and equipment layout, and is suitable for industrial air treatment and clean room supporting projects of different sizes.
When selecting the model, check the air volume, initial resistance of the filter and resistance changes during use, as well as the resistance generated by the coil, functional sections and external air ducts, and reasonably determine the fan working point and speed regulation method.
According to the size of the computer room, transportation channels, equipment foundation and air duct direction, determine the box shape, segmentation form, air inlet and outlet location and maintenance side to reduce the problem of interface mismatch after the equipment arrives at the site.
Combined with the needs of filter replacement, fan maintenance, coil cleaning and drainage inspection, determine the location of the access door and operating space to facilitate subsequent maintenance.
Functions such as start-stop, speed adjustment, temperature and humidity adjustment, filter pressure difference prompts, and equipment linkage can be communicated according to project requirements. The specific control configuration and communication interface will be confirmed in the planning stage.

When used in clean rooms, the overall design should be combined with terminal filtration, air flow organization, enclosure structure and operation management. The cleanliness level needs to be confirmed through system debugging and testing.
Aili Industry has R&D and manufacturing capabilities in motors, fans, control systems, sheet metal processing, air filters and complete machine assembly. It can carry out collaborative selection around the air supply, filtration, structure and control requirements of combined air-conditioning boxes.
During project communication, the fan working point, filter resistance, box interface and control method can be checked in the same plan, and the standard configuration or non-standard plan can be determined based on the site conditions. When it needs to be matched with FFU, HEPA/ULPA filters and high-efficiency air supply outlets, the interface and operating conditions of the relevant equipment can also be confirmed simultaneously.

To facilitate determination of product configuration, it is recommended that the following information be provided:
Usage scenarios: project industry, service area and operation period.
Air parameters: total supply air volume, fresh air volume, return air volume and external static pressure.
Temperature and humidity conditions: outdoor design conditions, return air status and target air supply status.
Hot and cold source conditions: cold water, hot water, steam or other available energy conditions.
Filtration requirements: filtration level, installation location and maintenance requirements.
Site conditions: available space, transportation channels, air inlet and outlet locations and maintenance directions.
Control requirements: start and stop, speed regulation, sensors, alarms and communication interfaces.
Existing equipment drawings or project parameter sheets can be submitted directly for further verification of functional segments and installation interfaces.
In many engineering and product literature, both are used to describe similar equipment. 'Air conditioning box' is a common name, and 'combined air handling unit' emphasizes that the equipment is composed of different functional sections. The actual configuration and parameters should be checked when selecting.
Aili Industrial can be designed according to fresh air conditions, and can also handle return air or fresh return air mixed air. The cooling and heating loads, filtration configurations and functional section sizes corresponding to different air conditions are different and need to be calculated separately.
The products on this page are configured according to the cold and heat source conditions of the project. When using cold water coils, an external cold water system is required; when direct expansion refrigeration is required, a direct expansion unit solution should be confirmed separately. The name 'combined air conditioning box' alone cannot determine whether it has its own refrigeration system.
The clean room effect needs to be achieved by the air handling unit, terminal filtration equipment, air flow organization and building conditions. The system should be designed according to the target cleanliness level and confirmed through debugging and testing.
It can be customized based on functional sections, air volume, installation space and air duct direction. When determining the overall dimensions, space must be reserved for fan maintenance, filter replacement and coil maintenance.
The combined air-conditioning box needs to match the project air volume, cold and heat sources, air duct system and control requirements. Clarifying the air treatment objectives, external static pressure, installation dimensions and maintenance conditions in advance will help reduce subsequent interface adjustments and repeated selections.
