Features and Application Scope

The KD(X) series ceiling-mounted air handling units are terminal suspended air handling units for central air conditioning systems. They can filter, cool, dehumidify, heat, perform enthalpy humidification, and introduce fresh air to the air. Suitable for delivering treated air to distant locations via air ducts, they are particularly ideal for small commercial and industrial building air conditioning projects.

This series includes 13 models with 39 specifications, featuring an air volume ranging from 1500 m³/h to 15000 m³/h and a cooling capacity from 8.4 KW to 324.8 KW. The units are available in milky white or blue, with built-in nylon filters. The heat exchanger uses φ16 copper tubes with high-efficiency aluminum fins, and its heat exchange efficiency is significantly enhanced after mechanical tube expansion.

Note:

1. The weights listed in the table represent the net weight of the unit itself. The operating weight is 20% higher than this.

2. Standard cooling condition: Inlet air dry bulb temperature 27℃, wet bulb temperature 19.5℃, inlet water temperature 7℃.

3. Fresh air cooling condition: Inlet air dry bulb temperature 35℃, wet bulb temperature 28℃, inlet water temperature 7℃.

4. Standard heating condition: Inlet air dry bulb temperature 150℃, inlet water temperature 60℃.

5. Fresh air heating condition; Inlet air dry bulb temperature 7℃.

6. At 35℃/28℃ in fresh air condition, the total pressure outside the unit is 25Pa lower than that of the standard condition (27℃/19.5℃).

7. The total pressure outside the unit in the table is for reference only. During actual production, it can be designed according to the user's requirements. However, the power of the unit may not be consistent with the values in the table.

8. This series of units are equipped with a variable frequency control cabinet, allowing for variable air volume usage, which is energy-saving and efficient.

Product Details

01 External Rotor Centrifugal Fan

Equipped with an external rotor centrifugal fan, the unit operates stably with low noise and a long service life, maintaining strong power at all times to ensure efficient and continuous air supply for the fresh air system.

02 Hydrophilic Aluminum Foil Surface Cooler

Equipped with a hydrophilic aluminum foil surface cooler, it has good corrosion resistance and prevents mold growth, improving cooling and heating efficiency and avoiding clogging by water droplets and dust.

03 Primary Filter Screen

The unit is equipped with a washable primary filter screen, which can effectively filter out large-particle pollutants such as dust and impurities, protecting the internal components of the unit and ensuring the quality of fresh air.

Application Environment

Operation And Maintenance Of The Unit

1.The cold and hot media of the unit should be clean softened water, and the working pressure should not exceed 1.6 Mpa.

2.During normal operation of the unit, the temperature rise of the fan bearings should not exceed 40℃.

3.The outlet pipe of the unit is equipped with an exhaust valve. Before the first operation and during the cold and hot medium conversion, the exhaust valve should be opened to discharge the air in the heat exchanger and pipeline to avoid affecting the heat exchange effect. In summer, the supply water temperature of the unit should not be lower than 50℃, and in winter, the supply hot water temperature should not be higher than 70℃.
