Note:
■ The preceding parameters apply to the standard model. EK provides customized design to meet special requirements.
■ Nominal air return cooling condition: 27°C (dry bulb)/19.5°C (wet bulb). Nominal fresh air cooling condition: 34°C (dry bulb)/28°C (wet bulb). Nominal cooling water inlet/outlet temperature: inlet
7°C; outlet 12°C.
■ Nominal air return heating condition: 21°C (dry bulb). Nominal fresh air heating condition: 0°C (dry bulb). Nominal heating water inlet/outlet temperature: inlet 60°C; outlet 50°C.
■ The unit weight listed in the table is net weight. The operating weight increases by about 20%.
■ The value in brackets in the table indicates the motor power for a unit with 6 rows of coils.
■ The noise values in the preceding table are measured at a distance of 1 m from the unit in a state certified standard semi-anechoic room according to the GBT 9068-1988 standard.
■ If the external total pressure value of the unit used in model selection is large, the air flow will be large, leading to noise and water spray. Therefore, carefully determine the air duct resistance.
■ The coil loop form varies from a full air-return unit to a full fresh air unit. Mark the air inlet condition at purchase. Specify R for a full air-return unit and F for a full fresh air unit. EK provides model
selection software for special requirements. For specific parameters, see the model selection result.
The EKSW cabinet-type Air Handling unit is a product designed by EK air conditioner based on the air conditioner market and endpoint product features in China. The unit integrates a single-wall structure box, efficient forward fan, and fine processed coils. Secondary design is performed for the unit by using special EK air conditioner model selection software to better meet the requirements of customers for horizontal and vertical Air Handling units, saving indoor room. This product may widely apply to central air conditioner projects such as hotels, malls, airports, hospitals, factories, scientific research organs, and office buildings. It is especially applicable to scenarios with confined installation space and high requirements for noise such as reconstruction on obsolete buildings.
Cutting-edge manufacturing techniques and production devices are used. High-quality air conditioner copper tubes are connected to hyperbolic hydrophilic aluminum plate-fins through mechanical expanding so that the copper tubes and fins match, achieving optimal heat exchange for coils and ensuring efficient running of the unit. Coils of different specifications and loop forms are available to provide optimal running solutions in all conditions and meet various Air Handling requirements for users. The unit has a high external total pressure, a large cooling capacity, a small volume, and a simple structure, facilitating installation and repair.
