Chilled Water Cooling Coil for Ahu

The chilled water cooling coil has a key role to play in an air-conditioning system. It reduces the temperature of the air by exchanging heat with the hot air passing through the coil by means of low-temperature chilled water flowing inside.

This type of cooling coil usually consists of a series of copper or aluminium tubes with fins on the outside to increase the heat exchange area. Their design and performance have a direct impact on the cooling effectiveness and energy efficiency of the AHU.

For example, in the air-conditioning system of a large commercial building, a highly efficient chilled water cooling coil can quickly cool the air entering the room to the right temperature, providing a comfortable environment for people. In industrial production, precise temperature control of chilled water cooling coils is essential to ensure the normal operation of production equipment and product quality.

In addition, choosing the right chilled water cooling coil requires consideration of a variety of factors such as water flow rate, pressure drop, tube material, fin type, etc. to meet the needs of different applications.

The choice of material for chilled water cooling coils requires a combination of the following factors:

1. Thermal conductivity:

Good thermal conductivity contributes to more efficient heat exchange. For example, copper has excellent thermal conductivity, can quickly transfer heat, improve cooling efficiency.

2. Corrosion resistance:

As the chilled water may contain impurities or chemicals, the material needs to have the ability to resist corrosion in order to extend the service life of the coil. For example, stainless steel can resist corrosion to a certain extent.

3. Strength and durability:

To be able to withstand the pressure and possible vibration when the system is in operation. Tubes like copper usually have high strength and are less prone to breakage.

4. Cost:

Prices vary considerably from material to material. The cost factor needs to be considered while meeting the performance requirements. For example, aluminium tubes are relatively inexpensive, but may not perform as well as copper tubes in some areas.

5. Machinability:

Ease of fabrication and installation. Certain materials may be easier to bend, solder or join.

6. Weight:

For some installation environments where weight is important, lighter materials may be more suitable, such as aluminium coils.

7. Compatibility:

Compatibility with other components and chemical additives in the chilled water system. If the material reacts adversely with other parts, it can affect the performance and life of the entire system.
