AHU cooling coil


An AHU (air handling unit) cooling coil is a type of heat exchanger used in HVAC systems to cool and dehumidify the air passing through the unit. The cooling coil is typically located within the AHU and is connected to a chiller or other cooling system that circulates chilled water through the coil to remove heat from the air passing over it.

AHU cooling coils come in a variety of sizes and configurations, depending on the specific application and the cooling requirements of the space being served. The coils are typically made of copper or aluminum tubing with aluminum or copper fins, and are designed to provide efficient heat transfer while minimizing pressure drop and energy consumption.


AHU cooling coil


When selecting an AHU cooling coil, it's important to consider several factors, including:

Capacity: The capacity of the cooling coil should be selected based on the cooling load of the space being served. This will typically be calculated based on factors such as the size and orientation of the space, the number of occupants, and the amount of heat generated by equipment and lighting.

Airflow: The airflow rate through the AHU should be carefully controlled to ensure optimal heat transfer and dehumidification. The cooling coil should be designed to provide the required cooling capacity while minimizing pressure drop and energy consumption.

Material: The material of the cooling coil should be appropriate for the application and environment. Copper and aluminum are commonly used materials for the tubing and fins, as they provide good heat transfer properties and are resistant to corrosion.

Efficiency: The efficiency of the cooling coil can be improved by using advanced materials or coatings, such as hydrophilic coatings, that improve heat transfer and reduce the buildup of contaminants and debris.

Maintenance: The cooling coil should be designed for easy cleaning and maintenance, to ensure long-term performance and minimize downtime.

By considering these factors and working with a knowledgeable HVAC supplier or manufacturer, an AHU cooling coil can be selected and installed to provide efficient and effective cooling and dehumidification for a wide range of HVAC applications.

AHU cooling coil material

The material used for AHU (air handling unit) cooling coils can vary depending on the specific application and environment. However, the most common materials used for AHU cooling coils are copper and aluminum.

Copper is a popular choice for AHU cooling coils because it has excellent heat transfer properties and is highly resistant to corrosion. Copper is also durable and easy to work with, making it a good choice for manufacturing and installation.

Aluminum is also a popular material for AHU cooling coils because it is lightweight and has good heat transfer properties. However, aluminum is less durable than copper and is more prone to corrosion. To address this issue, aluminum coils can be treated or coated to improve corrosion resistance.

In some cases, other materials such as stainless steel or titanium may be used for AHU cooling coils, depending on the specific requirements of the application. For example, stainless steel may be used in applications where corrosion is a concern, such as in marine or coastal environments.

When selecting the material for an AHU cooling coil, it's important to consider the specific requirements of the application, such as the expected operating conditions, the required heat transfer rate, and the potential for corrosion or other types of damage. By selecting the appropriate material and working with a knowledgeable HVAC supplier or manufacturer, an AHU cooling coil can be designed and installed to provide efficient and effective cooling for a wide range of applications.
