Why is a heating coil used in AHU?

A heating coil is used in an AHU for several key reasons:

Firstly, it provides a means to increase the temperature of the air that passes through it. This is essential for maintaining a comfortable indoor environment, especially in colder weather or when a specific temperature setpoint needs to be achieved. It helps to offset heat losses and ensure that the air supplied to a space is warm enough.

Secondly, it allows for fine-tuning of the temperature within the AHU system. By controlling the heat input to the coil, the output air temperature can be precisely adjusted. This is important for meeting the diverse temperature requirements of different areas or applications served by the AHU.

Additionally, it can be used to compensate for temperature variations that may occur due to external factors or changes in the system's operation.

For instance, in a commercial building, the heating coil in the AHU helps to warm the incoming air during the winter months, ensuring that the occupants feel comfortable. It also provides the flexibility to adjust the temperature based on occupancy levels or specific zone requirements. The use of a heating coil in the AHU is a crucial component in achieving effective and efficient temperature control in an HVAC system.
