What is the purpose of the reheat coil in the AHU?

The purpose of the reheat coil in the AHU (Air Handling Unit) is as follows:

It is used to adjust the temperature of the air precisely. After the initial cooling or other conditioning processes, the reheat coil can add heat back to the air to fine-tune the final temperature output. This helps in achieving a more accurate and comfortable temperature in the conditioned space. It also allows for better control over the temperature gradient within different zones of a building or system. 

For instance, if the cooled air is too cold for a particular area or application, the reheat coil can be activated to bring the temperature up to the desired level. Additionally, it can be used to prevent overcooling and subsequent condensation or other issues. It provides flexibility in temperature management within the HVAC system to meet specific requirements and maintain optimal conditions.
