What is the main function of air conditioning in a building?

The primary function of air conditioning in a building is to cool the air, thereby enhancing comfort during warmer months. While cooling water for circulation can be a part of certain systems, the overarching and most discernible role of air conditioning is air cooling, not just water cooling.

Air conditioning systems are designed to remove heat and moisture from the indoor air, thus providing a controlled and comfortable environment. Additionally, they can help in regulating humidity levels, maintaining air quality through filtration, and providing ventilation, but these processes are secondary to their main role, which is cooling the air itself.

Understanding the main function is critical as it informs not only the operation of the system but also the broader design considerations of HVAC (heating, ventilation, and air conditioning) systems in ensuring occupant comfort and health within a building structure.
