How do psychrometric processes affect indoor air quality (IAQ) in buildings?

Psychrometric processes play a crucial role in maintaining good indoor air quality (IAQ) in buildings. The temperature, humidity, and air movement patterns in a building can significantly impact IAQ by influencing the growth and spread of pollutants, such as mold and bacteria. For example, high humidity levels can lead to mold growth, while poor air circulation can cause the buildup of pollutants. By controlling psychrometric processes, HVAC systems can help maintain good IAQ by providing a comfortable and healthy indoor environment.
