What is one characteristic of HVAC systems that is affected by relative humidity?

One characteristic of HVAC systems that is significantly affected by relative humidity is comfort levels. Relative humidity plays a crucial role in how we perceive temperature and overall comfort in indoor environments. When humidity levels are too high, the air feels warmer than it actually is because the body's ability to cool itself through perspiration is diminished. Conversely, when humidity levels are too low, it can lead to dry skin, irritations, and discomfort.

HVAC systems are designed to regulate both temperature and humidity to maintain a comfortable indoor environment. Achieving the right balance is essential for occupant comfort, making it a vital aspect of HVAC system performance. This interplay between humidity and comfort levels underscores the importance of monitoring and controlling relative humidity within HVAC systems.
