What is the typical indoor relative humidity range recommended for comfort in HVAC systems?

• A. 10% to 30%
• B. 30% to 50%
• C. 50% to 70%
• D. 70% to 90%

Answer: (B)

The typical indoor relative humidity range recommended for comfort in HVAC systems is between 30% to 50%. This range is ideal for human comfort as it helps to prevent both excessive dryness and excessive moisture in indoor environments. When humidity is too low, it can lead to dry skin, irritations in the respiratory system, and discomfort. Conversely, high humidity levels can cause discomfort and promote the growth of mold and mildew, which can affect both health and property. Maintaining indoor relative humidity within the 30% to 50% range ensures a comfortable environment while also protecting building materials and furnishings from the adverse effects of moisture. This balance is crucial for the efficient performance of HVAC systems, as they are designed to effectively manage both temperature and humidity levels to create suitable living and working conditions.
