What can result from a continuous lack of fresh air in an HVAC system?

• A. Better air circulation
• B. Increased comfort levels
• C. Deterioration of indoor air quality
• D. Enhanced cooling performance

Answer: (C)

A continuous lack of fresh air in an HVAC system can lead to the deterioration of indoor air quality. Fresh air is essential for diluting indoor pollutants, such as carbon dioxide, volatile organic compounds (VOCs), and other harmful substances produced by occupants, building materials, and daily activities. When fresh air is lacking, these pollutants can accumulate, leading to decreased air quality, which can consequently result in discomfort, health issues, and various respiratory problems for the occupants. Other options such as better air circulation, increased comfort levels, and enhanced cooling performance misrepresent the effects of insufficient fresh air. In fact, without adequate ventilation, air circulation may be compromised, comfort levels may decrease due to stale air, and cooling performance may suffer as the system has to work harder to maintain desired temperature and humidity levels, ultimately leading to inefficiencies. Thus, ensuring a consistent supply of fresh air is crucial for maintaining healthy and comfortable indoor environments.
