Today, most modern buildings are equipped with a variable air volume (VAV) air distribution system. Traditionally, this type of system raises concern for the correct amount of outdoor air being distributed at low load conditions. Therefore, closer attention should be focused on the quantity of outdoor air ventilation both entering the system and being delivered to the interior spaces. This articles describes the dynamics of an air handling unit serving multiple spaces under variable load conditions. Also discussed is the variable load effect on the minimum outdoor air intake quantity required to maintain acceptable indoor air quality. Calculations were done for a single air handling unit that serves spaces with significantly different outdoor air requirements. The office/conference room combination was chosen to analyze the impact of variable load conditions in the office area on the overall system outdoor air intake requirements.
