A Smart Logic for Conference Room Terminal Box of Single Duct VAV System
MetadataShow full item record
In a modern office building, most occupied rooms are relatively isolated from the outdoor air climate conditions. To ensure acceptable indoor air quality (IAQ), ASHRAE 62 explains how to design and construct a space that has a proper quantity of ventilation air. Conference room presents a challenge to the designer due to its high ventilation requirement during occupancy. The minimum air flow rate set point for a conference room has to satisfy fresh air demand under the worst conditions. At the same time, the minimum outside intake ratio for AHU side should be as low as possible to save energy. This study presents a smart logic to solve the confliction while improving thermal environment and saving energy consumption. The new control sequence is evaluated by simulation. The thermal performance and the energy consumption of conventional and improved control sequences are compared by analyzing the simulation results.
