Abstract

The ventilation load from outdoor air intake is one of the dominant heating/cooling loads in buildings; on the other hand, increased ventilation rates help decrease the percentage of subjects dissatisfied with the indoor air quality (IAQ) and improve workplace productivity. In order to optimize the ventilation rate, integrating an energy recovery ventilator (ERV) with a CO2 demand-controlled algorithm is an effective measure for indoor environmental design. The overarching objective of this study was to develop an optimized ERV with a CO2 demand-controlled algorithm. The residual lifetime of CO2 generated at a local point in an office space was measured to improve the feedback algorithm for sensing CO2 at the local point and adjusting the ventilation rate. Computational fluid dynamics (CFD) was also carried out to investigate the residual lifetime distribution in the target space.
