Abstract

It is essential to control humidity level to maintain indoor air quality of multi-family residential buildings preventing condensation and mold growth. Exhaust and ventilation systems can have indoor humidity control performance, but it can affect occupant’s comfort and energy consumption associated with ventilation devices. Therefore, it needs to optimize the strategies to operate exhaust or ventilation systems of typical Korean multi-family residential buildings. This study carried out experiments for various combinations of exhaust and ventilation systems to control indoor humidity level. As a result, it was effective to use the kitchen hood and the energy recovery ventilator simultaneously when detecting humidity level increase, then to use only the ERV after reaching the peak increment of indoor humidity level. The experiments showed that the modified control algorithm could provide controlling indoor humidity level effectively with lower noise generation and electricity consumption than using the kitchen hood and multiple ventilation systems. This paper shows the importance of considering various parameters comprehensively to optimize indoor air quality control strategy. The results of this study will be useful as a control strategy for indoor air quality when planning a control system with sensors to operate exhaust and ventilation systems effectively in multi-family residential buildings.
