Abstract

A dual-mode demand control ventilation strategy was established targeting at use in buildings where the number of occupants varies frequently. The first contaminant chosen for sensor control is CO₂ and the second is a non-occupant-related indoor pollutant which indicates the demand of fresh air to dilute the non-occupant-related indoor contaminants. Experiments were conducted to verify the performance of this control strategy. The experimental results showed that an acceptable indoor air quality could be obtained. More than 90% of the occupants thought that the indoor air quality was acceptable. Comparing with the original fixed-rate ventilation control strategy, about 8.3-28.3% of the daily electrical energy could be saved.
