Evaluation of set points for moisture supply and volatile organic compounds as controlling parameters for demand controlled ventilation in multifamily houses

Abstract
The main purpose has been to evaluate existing set points (thresholds) and suggest proper set points, for the regulation of the air change rate in a demand controlled mechanical ventilation (DCV) system. The DCV is controlled by measurements in the supply and exhaust air of the vapor content and volatile organic compounds (VOCs) for each dwelling in multifamily houses. Results have been achieved through a literature review and laboratory tests. The threshold for the maximum ventilation rate (0.8 ac/h) should be set at 1000 ppm (CO2-eq.). Preferably, a minimum ventilation rate of 0.5 ac/h should be set with current thresholds (800-1000 ppm CO2-eq.). With a lower minimum ventilation rate (e.g. 0.1 ac/h) the lower threshold should be set at... (More)

With a lower minimum ventilation rate (e.g. 0.1 ac/h) the lower threshold should be set at 450 ppm (CO2-eq). In order to deal with heavy moisture production the threshold for the moisture supply is suggested to be set at 3 g/m3. (Less)
