Dedicated outdoor air system in the THIC air-conditioning system (2): Determination of supply air parameters

Presents the determination process of outdoor air volume and humidity ratio of supply air parameters. With a practical building model, calculates the moisture load of each functional room. Gives the important suggestions for determination of outdoor air volume and supply air parameters. The results show that the moisture load from outdoor air infiltration in low occupant density room should be considered. Additionally, the outdoor humidity ratio and average wind speed, the air tightness of building envelope and the height of the building have significant effects on the moisture load from outdoor air infiltration.
