Cleanliness of ventilation ducts, indoor space and AHU

Paper deals with analysis of cleanliness air conditioning duct for various stages of construction. There were taken samples and these were analyzed for different type of storage duct on construction. They are compared differences between the "right" stored duct and unprotected duct including the actual interior space and air handling units serving. In the conclusion of this article is summarized the impact of carryover dirt from the duct and an air handling unit to the ventilation system.
