Literature Review of Displacement Ventilation
MetadataShow full item record
Various sources and search engines were used to find the technical research and literature by using specific keywords to search for the relevant reports or browsing through the list of documents. First, the 78 references from the book, “System Performance Evaluation and Design Guidelines for Displacement Ventilation” by Chen and Clicksman (2003), were used to begin the literature search. Their references include papers, articles, and web sites presenting major contributions to the understanding and development of the displacement ventilation technology and design. Other literature search methods were utilized.
DescriptionThis report reviews the literature about displacement ventilation. It begins with a summary of literature search methods and the number of papers and articles found. In summary, displacement ventilation systems may provide better indoor air quality than conventional mixing ventilation systems and maintain a thermally comfortable indoor environment. Displacement ventilation keeps the mean age of air in a room younger than does the conventional mixing ventilation. Due to the potential existence of draft and the large temperature stratification with displacement ventilation, a designer needs a careful attention to the air temperature distribution in spaces. A recent design guideline developed by Chen and Glicksman (2003) can be used for the design of the displacement ventilation systems for buildings in the U.S.
