Air movement through doorways - the influence of temperature and its control by forced airflow.

Describes research to study movement of air through fully or partially open doorways with and without influence of temperature, and to ascertain amount of supply air required toprevent this movement. Studies door openings of 0.10 to 104 m. wide and temperature differential of 0 to 12 deg.C. States that from these results critical areas in hospitals may be designed more effectively to given requirements.
