Title:
ELLIPSOIDAL HOLLOW FLOOR SYSTEM-BASED AIRFLOW FLOW CONSTRUCTION METHOD AND AIRFLOW LOSS-BASED CALCULATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/185994
Kind Code:
A1
Abstract:
An ellipsoidal hollow floor system-based airflow flow construction method and an airflow loss-based calculation method. The airflow flow construction method comprises: an ellipsoidal hollow floor system-based smoke exhaust construction method for performing smoke exhaust, ventilation, air conditioning, and fire extinguishing of a hollow floor system. The airflow loss-based calculation method comprises: obtaining total loss for a football-shaped cavity and obtaining total airflow loss for a disk-shaped cavity. By using the floor system composed of ellipsoidal cavities, due to curved surface characteristics of inner walls of the cavities, compared to conventional cube-shaped cavities, the floor system composed of the ellipsoidal cavities has the advantages of small overall airflow flow energy loss, a good airflow flow effect, and small sudden contraction and sudden expansion energy losses, has a better effect than the conventional cube-shaped cavities when applied to the airflow flow of the hollow floor system, has certain fire-resistant properties compared to conventional open conduits, and has more economical and efficient applications with respect to indoor smoke exhaust, indoor ventilation, air conditioning, and fire extinguishing by introducing a fire extinguishing gas such as perfluorohexanone into the floor system.
