Title: Numerical Simulation of Indoor Velocity Field in Winter Effected by Jet Flow Velocity Attached on Exterior Wall
Abstract: In this paper, ANSYS-CFX computational fluid software was applied for the study of numerical simulation, to explore the influences of the vertical attached jet air flow on outside wall formed by the slot outlet to the indoor temperature field and velocity field. By analysis and study of the indoor velocity field under different supply air speeds distribution, the new type air conditioning air supply might be found, and the uncomfortable degree caused by vertical temperature differences and cold wall nonuniform radiation could be reduced. Thereby, the double-index of the energy conservation and comfortable in the office building could be matched for business building, hotel and other public buildings. The result of this study indicated that,in order to achieve the goal of saving energy and improving indoor thermal comfort, the appropriate supply air velocity should be determined according to the actual conditions in heat ventilation air conditioning application.
