| Abstract | ||
| This research deals with the study of the three-dimensional heat transfer and air flow for enclosed space air conditioning with cold ceiling shower. Numerical modeling has been used to analyze the effect of ceiling air conditioning on temperature and air velocity distribution . The analyses showed the influence of these factors on the air circulation and the related temperature distributions through enclosed space. The modeling and simulation of a space with using standard k-ω turbulence model for modeling air flow velocities and indoor temperatures with its gradients are analyzed. It is shown that it is possible to save good flow distributions, at the same time maintaining the conditions of thermal comfort in the room which is the main goal. This work indicated that the best penetration of cold flow is for the plane passes through the center of the ceiling duct in which the penetration area for this case covers a very wide range in room these planes are modeled using specialized computational fluid dynamics (CFD) software ANSYS /FLUENT 13. | ||
