Conducted air conditioning analysis during heating when cold drafts from the circular roof glass surface became an issue.
The analysis of the thermal environment in a warm water pool focused on air conditioning during heating, where the cold draft from the circular roof glass surface becomes a problem. The temperature distribution in large spaces tends to be more disturbed compared to smaller spaces. This is generally because large spaces are more prone to uneven wall infiltration and heat loads, making it difficult for the conditioned air to circulate in the occupied zone. Recent air conditioning analyses have become capable of accurately simulating actual properties, including the three-dimensional shape of the structure, the behavior of supply and return air, and various heat loads.

basic information
【Analysis Model】 - Since the behavior of airflow in the space could not be predicted in advance, the grid division of the analysis model was set as uniformly as possible throughout the entire space. - The number of grids is 82×74×34=206,312. - A relatively small-scale analysis. - The air conditioning is mainly from nozzles near the ceiling and from posts above the main stand. - Warm air is also supplied to the space from convectors near the perimeter of the arena floor. 【Analysis Results】 - In the winter air conditioning analysis, the thermal environment becomes uniform. - A major goal is to eliminate cold drafts from the roof glass surface. - The aim is not to completely eliminate cold drafts, but to control the air conditioning so that the drop position of the cold draft is at the surface of the pool water rather than the arena floor. - There are no significant disturbances in the large flow field, and a comfortable environment is maintained both in the stand area and the arena area. ● For more details, please contact us or download the catalog.
