We will conduct thermal airflow simulations in the basic design phase plan.
In recent years, there have been many cases where natural ventilation utilizing outside air is actively incorporated during the intermediate period and other times. Among these, a ventilation method that uses shafts installed within the building as exhaust and supply air systems has been considered from the basic design stage to efficiently carry out natural ventilation. The selection of appropriate locations and sizes for supply and exhaust openings is of great importance, and conducting thermal airflow simulations allows for insights into the overall operation of the building. In this analysis, we assumed windy conditions and conducted thermal airflow simulations based on the plans from the basic design stage. For more details, please download the catalog.

basic information
【Analysis Model and Conditions】 - Detailed modeling of the internal space of a building measuring 48.0m × 24.0m and 16.0m high (equivalent to 4 floors). - The number of grids is 196 × 121 × 83 = 1,968,428. - Air supply vents are installed on three exterior walls of each floor from the 1st to the 4th floor. - For the shafts leading to the outdoor exhaust vents, two shafts are provided with a height equivalent to one floor above the roof, with grilles installed on three sides similar to the air supply vents. - Exhaust vents from the indoor space to the shafts have transom openings installed on three sides of the shafts from the 1st to the 4th floor. - Indoor thermal loads consider internal heat generation from humans, equipment, and other sources, as well as conduction and solar heat loads. - The external wind is set at a 45-degree angle to the long side of the building, with a wind speed of 3.5 m/sec. 【Analysis Results】 - A similar temperature distribution is observed from the 1st to the 4th floor, with the highest temperature on the 4th floor. - Airflow generated by the air supply vents and the convective indoor thermal loads occurs on each floor, but efficient ventilation is lacking. - The results of this analysis demonstrate that the position and size of the air supply and exhaust vents are not appropriate. → In the next step, it is necessary to examine the position and size of the air supply and exhaust vents, including the opening ratio of each vent. ● For more details, please contact us or download the catalog.
