A NUMERICAL SIMULATION OF AN AIR CONDITIONING SYSTEM IN OFFICE USING WEAK AIRFLOW

摘要

The objective in this study is to evaluate thermal environment of a room with an advanced ceiling hidden type air-conditioner using numerical simulation. As the characteristic of the air-conditioner, it supplies a weak airflow from a large inlet to a room. Circulator fans are fixed on the ceiling. Numerical simulation is performed to a room with the air-conditioner. PMV is calculated from the obtained data and thermal sensation of the people is investigated. From the PMV distribution, it was found that this sensation was improved by the advanced air-conditioner.
