What is Air Supply Method and Indoor Environment about?
A ventilation jet diffuser is characterized by parameters such as diffuser effec tive area, diffuser dimension, diffuser position, air supply direction, flow rate, and air temperature. This paper studies the influence of the parameters of a jet diffuser on the airflow pattern, indoor air quality, and draft risk in an office with a jet diffuser on the rear wall near the ceiling. The presentation of furni ture and occupants in the office is included in the numerical simulation. The structure of a jet diffuser used in practice is complicated. Therefore, a simpli fied method is introduced to simulate the diffuser. The method is compared with the experimental data. The agreement between the simulations and the measurements is reasonably good. The distributions of the air velocity, tem perature, contaminant concentration, and percentage dissatisfied people due to draft risk with different parameters of the diffuser are numerically pre dicted by the k-e model of turbulence. The effect of turbulence intensity is taken into account in the computation of draft risk. It has been found that the angle between the jet and the ceiling should be in the range from 20 to 60°C. The effective flow are
