摘要
采用三维紊流k-ε模型,应用FLUENT软件对低温送风房间的气流组织和热环境进行了模拟。按照ISO7730标准,采用有效吹风感温度T_(ed),空气分布特性指标ADPI等指标对室内热舒适度进行评价。验证采用常规的送风末端和低温送风相结合的气流组织模式的可行性,同时为空调室内气流组织形式的优化设计及舒适性提供依据。
Adopting turblulence model, numerical simulation of ventilated room＇s velocity and temperature field were applied by FLUENT. According to the ISO7730 standard, evaluation of indoor thermal comfort is carried out using Effective Draft Temperature （Ted）, Air Distribution Profile Index （ADPI）, etc. The feasibility of the normal air-supply terminal and low-temperature air-supply has been verified which will help the optimum design of the air distribution and comfortably study in the compartment with air conditioner.
