摘要
采用K-ε湍流模型对病房内三维紊流流动和传热进行了数值模拟,计算得到单元式集中空调系统与全热换热器在三种不同运行模式下室内热舒适性指标PMV及PPD的分布情况。通过比较不同运行模式下人体活动区域内的热舒适性指标分布情况,确定空调系统与全热换热器的节能运行方案。
By K-εturbulence model, the indoor fluid flow and heat transfer were analyzed. By the study of flow field and thermal comfort, reasonable united run scheme was put forward. It promise a new approach to guarantee indoor environment safety, health, thermal comfort and energy saving.
