冷辐射板布置方式对办公室热环境影响的模拟研究
Simulation Study on the Influence of Radiant Cooling Panel Layout on Office Thermal Environment
摘要
Abstract
Radiant cooling is often collaborated with displacement ventilation system to achieve good thermal comfort and energy conservation.When a radiant cooling/ displacement ventilation system is used in the office environment,the layout of the radiant cooling panels has effect on the indoor thermal environment.In this paper,simulations on the heat transfer process of four different layout ways of the radiant cooling panels in the office room,including in the ceiling,on the floor,on the upper-vertical walls and on the lower-vertical walls,were conducted by CFD method respectively via the software of Airpak.The corresponding indoor temperature field and flow field of the indoor air were obtained.Results show that among the four types of radiant cooling panel layout,the cooling efficiency of the case with the radiant cooling panels on the upper-vertical walls is the best,which has the smallest turbulent zone,the highest thermal stratification height and the lowest temperature in the occupied zone.关键词
