冷剂辐射式系统地埋管间距对房间热舒适影响

摘要

本文以郑州市一采用冷剂辐射式供冷系统的办公室样板间为对象, 采用Airpak软件, 用数学模拟的方法研究了标准热泵工况下, 蒸发毛细盘管间距分别为80 mm, 100 mm和120 mm时房间的PMV云图, PPD云图以及温度场, 并对房间的热舒适性进行了分析.模拟结果表明:蒸发盘管管间距对房间热舒适性影响显著, 且在模拟范围内, 管间距越大, 房间热舒适性好的范围也越大.%Taking a radiant cooling system with cold agent in Zhengzhou office as object, the Airpak software was applied to study the indoor PMV and PPD in standard heat pump working conditions with capillary evaporation coil spacing as 80 mm, 100 mm and 80 mm. The simulation results show that the evaporating tube spacing significantly influence on thermal comfort of room. When the capillary coil spacing within the scope of evaporation in the simulation, the greater tube spacing has the better thermal comfort range.
