地板辐射换热运行及模拟分析

The Analysis of the Operation and Simulation of the Floor Radiant Heat Transfer

合理的空调方式不仅更加舒适,还可以节约能源。介绍了地板辐射换热(供冷/供暖)的原理及特点,对地板辐射供暖房间进行数值模拟,进而得到房间的温度场和速度场,并利用PMV热舒适指标进行分析。地板辐射换热加置换通风是比较理想的空气调节方式。地板辐射供暖已经得到广泛应用,在夏季使用地板辐射进行供冷可以使全年共用一套末端设备,具有良好的经济性和舒适性。

Reasonable air conditioning mode is not only more comfortable,but also can save energy.This paper introduces the principle and characteristic of the floor radiant heat(cooling/heating),for floor radiant heating room to carry on the numerical simulation,then get the temperature field and velocity field of the room,and analyzing by the thermal comfort index PMV.Floor radiant heat transfer with displacement ventilation is ideal air conditioning mode.Floor radiant heating has been widely used,we can use the floor radiant cooling in the summer to share a set of terminal equipment all the year round,it has the good economy and comfo rt.
