辐射供冷用于某热敏电阻检测室的数值模拟研究

Numerical Simulation Study of Radiant Cooling in a Thermistor Testing Room

以南京地区某热敏电阻检测室为研究对象,建立了物理模型及数学模型,利用商用CFD软件FLUENT对分别采用辐射供冷与均匀送风两种方案下检测室内的温度场进行了数值计算与对比分析,并在此基础上提出了一种改进方案。模拟结果表明:将辐射供冷用于该检测室空调系统,在良好的设计条件下不仅能取得较为理想的工艺环境,同时也能达到良好的节能效果,是值得推广和应用的。

The physical and mathematical model for a thermistor testing room in Nanjing is established. The temperature field under two different schemes of radiant cooling and uniform air supply in the room is simulated and analysized by using the com- mercial CFD software FLUENT. An improved scheme is proposed on this basis. The simulation results shows that ideal process environment and good energy saving effects can be obtained by using the radiant cooling system in this thermistor testing room un- der the design of the good conditions. It is worth popularizing and utilizing.
