针对严寒地区冬季室内空气质量差和能耗居高不下双重问题,利用热管的高导热性设计出热管式定风量换气节能装置,并由FLUENT软件按照实际工程参数对室内气流组织进行模拟,再将其结果与风机盘管加新风系统进行对比。结果表明,两种情况下的房间速度分布基本相同,但温度分布有差异。综合室内温度分布、气流分布、节约能耗角度考虑,提出的新型装置具有较大的研究和推广价值。
In view of the dual problem of poor indoor air quality and high energy consumption in winter in cold region, the heat pipe type constant-volume ventilation device is designed by using the high thermal conductivity of the heat pipe. The FLUENT software simulates the indoor air flow structure according to the actual engineering parameters. Compare the results with the fan coil plus fresh air system. The results show that the room speed distribution is basically the same in both cases, but the temperature distribution is different. Considering the indoor temperature distribution, air flow distribution and energy conservation, the proposed new device has great research and popularization value.
