中文摘要:

      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,本文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,本文提出的新型装置具有较大的研究和推广价值。

英文摘要:

      For the problems of poor indoor air quality and high energy consumption in a severe cold region in winter, we design a heat pipe device with constant air volume (CAV) and energy saving device according to the thermal properties of a heat pipe in this paper; place the device within a room wall, and two ends of the device connected to the two inlet and outlet ports of the wall separately, one is a fresh air inlet port, the other is a air outlet port; and simulate the indoor airflow characteristic in the condition of similar actual boundary requirement by FLUENT software, then the properties from the heat pipe device simulation are contrasted with those from a fan coil air condition system. The results show that flow velocity dynamic curves are virtually identical while the temperature distribution is different. Taking temperature distribution, airstream distribution and energy consumption into account, the new device presented in this study has strong research and promotion value.
