摘要
太阳能热风楼板供暖系统具有建造维护成本低、运行使用方便、且低温不易冻结等优点,适宜于在青藏高原地区住宅建筑中应用。本研究针对3种不同的热风供暖系统(直接送热风系统、楼板开式送风系统及楼板闭式辐射系统)在青藏高原3种典型气候地区(拉萨等高辐射、寒冷(A)地区,玉树等中辐射、严寒(B)地区,兴海等低辐射、严寒(A)地区),以及不同建筑节能水平条件下的技术适宜性进行分析。得到3种太阳能热风系统的技术适用条件,为太阳能热风楼板供暖技术在青藏高原地区大面积推广给出了可供选择的技术方案。
Solar hot air floor heating system has the advantages of low construction and maintenance costs,convenient operation and freeze resistance at low temperatures,which makes it suitable for application in residential buildings in Qinghai-Tibet Plateau.This study aimed at three different hot air heating systems(direct hot air supply system,hot air floor open supply system and hot air floor closed radiation system)in three typical climatic regions of Qinghai-Tibet Plateau high-radiation and cold(A)areas like Lhasa;medium-radiation and severe cold(B)areas like Yushu;low-radiation and severe cold(A)areas like Xinghai),and the technical suitability under different building energy-saving levels were analyzed.As a result,the technical application conditions of the three solar hot air systems were obtained,and an alternative technical solution for large-scale promotion of the solar hot air floor heating technology in Qinghai-Tibet Plateau is given.
