基于改进炕洞构造形式的大花洞火炕热舒适度

Thermal Comfort of Large Complexity Kang Based on Improving Kang Hole Structural Form

为了解决普遍存在的炕面温度极不均匀、热舒适度差的问题,将火炕从进烟口到出烟口的整个炕体作为研究对象,利用VENT技术对大花洞火炕的烟气流场分布、涡流状况进行模拟分析,对其烟道进行优化设计,得出两种优化设计模型,明显改善了现状火炕的烟气流场分布,大幅减少了涡流区面积,使更大范围的烟道炕洞、炕面板能够接触到高温烟气进而吸蓄、存储、释放烟气热量,大幅提升了火炕热舒适度。为火炕的优化设计提供了一种新的技术方法。

In order to solve the common problem of uneven temperature and poor thermal comfort on kang surface,regarding the smog entrance,the exit and the kang body as a whole research object,using the VENT technique to simulate the flow field distribution and eddy current situation analysis of large complexity kang cave,to the optimization design of the flue,two optimization design models were obtained,which significantly improve the smoke flow field distribution of present kang,and reduced the eddy zone area,it make a wider range of chimney flue and kang panel can come into contact with high temperature flue gas,in turn,absorbing,storing and releasing of the flue gas heat to improve environment thermal comfort,this will also provide a new technology method to achieve optimal design.
