摘　　要：针对农村特点,供暖能耗高且环境差,效果无法保证,以此为背景对农村供暖加以研究,通过合理设置外墙及其他手段来降低能耗。以山东省某市的典型农宅为研究对象,利用建筑能耗模拟软件DeST-h完成了建模,模拟了不同窗墙比及附加阳光间前后建筑的能耗情况。结果表明:北向窗墙比与热负荷呈正相关,且对夏季冷负荷的影响更大;增设附加阳光间能够有效提高基础室温并降低建筑能耗,当窗墙比为0.2、阳光间深度为1.2时的全年累积冷热负荷节能率达到了22.8%。研究结果可为完善农村建筑节能设计规范提供参考。This paper mainly aims at the characteristics of rural areas,where heating energy consumption is high and the environment is poor,and the effect cannot be guaranteed.Based on this background,this paper studies rural heating and how to set external walls reasonably and other means to reduce energy consumption.Taking a typical farm house in Shandong Province as the research object,the building energy consumption simulation software DeST-h was used to simulate the building energy consumption before and after different window wall ratio and additional sunlight.The results show that the north window wall ratio is positively correlated with the heat load,and has a greater effect on the cooling load in summer.The addition of additional sunlight room can effectively increase the basic room temperature and reduce the building energy consumption.When the window to wall ratio is 0.2 and the sunlight room depth is 1.2,the annual cumulative cooling and heat load energy-saving rate reaches 22.8%.The research results can provide reference for improving the design code of rural building energy efficiency.
