南方农村新型住宅节能燃煤灶供暖的可行性

Feasibility of Energy-saving Coal-fired Range Heating in Southern Rural New House

分析南方农村新型住宅建筑特点与居民供暖习惯,提出利用节能燃煤灶局部供暖(供暖房间为小卧室、大卧室、起居室),对供暖系统进行介绍。选取典型平层新型住宅,在设定供暖室内计算温度(8:00—20:00设定为14℃,20:00—次日8:00设定为10℃)条件下,测算供暖房间围护结构耗热量。根据用户燃煤(蜂窝煤)习惯计算得到的供热量存在缺口,不足部分可通过燃用蜂窝煤、电辅助加热、燃用沼气进行热补偿。若农户家中建有沼气池,在3种热补偿方式中,燃用沼气的费用最低,其次是燃用蜂窝煤,电辅助加热的费用最高。

The architectural characteristics of new houses in southern rural areas and the heating habits of residents are analyzed. The local heating with energy-saving coal-fired range is proposed, in which heating rooms include small bedroom, large bedroom and living room, and the heating system is introduced. The typical single-story house is selected, and the heat consumption of the building envelope of heating room is calculated under the given condition of heating indoor calculation temperature （14 ℃ 8 am-8 pm and 10 ℃ 8 pm-8 am）. The heating quantity calculated is insuffi- cient based on user coal （honeycomb briquettes） habits, which can be compensated by burning honeycomb briquettes, electric auxiliary heating and burning bio- gas. If farmers have biogas digesters, in three thermal compensation methods, the cost of biogas is the lowest, followed by burning honeycomb briquettes, and the cost of electric auxiliary heating is the highest.
