重庆地区住宅典型供暖方式能耗分析

Energy consumption analysis of typical heating modes in Chongqing area

本文基于重庆地区逐时室外干球温度,采用动态理论计算的方法,以某住户为计算模型,针对燃气壁挂炉和房间空调器两种典型供暖方式进行供暖季逐月耗热量计算,结果表明:两种供暖方式的逐月累计耗热量分布规律基本一致,同时由于二者运行时间控制策略不同,燃气壁挂炉供暖的逐月耗热量远大于房间空调器供暖,二者单位供暖面积耗热量分别为112.9 kW·h/m^(2)和26.7 kW·h/m^(2),前者耗热量为后者4.23倍,12月、1月、2月三个月的累计供暖耗热量约占整个供暖季的七成。房间空调器供暖季单位供暖面积折合标准煤耗量为1.06 kg/m^(2),用电费用为5.7元/m^(2),壁挂炉供暖季单位供暖面积折合标准煤耗量为16.1 kg/m^(2),燃气费用为33.0元/m^(2),从节能和运行成本角度来看,重庆地区房间空调器供暖比燃气壁挂炉供暖具有明显优势。

In this paper,based on the hourly outdoor temperature in Chongqing area,dynamic theoretical calculation method is used to calculate the monthly heat consumption of wall mounted gas boiler heating and room air conditioner heating by one household.The results show:The monthly heat consumption distribution of the two heating modes is basically consistent.At the same time,the monthly heat consumption of wall mounted gas boiler is much higher than that of air conditioner due to the difference of the running time control strategies between them.The heat consumption per unit heating area of the two are 112.9kW·h/m^(2)和26.7kW·h/m^(2).The heat consumption of the former is4.23 times that of the latter.The heating load in December,January and February accounts for about 70%of the whole heating season.The unit heating area of the room air conditioner in the heating season is equivalent to the standard coal consumption of 1.06 kg/m^(2),the electricity consumption is 5.7 yuan/m^(2).The unit heating area of the wall mounted gas boiler in the heating season is equivalent to the standard coal consumption of 16.1kg/m^(2),and the gas consumption is 33.0 yuan/m^(2).The room air conditioner heating in Chongqing has obvious advantages over the wall mounted gas boiler heating from the perspective of energy conservation and operation cost.
