摘　　要：针对内蒙古蒙西地区实行清洁供暖采用峰谷分时电价政策,探究综合经济性最优的“煤改电”采暖系统以及峰谷时段运行时间组成。以内蒙古包头某居民住宅为研究对象,利用TRNSYS软件搭建了直热式电锅炉、太阳能+电辅助、超低温空气源热泵3种热源“峰谷分时电价”采暖系统模型,进行仿真模拟计算;通过对3种采暖模式的初装费、运行费、设备维护这3个因素进行综合经济性评价,结果表明:电锅炉、太阳能、空气源热泵3个系统峰谷电运行时间组成分别为3:7、2:8和3:7;从第3年开始,空气源采暖系统综合经济性凸显;第7年开始,太阳能采暖系统综合经济性才首次超过直热式电锅炉。若单纯考虑采暖经济性,建议首选空气源热泵采暖系统,直热式电锅炉为第二选项。该结果为后续“煤改电”的实施提供现实参考。In view of the implementation of clean heating and the peak-and-valley time-of-use electricity price policy in Mengxi area of Inner Mongolia.In order to explore the optimal system and the operation time composition of the peak and valley period.This paper takes a residential house in Baotou,Inner Mongolia as the research object,and uses TRNSYS to build three kinds of heating system models based on peak and valley time:electric boiler heating system,solar heating system with electrically aided heater and air source heat pump heating system.And comprehensive economic evaluation will be judged by the three factors of initial installation cost,operating cost,equipment maintenance.The results show that the composition of peak and valley power operation time about electric boiler,solar with electrically aided heater and air source heat pump heating system are 3:7,2:8 and 3:7 respectively.The comprehensive economic efficiency of air source heat pump heating systems has become prominent at the third year;and solar heating systems became higher than direct heating electric boilers at the seventh year.It is recommended that air source heat pump heating system was the best option,direct heating electric boilers be the second.This result provides practical reference value for the implementation of the“coal to electricity”plan in the future.
