摘　　要：为了比较供暖装置在不同气候条件下的性能,建立了能耗、经济和环保性模型,分析了CO_(2)跨临界空气源热泵(ASHP_(CO_(2)))、R410A空气源热泵(ASHP R410A)、燃气壁挂炉(WGH)以及电加热取暖器(DEH)4种供暖装置。结果表明:ASHP_(CO_(2))的能耗较低,相比DEH的能耗最大减少了81.2%;ASHP R410A和WGH的经济性较好,相比DEH的运行总成本分别最大减少了60%和52.1%;WGH的环保性最佳,其次是ASHP_(CO_(2)),ASHP_(CO_(2))在上海的PM_(2.5)排放量比DEH低75.2%;除长沙以外,4种供暖装置的能耗、运行成本及污染物排放量均随地区纬度的降低而降低;ASHP_(CO_(2))在上海地区的能耗比哈尔滨降低64%;ASHP_(R410A)在上海地区15 a内运行总成本比哈尔滨减少41%;WGH在上海的SO_(2)、NO_(x)和PM_(2.5)排放量比北京分别下降17.4%、34.3%和34.3%;按照综合性能排序,依次为WGH、ASHP R410A、ASHP_(CO_(2))、DEH;哈尔滨等严寒地区采用WGH具有优势,其他地区可采用ASHP R410A,ASHP_(CO_(2))在西安地区的综合指数高于其他地区。In order to compare the performance of heating devices under different climatic conditions,the energy consumption,economic and environmental performance models were established.Four kinds of heating devices were analyzed,including CO_(2) transcritical air source heat pump(ASHP_(CO_(2))),R410A air source heat pump(ASHP R410A),gas wall hanging furnace(WGH)and electric heating heater(DEH).The results show that ASHP_(CO_(2)) has the lower energy consumption,which is 81.2%lower than that of DEH.ASHP_(R410A) and WGH have better economy,and their minimum total operating costs are 60%and 52.1%lower than that of DEH.WGH has the best environmental performance,followed by ASHP_(CO_(2))The PM_(2.5)emission of ASHP_(CO_(2))in Shanghai is 75.2%lower than that of DEH.The energy consumption,operation costs and pollutant emissions of the four heating devices reduce with the decrease of regional latitude in all the typical cities except Changsha.The energy consumption of ASHP_(CO_(2))in Shanghai is 64%lower than that in Harbin.The total operating cost of ASHP R410A in Shanghai for 15 years is 41%less than that in Harbin.The SO_(2),NO_(x)and PM_(2.5)emissions of WGH in Shanghai are 17.4%,34.3%and 34.3%lower that those in Beijing,respectively.The four devices ranked from best to worst comprehensive performance are WGH,ASHP R410A,ASHP_(CO_(2))and DEH.WGH is suitable for cold regions such as Harbin.ASHP R410A can be used in other regions.The comprehensive index of ASHP_(CO_(2))in Xi'an is higher than that in other cities.
