低温空气源热泵在高原高寒地区铁路车站的应用研究

Study on application of low temperature air-source heat pump to railway station in plateau frigid region

在我国近期大力推进控制污染物排放的背景下,新能源的应用显得迫在眉睫。本文以新建拉日线日喀则车站单身宿舍和兰州至乌鲁木齐第二双线清泉南站生活辅助房屋为例,对低温空气源热泵机组采暖方案进行技术和经济分析。结果表明,经低温条件下热泵机组制热量衰减及海拔修正后,低温空气源热泵系统技术可行;在高原高寒地区铁路车站缺少集中热源的情况下,与燃油锅炉及电采暖系统相比,低温空气源热泵系统无论初投资还是运行费用均最低,值得推广。

In the background of pollutant discharge control in China,the application of new energy is imminent. T aking the new Shigatse station single dormitory in Lari line and the spring south station living auxiliary building in Lanzhou to U rumqi second double line as an example,this paper analyzed the technology and economy for heating scheme of low temperature air source heat pump units. T he results showed that low temperature air source heat pump system is feasible after the heating capacity attenuation and attitude correction of heat pump units in low temperature,and the initial investment and operating costs of low temperature air source heat pump system are the lowest and worthy of promotion compared with the oil fired boiler and electric heating system under the condition of centralized heat source lack in railw ay station of plateau frigid region.
