【摘要】 针对能源短缺和环境问题,结合一个工程实例,采用年度费用分析法原理对地热中高温热泵供暖系统进行了经济性分析。并与几种典型的供暖方式比较得出:在运行初期,该供暖方式年费用值较高;当系统运行5年后,其年费用除了高于燃煤锅炉外,均低于其他几种供暖方式。从经济性和环境影响方面综合考虑,认为地热中高温热泵供暖方式具有较好的利用前景。更多还原

【Abstract】 In light of energy shortages and environmental problems,this paper analyzed the heating system of geothermal middle/high-temperature heat pump with the principle of annual cost analysis combined with a case study.The following are the conclusions by comparing with some typical heating methods: the annual fee of this heating method is high in the early running;while it is lower than other heating methods except coal-fired boiler after the system running 5 years.The heating system with geothermal middle/high-temperature heat pump has a good application prospects in view of economic and environmental impacts.更多还原
