| 摘 要： | 在北京地区一栋玻璃连栋温室(756 m2)中采用地下水式地源热泵(ground source heat pump,简称GSHP)技术进行了冬季供暖试验,并结合GSHP技术的供热特点构建了基于供热末端空气焓差法的供热量计算模型以及供热系统性能分析方法。根据供暖期北京地区能源价格水平,对比当前广泛使用的燃煤供暖系统和天然气供暖系统,系统地评价了GSHP技术的碳排放(温室气体排放水平)和供暖经济性。GSHP供暖成本低于同期燃气供暖,但高于燃煤供暖。同时,GSHPs的CO2气体排放量低于燃煤供暖,但高于燃气供暖。

| Abstract: | The heating test was conducted in a glass-covering multi-span greenhouse(756 m2) with groundwater-style GSHP technology.The heat quantity estimating models based on air enthalpy difference method(AEDM) were developed according to the heating characteristics of GSHP.The economical performance and carbon footprint(greenhouse gas emission level) of the GSHP was analyzed and compared with currently widely used coal fired heating system(CFHs)and natural gas fired heating system(GFHs) based on investigated various energy sources price during heating tests.According to the compared results,the GSHPs heating cost is higher than CFHs,but lower than GFHs.Meanwhile,GSHPs CO2 emission during heating is higher than GFHs,but lower than CFHs. |
