    摘要:

    在北京地區(qū)一棟玻璃連棟溫室 (756m2) 中采用地下水式地源熱泵（ground source heat pump, 簡稱GSHP）技術(shù)進(jìn)行了冬季供暖試驗，并結(jié)合GSHP技術(shù)的供熱特點構(gòu)建了基于供熱末端空氣焓差法的供熱量計算模型以及供熱系統(tǒng)性能分析方法。根據(jù)供暖期北京地區(qū)能源價格水平，對比當(dāng)前廣泛使用的燃煤供暖系統(tǒng)和天然氣供暖系統(tǒng)，系統(tǒng)地評價了GSHP技術(shù)的碳排放（溫室氣體排放水平）和供暖經(jīng)濟(jì)性。GSHP供暖成本低于同期燃?xì)夤┡哂谌济汗┡?。同時，GSHPs的CO2氣體排放量低于燃煤供暖，但高于燃?xì)夤┡?/p>

    Abstract:

    The heating test was conducted in a glass-covering multi-span greenhouse (756m2) 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.
