【摘要】：針對北方寒冷地區(qū)冬季和夏季冷熱需求不平衡的現(xiàn)象，本文以天津市一套太陽能-地源熱泵聯(lián)合供暖空調(diào)系統(tǒng)為研究對象，并與兩套對比方案系統(tǒng)相比較，開展了空調(diào)系統(tǒng)全壽命周期能耗評價(jià)研究。 本文詳細(xì)介紹了太陽能-地源熱泵空調(diào)系統(tǒng)的組成設(shè)備和監(jiān)測儀器，根據(jù)該系統(tǒng)一年半期間的實(shí)際運(yùn)行數(shù)據(jù)，從集熱效率、儲熱率、取熱率、地溫變化等方面，對太陽能跨季節(jié)儲熱系統(tǒng)的特性進(jìn)行了評價(jià)，又分別對地源熱泵（GSHP）系統(tǒng)和太陽能輔助地源熱泵（SAGSHP）系統(tǒng)的制冷/供暖性能系數(shù)（COP）及各設(shè)備的能耗進(jìn)行了分析。根據(jù)實(shí)際采暖季的供熱量數(shù)據(jù)計(jì)算出建筑的耗熱量指標(biāo)為22.97W/m2，并分析了耗熱量指標(biāo)偏高的原因主要是室內(nèi)溫度過高和不注意行為節(jié)能而造成的。但從系統(tǒng)的耗能（只有電耗）折算到發(fā)電煤耗來計(jì)算，其耗煤量指標(biāo)為6.28kg/m2，具有顯著節(jié)能優(yōu)勢。 根據(jù)全壽命周期評價(jià)理論，采用實(shí)際調(diào)研、資料查閱等方法，得出了空調(diào)系統(tǒng)的物化能耗清單，系統(tǒng)設(shè)備生產(chǎn)、建設(shè)等過程中對一次能源（煤、油和天然氣）的消耗量清單。 用TRNSYS模擬軟件創(chuàng)建了太陽能-地源熱泵空調(diào)系統(tǒng)及兩套對比系統(tǒng)（冷水機(jī)組-燃?xì)忮仩t系統(tǒng)、地源熱泵-電輔助加熱系統(tǒng)）的仿真模型，在完成模型的驗(yàn)證后，預(yù)測了三種系統(tǒng)的壽命期內(nèi)（30年）耗能總量。 最后，基于全壽命周期能耗評價(jià)理論，，對太陽能-地源熱泵空調(diào)系統(tǒng)及兩個(gè)對比方案的全壽命周期能耗和資源耗竭系數(shù)進(jìn)行了對比評價(jià)，結(jié)果發(fā)現(xiàn)：太陽能-地源熱泵空調(diào)系統(tǒng)比冷水機(jī)組-燃?xì)忮仩t系統(tǒng)和地源熱泵-電輔助加熱系統(tǒng)在全壽命周期內(nèi)能耗分別低14.35%和15.40%，物化能占整個(gè)壽命周期能耗的比例分別為：14.4%、10.7%和10.9%；三種系統(tǒng)的全壽命周期資源耗竭系數(shù)比值為1：2.69：1.12。從全壽命周期能耗的角度對實(shí)際太陽能-地源熱泵系統(tǒng)給予了合理評價(jià)，證明了該空調(diào)系統(tǒng)的節(jié)能性，為太陽能-地源熱泵組合空調(diào)系統(tǒng)的推廣應(yīng)用提供了評價(jià)依據(jù)。
[Abstract]:In view of the imbalance of cold and heat demand in winter and summer in the cold region of northern China, this paper takes a solar and ground source heat pump combined heating and air conditioning system in Tianjin as the research object, and compares it with two sets of contrast schemes. The energy consumption evaluation of the whole life cycle of air conditioning system is carried out. This paper introduces the composition equipment and monitoring instrument of solar-ground source heat pump air conditioning system in detail. According to the actual operation data of the system during one and a half year, the heat collection efficiency, heat storage rate, heat recovery rate, ground temperature change and so on are discussed. The characteristics of solar energy transseasonal heat storage system are evaluated, and the refrigeration / heating performance coefficient (COP) of ground source heat pump (GSHP) system and solar assisted ground source heat pump (SAGSHP) system are analyzed respectively, and the energy consumption of each equipment is also analyzed. According to the heat supply data of actual heating season, the heat consumption index of buildings is 22.97 W / m ~ 2. It is analyzed that the high heat consumption index is mainly caused by high indoor temperature and energy saving by neglecting behavior. However, from the energy consumption of the system (only electricity consumption) to the coal consumption of power generation, the coal consumption index is 6.28 kg / m ~ (2), which has a remarkable advantage of energy saving. According to the theory of life cycle evaluation, the list of physical and chemical energy consumption of air conditioning system, the consumption list of primary energy (coal, oil and natural gas) in the process of production and construction of air conditioning system are obtained by means of actual investigation and data reference. The simulation model of solar-ground source heat pump air conditioning system and two contrast systems (chiller-gas boiler system, ground-source heat pump electric auxiliary heating system) was established by using TRNSYS simulation software. The total energy consumption over the lifetime (30 years) of the three systems is predicted. Finally, based on the whole life cycle energy consumption evaluation theory, the whole life cycle energy consumption and resource depletion coefficient of solar-ground source heat pump air conditioning system and two comparison schemes are compared and evaluated. The results show that the energy consumption of solar-ground source heat pump air conditioning system is 14.35% and 15.40% lower than that of chiller gas-fired boiler system and ground-source heat pump electric auxiliary heating system in the whole life cycle, respectively. The physical and chemical energy accounts for the energy consumption of the whole life cycle. The ratio is 10.7% and 10.9%, respectively. The ratio of the life-cycle resource depletion coefficient of the three systems is 1: 2.69: 1.12. A reasonable evaluation of the actual solar-ground source heat pump system is given from the point of view of life-cycle energy consumption, which proves the energy saving of the air-conditioning system, and provides an evaluation basis for the popularization and application of the solar-ground source heat pump combined air-conditioning system.
