【摘要】：中國能源利用率水平低下，我國產(chǎn)生單位GDP所消耗的能源量居高不下，每萬美元GDP能耗是德國的4~5倍，是日本的8倍左右。地源熱泵作為二十一世紀的可再生能源，受到了高度的重視，建筑能耗占社會終端能耗的很大比例，建筑節(jié)能是全社會“節(jié)能減排”的重要組成部分。 地源熱泵系統(tǒng)有多種形式，包括土壤源熱泵，地表水源熱泵，地下水源熱泵，地表污水源熱泵等等，截至2011年，，我國地源熱泵總應(yīng)用面積達到2.4億平方米，但是實際應(yīng)用情況存在諸多問題，如許多理論正在研究階段，無法應(yīng)用于實際項目中等等。 本文介紹了目前國內(nèi)外地源熱泵評價方法與計算方法的發(fā)展情況，分析了地源熱泵系統(tǒng)的應(yīng)用特點，對地源熱泵系統(tǒng)中土壤源熱泵系統(tǒng)的實際運行能效水平進行分析，通過對實際工況下地源熱泵機組與系統(tǒng)的實測與分析，找出影響系統(tǒng)與機組能效的關(guān)鍵運行參數(shù)，并得出他們之間的函數(shù)關(guān)系，并通過TRNSYS對地源熱泵典型工況進行建模，得出模型下的能效值，對能效水平的模型進行驗證。為下一步實際工程中土壤源熱泵系統(tǒng)評價指標的得出打下基礎(chǔ)，但是模型仍然需要進一步優(yōu)化，基礎(chǔ)數(shù)據(jù)也應(yīng)隨著項目數(shù)量的不斷增多而豐富起來，提高模型的精確度，進而更加準確的反應(yīng)土壤源熱泵系統(tǒng)實際運行情況。
[Abstract]:The level of energy utilization in China is low and the energy consumption per unit GDP of China remains high. The energy consumption per 10 thousand US dollars of GDP is 4 times of that of Germany. Ground source heat pump (GSHP), as a renewable energy source in 21th century, has been highly valued, and the building energy consumption accounts for a large proportion of the social terminal energy consumption. Building energy saving is an important part of the whole society. Ground source heat pump system has many forms, including ground source heat pump, surface water source heat pump, ground water source heat pump, surface sewage source heat pump and so on, until 2011. The total application area of ground-source heat pump in China is up to 240 million square meters, but there are many problems in the practical application, such as many theories are in the research stage and can not be applied to the actual project and so on. This paper introduces the development of evaluation methods and calculation methods of ground-source heat pump at home and abroad, and analyzes the application characteristics of ground-source heat pump system. The actual operating energy efficiency level of ground source heat pump system in ground source heat pump system is analyzed, and the actual measurement and analysis of ground source heat pump unit and system under actual operating conditions are carried out. Find out the key operating parameters which affect the energy efficiency of the system and the unit, and get the functional relationship between them, and through TRNSYS to model the typical operating conditions of ground-source heat pump, get the energy efficiency value under the model. The model of energy efficiency level is verified, which lays the foundation for the evaluation index of ground-source heat pump system in the next practical project, but the model still needs to be further optimized. The basic data should be enriched with the increase of the number of projects to improve the accuracy of the model and then reflect the actual operation of the GSHP system more accurately.
