For thoroughly know the energy saving effect of gehp , the thermodynamics analysis is processed with the first law of thermodynamics , exergy theory , energy grade theory and thermoeconomic method 為了深入了解燃氣機熱泵的節(jié)能效果,本文進行了熱力學第一定律、 (火用)分析、能級分析和熱經(jīng)濟學分析。
Based on numerous papers on automatic seedling classification ( asc ) , the seedling grading theory , traditional grading methods , the background and the proceeding of asc techniques are described 本文在對目前苗木自動分級文獻理解和綜合的基礎(chǔ)上,首先通過對苗木分級技術(shù)和分級理論的研究,揭示了自動分級技術(shù)的發(fā)展背景和理論基礎(chǔ)。
Because the improvement of coefficient of performance of the gehp mainly due to the use of waste heat from surroundings , we suggest that we should use energy grade theory to evaluate the performance of heat pump 由于能級平衡理論分析考慮了(火無)的作用,而熱泵供暖時其性能系數(shù)的提高主要是利用了環(huán)境熱量,所以建議采用能級平衡理論來分析評價熱泵的性能。
The ecology investigate viewpoint , life cycle assessment and energy redundancy degree will develop the theory of cogeneration , while the exergy analysis , energy grade theory and thermo - economic method also enrich the evaluation method of industrial ecology 工業(yè)生態(tài)學的生態(tài)學研究視角、生命周期評價方法和能量冗余性可以拓展總能系統(tǒng)的理論。而總能系統(tǒng)的(火用)分析、能級平衡理論和熱經(jīng)濟學分析方法可以豐富工業(yè)生態(tài)學評價方法。
