Shenzhen kedesun also can provide best solution of comfortable environment control and system energy saving 深圳科迪遜科技有限公司提供舒適的環(huán)境控制及系統(tǒng)節(jié)能方案!
The thermal comfort control was applied to meet the need of comfortable feeling of people and meet the demands of system energy saving 摘要采用熱舒適控制不僅能滿足人體的舒適感,而且還能滿足系統(tǒng)節(jié)能的需要。
However , this will increase the system energy consumption . the gap is becoming wider between high performance and limited capacity of battery . low power design is an effective approach to solve above problem 為解決上述矛盾,在滿足用戶性能要求的前提下,降低系統(tǒng)功耗,盡量延長系統(tǒng)的使用時間成為嵌入式系統(tǒng)設(shè)計目標之一。
In this paper , aimed at dalian youhao mansion , theoretic analysis and spot testing studing about the adopt possibility . system energy - saving design and operating energy - using of vrv heat pump air condition system are discussed 本文針對友好大廈項目,就vrv熱泵空調(diào)系統(tǒng)冬季采暖的可行性、系統(tǒng)節(jié)能設(shè)計、運行能耗等方面進行了理論分析及現(xiàn)場測試研究。
Analysis on the system energy flow characteristic indicated the longer the distance between farmer and his plot is , the smaller the energy input is . therefore , the yielding economic energies per 666 . 7m2 are lower . the energy flow efficiency of system is depressed because of the separation and fragmentation of arable land 同時系統(tǒng)的能流特征分析表明,農(nóng)戶到地塊的距離越長,投能就越少,畝產(chǎn)經(jīng)濟能就越低,土地的破碎與分散降低系統(tǒng)能流效率。
In the paper , with system energy balance method and heat conductive equations , on tne basis of short time heat transfer modeling established the long time modeling , considering heat interference in thermal well group . this paper used the finit element method for element division and computer analysis , and provided the operation temperature figure . acquired computation values agreed well with experimental results , the most difference between them was 5 . 13 % 本文采用系統(tǒng)能量平衡結(jié)合熱傳導(dǎo)方程,在淺埋套管式換熱器短期傳熱模型基礎(chǔ)上建立了長期傳熱模型,并考慮了管群熱干擾對模型的影響。并運用有限單元法軟件編程進行離散和計算機分析,得出模擬溫度場,其模擬值與實測的均值基本相符,兩者最大誤差小于5 . 13 % ,表明該模型具有一定的合理性和實用意義。
We obtained the system energy and binding energy of ground and some low - lying excited states by solving the equation hnm - e = 0 . different from the variational method ' s result closely depending on the form of the trial wave function , our result has high accuracy as long as the matrix we used is big enough 與變分法的結(jié)果對選取的變分波函數(shù)依賴性很大不同,從理論上來沁j北師他人學礬卜畢業(yè)論義陳紅葉說,只要我們的矩陣展開的足夠大,我們的結(jié)果就能保證足夠高的計算精度。
