The aluminum models the multiple - unit tube the heat resistant scope - 40 - 95 鋁塑復合管的耐溫范圍- 40 - 95 。
The purpose of this study was to investigate the performance and thermodynamic mechanism of an engine exhaust - powered adsorption refrigerating unit tube using cacl2 as absorbent and nh3 as refrigerant 本文提出了一種氯化鈣-氨吸附制冷單元管的設計方法,并對其工作過程中的性能和熱動力學機理進行探索。
The working performances of the refrigerator were presented . it was concluded that the performances of unit tube were excellent , average refrigerating capacity was 66 . 4w and coefficient of performance was 0 . 2 通過對單元管實際運行試驗表明該單元管具有良好的制冷性能,平均制冷功率達66 . 4w ,性能系數(shù)達到0 . 2 。
An one - dimensional non - equilibrium mathematical model was established to describe the performances of unit adsorbent bed . finite difference forms of the equations were written in matlab . a conventional test bed for investigating the inner properties of cacl2 - nh3 unit tube was developed and the real data were used to test the model 在前人研究經(jīng)驗的基礎上,建立了單元管吸附床內(nèi)一維非平衡吸附條件下的傳熱傳質(zhì)數(shù)學模型,提出了該模型的數(shù)值求解方法,并給出了數(shù)值模擬算例。
