With the in - built drip irrigation belt and thin wall chip irrigation belt taken as examples , the flow rate distribution and hydraulic losses of drippers along capillary tubes at different inlet pressures were measured under the conditions of horizontal slope and slope gradients of 0 . 5 % and 1 % , then the uniformity of capillary tubes was calculated at different slope gradients and pressures in consideration of the manufacture deviation of drippers 摘要以內鑲式滴灌帶和薄壁滴灌帶為研究對象,測定了平坡、 0 . 5 %坡度和1 %坡度時,不同入口壓力下滴頭沿毛管的流量分布和水力損失,并結合滴頭的制造偏差,計算得出不同坡度和壓力條件下滴灌毛管的均勻度。

An analysis about how the frequency affects refrigeration system performance has been discussed particularly . in the end , the effect of refrigerant charge and capillary tube length on refrigeration system performance is discussed systematically when the frequency is varied 最后,計算并分析了制冷劑充灌量和毛細管長度在頻率改變后對制冷系統性能的影響,提出了5hp變頻空調器制冷劑充灌量和毛細管長度的確定原則。

By making use of the simulation results , a principle about how to confirm the refrigeration charge and capillary tube length for the 5hp inverter controlled air - conditioner has been put forward . the results are of direct interests to reduce time - period of product developments 所得結論對5hp變頻空調器制冷劑充灌量和毛細管長度的選擇具有一定的指導意義,對縮短新產品研制周期亦具有一定的參考價值。

The model includes the select of various refrigerants and various parameters . the paper also numerically simulates and analyzes the flow of refrigerants , namely r12 and r134a respectively in the adiabatic capillary tube 此外,本文還完善了基于visualc + + 6 . 0的均相流絕熱毛細管數值模擬,軟件提供了工質和參數選擇,并數值分析了兩種制冷劑r12 、 r134a在毛細管內的流動特性。

The study indicates that , the slippage effect is a combined result of gas molecule slip on capillary wall and gas molecular diffusion inside capillary tube , and also a result of combination of concentration and pressure fields 研究認為,氣體滑脫效應是毛細管壁處氣體分子滑流和毛細管內部氣體分子擴散的綜合效應,是濃度場和壓力場作用疊加的結果。

Experimental result shows that the layout of the capillary tubes along the down slope at a rational gradient and increase of the inlet pressure are helpful to improve the uniformity of capillary tubes 試驗結果表明,將毛管鋪設成恰當的順流下坡坡度或提高入口壓力均可提高毛管的滴灌均勻度。
