To improve the performance of ashp, an improved ashp system is presented. different from the original system, the new one can control the refrigerant flow rate by the sub - cooling of condenser and adjust the sup - heating of the compressor inlet vapor by the heater in accumulator. the simulation shows the new system not only has better dynamic characteristic of frost and defrost of ashp, but also has higher coefficient of performance
為改善空氣源熱泵機組的結霜除霜動態性能,提出了一種利用冷凝器過冷度來調節製冷劑流量,在氣液分離器里增加電熱裝置保持壓縮機進口過熱度的改進型系統,結果表明這種改進型系統不但可以改善系統的運行性能,同時能改善系統運行的經濟性,為機組的技術升級和產品更新提供了一個新的途徑。Measurements were made of system pressure, mass flow rate of steam, air, and cooling water, temperatures of condensing flow and cooling flow, and the water level of boiler. the major phenomena observed in the present experiment are similar to those by other investigators. the mass flow rate of steam, the system pressure and air content are the most important factors affecting steam condensation
實驗結果表明,維持二次側冷卻水流量不變,無論對于純凈蒸汽還是含有空氣的蒸汽冷凝,隨著蒸汽發生器加熱功率的增大(即蒸汽流量增大) ,有效冷凝段長度將加長;當蒸汽中含有少量空氣,有效冷凝段長度也會明顯加長;提高系統壓力,有效冷凝段長度將縮短。With the increase in production load, there is heavy liquid entrainment from the rectification column, resulting in a rise in urea content in the low - pressure ammonium carbamate solution, bringing about the cold crystallization of the low - pressure carbamate, cavitation erosion of the carbamate pump, and a decrease in decomposition of the carbamate in the rectification column, thereby impairing safety in production
摘要生產負荷提高后,精餾塔帶液嚴重,使低壓甲銨液中的尿素含量增加,引起低壓甲按冷凝器結晶、甲銨泵氣性、精餾塔甲按分解率下降等現象,嚴重影響安全生產。The condensation heat - exchange characteristic of a separate - type heat - pipe was studied on a 1 : 1 model. the heat pipe is heated by electricity, and working fluid is distilled water, and it is cooled by air. the experimental results show that, ( 1 ) when charging liquid ratio is 45 %, condensation heat - exchange coefficient reaches to maxium ; ( 2 ) when there is not non - condensing gas, the coeffcient decreases a little with the increase of vapour pressure, and it decreases by 9. 5 % when the pressure increases from 0. 16mpa to 0. 36mpa ; ( 3 ) when there is non - condensing gas, the coefficient decreases a little, but when the gas is discharged by an exhaust value, it can be improved, when the volume content of the gas is 2. 5 %, it can increased by 22 % ; ( 4 ) the effect of the non - condensing gas on the coefficient decreases with the increase of the pressure, and when the volume content of the gas is 5 % and the pressure increases from 0. 16mpa to 0. 36mpa, the coefficient increases by 6 %. the relative curves are given between condensation heat - exchange coefficient and air flowrate, charging liquid ratio and vapour pressure
