摘要:
以一次泵变流量水系统为研究对象，实验研究了无压差控制和定压差控制下变流量空调水系统的水力稳定性.建立了相应的TRNSYS仿真模型，仿真研究了变压差控制下水系统的水力稳定性.结果表明：对于提高系统水力稳定性和节能效益，变压差控制策略效果显著.变压差控制下管网的水力失调系数为0.072，较无压差控制时减小了0.442；关闭任一支路阀门，变压差控制下冷冻水泵节能可达到27.1%.
Abstract:
Taking the primary variable displacement water system as the research object, the hydraulic stability of the variable flow air conditioning system under none-pressure control and constant pressure difference control was experimentally studied. The corresponding TRNSYS simulation model was established and the hydraulic stability of the water system under variable pressure difference control was simulated. The results show that the effect of variable pressure differential control strategy is significant for improving the hydraulic stability and energy saving efficiency of the system. The hydraulic imbalance coefficient of the pipe network under variable pressure difference control is 0.072, which is 0.442 when compared with no pressure difference control. When the valve of any branch is closed, the energy saving of the frozen water pump under variable pressure difference control can reach 27.1%.
