Mathematical Model of Displacement Compressor

Mathematical model,describing the changing laws of discharge gas velocity and gas pressure for displacement compressor in discharge process is established.

建立了通用于容积式压缩机排气过程中描述排气口气速和工作腔内气体压力变化的数学模型,以往复压缩机为例,应用龙格-库塔法对其进行数值求解,得到了排气口气速和工作腔内气体压力随主轴转角的变化规律。

The two aspects are comprehensively taken into consideration in this paper,and are used as the evidence of method adopted in the performance experiment of positive displacement refrigerant compressor condensing units.

从热力学角度考虑能量使用的完善性和合理性(效率),从经济学角度考虑最小初投资和运行费用,综合考虑以上两个因素,并将此作为容积式压缩冷凝机组性能试验方法选择的依据。
