| 摘 要： | 为了预测涡旋式水源热泵系统变结构和变工况稳态性能,建立了稳态涡旋式热泵系统仿真模型.其中涡旋式压缩机模型考虑了吸、排气换热对工质流量和排气温度的影响以及流量、排气温度和输入功率三者的耦合关系；通过增加电子膨胀阀开度对蒸发器出口过热度的控制模型,反映了过热度对膨胀阀流量的影响.系统算法综合了顺序模块法和连续迭代法,改善了迭代收敛性,且易于实现部件模型的模块化.与实验结果对比表明:模型预测值与实验值的误差小于4.4％.

| Abstract: | To predict the steady performance of scroll water source heat pumps with different configuration and working conditions,a steady systematic model for scroll water source heat pump is established.In modeling the compressor,the effect of suction heating on mass flow and the effect of discharge heat exchange on discharge temperature as well as coupling relationship between mass flow,discharge temperature and input power are considered.The effect of the superheat of evaporator on the mass flow through the elect... |
