| 摘 要： | 一拖三VRV空调系统由于各蒸发器之间参数的相互影响，使得其运行特性十分复杂。该文采用分布参数法，引用空泡系数，建立起以变频压缩机、三电子膨胀阀、三蒸发器为一体的系统的热力学仿真模型；对系统进行仿真研究，得出不同工况下系统的运行特性。仿真结果表明在一拖三VRV空调系统中进行吸气压力控制的必要性与优越性，为系统的控制方法的制定以及系统的优化设计奠定基础。

| Abstract: | The performance of triple-evaporator VRV air conditioner is very complex because of the interaction of respective evaporators. A distributed-parameter model based on two-phase flow theory in triple-evaporator VRV air conditioner is established in this paper. The simulations using this model have been conducted and the performance of system has been analyzed. According to the analysis the necessity and advantage of the control of suction pressure is presented here. The result of this paper should help the establishment of control strategies of such an air conditioning system. |
