| 摘 要： | 利用TRNSYS软件平台建立了基于控制分析的变流量空调系统仿真器，并建立了R410a物性的显式快速计算模型。在该仿真平台上进行吸气过热度控制仿真实验时，发现制冷剂物性计算的连续性和复现性会影响控制仿真结果，因此对制冷剂物性计算模型做了合适的的修正，保证了仿真计算的连续性和良好的复现性。结果表明：经过修正的R410a物性计算模型仍能保持较高精度，并可以有效改善吸气过热度控制的稳定性。

| Abstract: | The simulation platform of the variable flow air conditioning system is setup based on TRNSYS software platform. To accelerate simulation speed to ensure it can be used for control analysis, the fast and explicit expression models for R410a thermodynamic properties are corrected to ensure their repeatability in calculation of changing phase. The results show that corrected model still maintains high accuracy and the stability of control of superheating in suction can be improved significantly. |
