| Notes | Fu Sijie Jin Xinqiao Zhu Yonghua Du Zhimin Fan Bo （ Institute of Refrigeration and Cryogenics, Shanghai Jiao Tong University, Shanghai ,200240, China） 11-2182/TB VRF air-conditioning system ; simulation of control ; corrected model of thermodynamic property 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 accu- racy and the stability of control of superheating in suction can be improved significantly. |
