| Notes | 11-2182/TB A generalized algorithm called ALG-I as well as a companion algorithm called ALG-II,for simulation of variable refrigerant flow（VRF） systems were proposed.Firstly,the principles and methods to find the criteria of iterative calculation and choose the variables of iterative calculation were introduced.Then,the standard algorithm was organized by some proper combination between the iterative variables and the iterative criteria,and the critical steps of the algorithm were described in detail.ALG-I and ALG-II have very similar characteristics except time-consuming.Simulation results revealed that the models established are feasible and effective to simulate the VRF systems with different number of evaporators,which indicates the proposed system algorithms are generic and evaporator-number independent.For the VRF system with only one evaporator,the much larger time consuming of the ALG-I weakened the potential for control analysis applications,while for the multi-evaporator VRF system,the ALG-I has adva |
