| Abstract: | The model of finned tube evaporator was constructed during frost condition and the simulation program of steady distribution parametre model was developed by Matlab.The evaporator was simulated by the program including interface program,the main program of calculation and the subprogram of thermodynamic properties calculation.The low temperature cold store was built.The curves of evaporator parameters changing with different refrigerant flow rate were achieved.The simulated and experimental data were compared.The results indicate that the simulation results and experimental data have a good accuracy and similar variety trend. |
| Keywords: | Frost condition Finned tube evaporator Steady simulation |
