Résumé :
|
The mathematical modelling of a refrigeration system involves developing of equations which predict the movement of refrigerant in the system and the change of state of refrigerant in the system components with time. Development of a computer program which is to be used as a design tool requires that the computational time be a minimum for the computer program to be economical. This was achieved for the complex physical phenomema associated with the refrigeration system by combining basic engineering principles with empirical parameters for system intricacies like heat transfer coefficients, oil transportation, oil-refrigerant foaming which need to be evaluated experimentally.The developed mathematical model was applied to an existing unitary room air conditioner. The general trend of the predicted results agrees with how the actual system would respond, as experienced by the sponsor's engineering staff and other engineers knowledgeable in this field.
