1. the coefficient of an electric expansion valve model determines method, it is characterised in that including:

  • The test data of experiment utilizing electric expansion valve is calculated the pressure drop of the electric expansion valve model pre-buildCoefficient;

    Described electric expansion valve mode input pressure drop to be measured after calculating pressure-drop coefficient;

    It is calculated the flow that described pressure drop to be measured is corresponding by described electric expansion valve modeling;

    Judge that the flow pressure drop to be measured with described in experiment test simulating the pressure drop described to be measured obtained corresponding is correspondingWhether the error of flow exceedes preset range;

    When described error is less than described preset range, using the pressure-drop coefficient that calculates as described electronic expansionThe pressure-drop coefficient of valve model.
