Abstract:
1. A method for correcting a first media flow of a heat or coldness transport medium in a refrigeration system, the method comprising the steps of: causing the first media flow to move through a heat exchanger in which a heat transfer between the first media flow and a second media flow of a heating or cooling agent occurs; determining the second media flow as a linear function proportional to a pressure differential across and the opening degree of an expansion valve; determining the change in the enthalpy of the second media flow or a value derived therefrom; determining a change in the first media flow from the change in the enthalpy of the second media flow or from the value derived therefrom; and correcting the first media flow flowing through the heat exchanger, based on the determined change in the first media flow.
