Abstract: Provided is a method (300) of determining a loss of charge of refrigerant in a refrigeration system(100). The method (300) comprises determining at least one performance characteristic of the refrigeration system (100). The at least one performance characteristic comprises a mass flow rate of the refrigerant in the refrigeration system (100). The method (300) further comprises, when one or more predetermined criteria are met on the basis of the performance characteristic, determining a loss of charge in the refrigeration system (100).
