Abstract

A method for testing performance of a climate-controlled freight container comprises cooling down (S10) of a cargo compartment of the freight container to a predefined target temperature by use of a cooling system, comprising at least two cooling modules. A temperature distribution within the cargo compartment is equalized (S20) during a predetermined equalizing period. An individual cooling module test (S30) is performed for all the at least two cooling modules, one at a time. The individual cooling module test in turn comprises controlling (S32) of the cargo compartment to have a constant temperature during a predetermined period by operating a single cooling module and measuring (S34) a power consumption of the single cooling module during the predetermined period.
