Abstract:
1. A method of analysing a refrigeration system comprising at least one compressor, at least one condenser, at least one control unit and at least two refrigeration entities, each having a separate refrigeration volume, and each comprising at least one evaporator controlled by the control unit, each evaporator being adapted to be in an active state in which a flow of refrigerant is allowed to pass across an evaporating surface, and in an inactive state in which such a flow is prevented, the method comprising the steps of: obtaining information at the control unit relating to the gas production provided by the evaporators as a function of time, wherein the information relating to the gas production provided by the evaporators comprises information relating to the number of active evaporators as a function of time, analysing the obtained information within the control unit, the analyzing step comprising obtaining a representative of the variance of the function of time, based on the analysing step, determining whether or not two or more of the evaporators are running in a synchronized manner, wherein it is determined that at least two evaporators are running in a synchronized manner if the representative of the variance exceeds a predefined threshold value, sending at least one control signal when it is determined that two or more evaporators are running in a synchronized manner, and adjusting at least one run parameter, wherein the adjusting step is selected from the group consisting of:
