Abstract:
A method of analyzing a refrigeration system (1) comprising at least one compressor (4), at least one condenser (5) and at least two refrigeration entities (2), each comprising at least one evaporator (9). Based on information relating to the gas production by the evaporators (9) it is determined whether or not two or more evaporators (9) are running in a synchronized manner, i.e. are switching between an active and an inactive state at least substantially simultaneously. In case two or more evaporators (9) are running in a synchronized manner, the refrigeration system (1) may be controlled in order to desynchronize the evaporators (9). This may, e.g., be done by changing a cut-in temperature and/or a cut-out temperature for one of the corresponding refrigeration entities (2). Synchronization causes undesired variations in the suction pressure, and preventing synchronization therefore results in a more appropriate control of the refrigeration system (1). Reduces wear on the compressors (4). Furthermore, a method of applying settings to a plurality of refrigeration entities (2) in such a way that synchronization is prevented or at least reduced considerably.
