Varmevekslersystem og fremgangsmåde til detektion af en relokering af en temperatursensor i et varmevekslersystem

The present invention relates to a heat exchanger system (1) comprising a heat exchanger (2) and a temperature sensor arrangement. Furthermore, the invention relates to a method for detecting a relocation of a temperature sensor (9, 10) in a heat exchanger system (1). According to the invention, the heat exchanger system (1) comprises one or more electronic relocation detection units (8) being adapted to detect whether one or more temperature sensors (9, 10) of the temperature sensor arrangement are relocated relative to the heat exchanger (2). This allows a good setting for a fluid flow through the heat exchanger which is adequately corresponding to a room temperature as tempering with the temperature sensor arrangement can easily be noticed and maintenance can be initiated accordingly.
