A method for controlling a flow of fluid through a heat exchanger (3) in which heat is transferred from a first fluid (F HTF ) to a second fluid (F MS ). A flow regulator (13, 14) is arranged to regulate a flow of the second fluid (F MS ) passed through the heat exchanger (3), the method comprising: determining (102) a first difference ( HAT ) between an inlet temperature ( T hot in ) of the first fluid (F HTF ) and an outlet temperature ( T cold out ) of the second fluid (F MS ); determining (102) a second difference ( CAT ) between an outlet temperature ( T hot out ) of the first fluid (F HTF ) and an inlet temperature ( T cold in ) of the second fluid (F MS ); determine (104) first and second error values ( µ HAT , µ CAT ) by calculating differences between two predetermined values ( HAT target , CAT target ) and the respective of the first and second differences ( HAT, CAT ) ; and controlling (116) the flow regulator (13, 14) in dependence of the error values ( µ HAT , µ CAT ). |
