Abstract

Flow control module and method for controlling the flow in a hydronic system The present disclosure is directed to a flow contro l module (39) for con- trolling one or more pumps in a hydronic system (1) , wherein the hy- 5 dronic system (1) comprises - a primary side (3) with a first port (21) in flui d connection with an output (23) of at least one source element (7), a s econd port (27) in fluid connection with an input (29) of the at least one source element (7), and at least one controllable primary side flo w actuator (9) for 10 providing a primary side flow (q 1), - a secondary side (5) with a third port (31) in fl uid connection with an input (33) of at least one load element (11), a fourth port (35) in fluid connection with an output (37) of the at least one load element (11), and at least one controllable secondary side flow a ctuator (13) for 15 providing a secondary side flow (q 2), and - an intermediary transfer element (17) between the primary side (3) and the secondary side (5), wherein the intermediar y transfer element (17) is in fluid connection with the first port (21 ), the second port (27), the third port (31) and the fourth port (35). The f low control module (39) 20 is configured to adapt the thermal power transfer o f the intermediary transfer element (17) by controlling the primary si de flow (q 1) by means of the at least one controllable primary side flow actuator (9) and/or the secondary side flow (q 2) by means of the at least one controllable secondary side flow actuator (13) in a continuous o r regularly closed- 25 loop manner based on minimising a signed deviation value ( ∆∆ v) being correlated with the thermal power transfer of the i ntermediary transfer element (17).
