Abstract
The invention concerns a new control unit for pumps (3) for heat- and chill-transferring media, which records all parameters for the regulation of the pump in or close to the pump independently from the distance to the heat source (2) or cooling source.Thus the often complex wiring between heat source (2) and heat sink (1) and/or cooling source and cooling sink is omitted. The control unit may be installed directly on the pump (3) or integrated in the pump consequently.The controller recognizes self learning due to the evaluation of the operating conditions typical system parameters, so that the positioning of the system-dependent temperature differences for control processes is not necessary and can be omitted.The construction of the pump (3), integrated controller (4) and sensors (7, 8, 9, 10) close-up range enables a manufacturing of completely pumps prepared for the operation including a controller in extremely compact construction.
