AN ELECTRONIC CONVERTER UNIT FOR RETROFITTING TO AN EXTERNAL PART OF A HOUSING OF A PUMP UNIT

A method of balancing a heating system with a flow system, including a supply flow line (60) and a return flow line (70), a heat source (55) and a pump (10) hydraulic lines (L1-Ln), some having a heating element (H1-Hn) with a balancing valve (V1-Vn). The method includes: carrying out one or more me...

Beschreibung
Zusammenfassung:	A method of balancing a heating system with a flow system, including a supply flow line (60) and a return flow line (70), a heat source (55) and a pump (10) hydraulic lines (L1-Ln), some having a heating element (H1-Hn) with a balancing valve (V1-Vn). The method includes: carrying out one or more measurements by opening one hydraulic line only and determining a flow rate through the pump and a pressure difference across the pump, establishing a hydraulic model based on the determined flow rate and pressure difference from at least two measurements from step, and at least one additional measurement for at least two hydraulic lines, specifying a desired flow rate for each of the hydraulic lines, and adjusting one or more of the dedicated balancing valves in order to meet the desired flow rate for each of the hydraulic lines by using the hydraulic model.
