Method and devices for equalizing a group of consumers in a fluid transport system

A device (1) for balancing a group of consumers (V1, V2, V3, Vi) in a fluid transport system (5, 5′) in which each consumer (V1, V2, V3, Vi) is configured with a motorized regulating valve (V11, V22, V33, Vii) for the purpose of regulating the flow through the consumer (V1, V2, V3, Vi), and in which a common flow sensor (4) is included for the purpose of measuring a total throughput through the group of consumers (V1, V2, V3, Vi), characterized by:

• a characteristic data module (11) which is designed for saving characteristic data for each of the consumers (V1, V2, V3, Vi), said characteristic data determining a valve position (Hi) of the corresponding regulating valve (V11, V22, V33, Vii) for each of the target throughputs (Fi) through each of the consumers (V1, V2, V3, Vi), and
• a balancing module (12) which is designed to determine the momentary total throughput through the group of consumers (V1, V2, V3, Vi) by means of the flow sensor (4), to determine a balancing factor based on the momentary total throughput and a sum of the desired target throughputs through the consumers (V1, V2, V3, Vi), and to carry out a dynamic balancing of the consumers (V1, V2, V3, Vi) by setting the valve positions (Hi) of the corresponding regulating valves (V11, V22, V33, Vii) based on the characteristic data and the balancing factor.
