To balance (S) a group of consumers in a fluid transport system in which each consumer is provided with a motorized control valve for regulating the flow through the consumer, characteristic data for the consumers is stored (S) which determines a valve position of the relevant control valve for target flows through one of the consumers in each case. A current total flow through the group of consumers is determined by means of a common flow sensor (S) and a balance factor (S) is defined on the basis of the current total flow and a sum of the desired target flows through the consumers. The consumers are dynamically balanced by setting (S) the valve settings for the corresponding control valves on the basis of the characteristic data and the balance factor.

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

For the purpose of balancing (S) a group of consumers in a fluid transport system in which each consumer is configured with a motorized regulating valve for the purpose of regulating the flow through the consumer, characteristic data for the consumer is saved (S) which determines a valve position of the corresponding regulating valve for the target throughput through each consumer. A momentary total throughput through the group of consumers is determined (S) by means of a common throughput sensor, and based on the momentary total throughput and a sum of the desired target throughputs through the consumers, a balancing factor is determined (S). By setting (S) the valve positions of the corresponding regulating valves based on the characteristic data and the balancing factor, a dynamic balancing of the consumers is carried out.

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

The present disclosure provides methods and systems for regulating the room temperature in a room or in a plurality of rooms, the room temperature can be regulated by regulating the mass flow of a heat-carrying fluid flowing through a heat exchanger according to a determined current room temperature. In accordance with some embodiments, a temperature sensor in the room can be dispensed that can determine the current room temperature, in each case the mass flow of the heat carrying fluid through the heat exchanger and the flow temperature prevailing at the input to the heat exchanger and the return temperature prevailing at the output of the heat exchanger are measured, and that a temperature assigned to the determined values of the mass flow, the flow temperature and the return temperature is output as the current room temperature and used for regulation.
