Method for regulating the volume flow of a heating and/or cooling medium via a space heat exchanger of a heating or cooling plant

Abstract

A method for regulating the volumetric flow of a heating and / or cooling medium via a space heat exchanger of a heating or cooling plant, in which the flow is controlled by an adjustable and / or fixable restriction of a corresponding space heat exchanger valve Target bifurcation that regulates the process and return temperatures of the individual space heat exchangers, defining space heat exchangers with different priorities, where, based on device-specific target bifurcation, smaller ones are allowed for high priority space heat exchangers The target fork and the larger target fork are guaranteed for low-priority space heat exchangers. When a high-priority space heat exchanger is operated with a smaller branch, the volume flow through at least one low-priority space heat exchanger with a larger branch is changed in such a way that the flow from the heating system The mixing of the return medium of all space heat exchangers enables an optimal adjustment of the return temperature for the heating device of the heating system.

Description

technical field [0001] The invention relates to a method for regulating the volume flow of a heating and / or cooling medium via a space heat exchanger (Raumwaermetauscher) of a heating or cooling plant, in which the adjustable and / or Alternatively, fixed limits can be used to regulate the target divergence (Zielspreizung) of the process temperature (Vorlauftemperatur) and return temperature (Ruecklauftemperatur) of the individual room heat exchangers. Background technique [0002] Usually such a method is used in order to limit the flow through the individual space heat exchangers which can be adjusted by the user by means of the space heat exchanger valves in the heating installation, so that then, when the valves are fully opened, all the space heat exchangers The heat exchangers are supplied with heating medium such that the same bifurcation (hydraulic balance) occurs at all space heat exchangers. The reason for the different supply of heating medium is that the hydraulic...

However, the particularly low temperatures in the spaces next to the high-temperature spaces lead to heat losses in the high-temperature spaces (especially when the doors are open), so that the space heat exchange must again be operated at a very high heating power in order to maintain the required temperature in these spaces heater, which generally increases the overall return temperature of the system and thus reduces the efficiency of the heating equipment
