Heat supply system, especially for buildings, distributes thermal medium according to external parameter dependent on weather conditions when second load demands heat

摘要

The system has a heat source (2) for producing a thermal medium, first and second thermal loads (10,11) connected to the source via feed and return lines (8,9;12,13), at least one branch point (14) and a control element (15) for influencing the distribution of thermal medium flow between the loads. Distribution is performed according to an external parameter dependent on weather conditions when there is a demand from the second load.
