The plate heat exchanger is the main source of heat for the building system based on microsubstations in the building apartments. The co-operation of the heat exchange station with the substations in the apartments is also described. Such microstations are intended for both domestic hot water preparation and apartment heating. The method of calculating the product of the heat transfer coefficient k and the heat exchange surface area A is presented. In order to verify the correctness of the measured values of the temperatures of hot and cold water at the heat exchange station inlet and outlet, they were compared to the values calculated using the -NTU method. Good agreement was found between the results of the calculations and the meas-urements. Recommendations were made for the temperature of return water to the heating station. The cost of operating the district heating network could be reduced by increasing the surface area of central heating radiators in apartments, so that the temperature of return water to the heating station could be lowered.}, type={Article}, title={Heat flow analysis and description of the cooperation of the heat exchange station with heat exchange substations located in apartments}, URL={http://journals.pan.pl/Content/132016/8_AOT-00749_2024_Taler.pdf}, doi={10.24425/ather.2024.151218}, keywords={Monitoring of the heat station, Plate heat exchanger, Heat exchanger efficiency, Building central heating, Res-idential micro heating station}, }
