NODE FOR CONNECTING BUILDING HEATING SYSTEM TO SYSTEM FOR FEEDING HEAT CARRIER

摘要

The invention relates to systems for heating buildings or structures. Technical result: increasing the number of options for connecting a system for heating a building or structure to a centralized system of mains for feeding a liquid heat carrier, and carrying out the connection, wherein the system for heating a building or structure does not require an expansion tank or a circulation pump in order to function. A node for connecting a system for heating a building or structure to a centralized system of mains for feeding a liquid heat carrier contains a heat exchanger (1) with a first loop (2) and a second loop (3) for exchanging heat, each of which has an inlet (4, 5) and an outlet (6, 7). a feeding pipeline (8) of the centralized system of mains for feeding liquid heat carrier is connected to the inlet (4) of the first loop (2) of the heat exchanger (1), and a feeding pipeline (9) of the system for heating buildings or structures is connected to the outlet (6) of said first loop, and is connected to heating devices (10). A return pipeline (11) of the system for heating buildings or structures is connected to the inlet (5) of the second loop (3) of the heat exchanger (1), and a return pipeline (12) of the centralized system of mains for feeding liquid heat carrier is connected to the outlet (7) of said second loop.
