ONE-PIPE HYDRONIC HEATING CONTROL DEVICE

摘要

The device for heat exchanger output control in a one-pipe heating network provided with the secondary supply pipe connection (15) on the inlet pipe (16) of the exchanger (2) and the secondary return pipe connection (18) on the return pipe (17) of the exchanger (2) that is connected to the primary inlet pipe (7) from the heat source through the primary inlet pipe connection (8). The first T-branch (4), which is connected to the second T-branch (5) interconnected to the primary outlet pipe connection (11) of the primary outlet pipe (12) to the heat source through the primary outlet (10), is connected to the primary inlet pipe connection (8) through the primary inlet (9). The first T-branch (4) is connected to the secondary supply pipe connection (15) through the secondary supply pipe (13) with the secondary supply temperature sensor (20), and the second T-branch (5) is connected to the secondary return pipe connection (18) through the secondary return pipe (19) with additional secondary return temperature sensor (22). An impeller of the pump (3) is connected to the secondary circuit to pump the heat-transfer medium from the first T-branch (4) through the heat exchanger (2) back to the second T-branch (5), wherein the pump impeller (3) is connected to the electrical motor (25) provided with the control unit (6) connected to the secondary supply temperature sensor (20) and additional secondary return temperature sensor (22).
