Novel heating hydraulic balance heat supply method

Abstract

The invention discloses a novel hydraulic balance heat supply method. An electric flow control valve is installed on a backwater portion of a primary network of each heat exchange station, and the purpose of hydraulic balance of the primary networks is achieved. The method comprises the steps that self-operated type flow control valves are installed for users in the heat supply regions below the heat exchange stations; the self-operated type flow control valves are adjusted according to resident indoor temperature target values, and the initial flow of each user is set; movable type temperature sensors are installed for heat supply typical users, and the indoor temperature is automatically monitored; the initial flow of the self-operated type flow control valve of each typical user is adjusted according to the difference between the temperature of the typical user and the target temperature, and therefore the resident indoor temperature can be same or similar; and circulating water pumps and heating equipment are improved, a heat supply running medium adjustment curve is set, and the supply water temperature is controlled according to the heat supply running medium adjustment curve. By the adoption of the novel hydraulic balance heat supply method, the hydraulic balance of the primary networks of the heat exchange stations can be achieved, the purpose that the resident indoor temperature of all heat supply users in the heat supply regions is same or similar is achieved, the user complaint rate is reduced, and the energy is substantially saved.

Description

technical field [0001] The invention relates to the technical field of heat supply balance, in particular to a new method of hydraulically balanced heat supply for heating, which makes the primary heating network balanced and the room temperature of the secondary network households the same or similar. Background technique [0002] The performance of hydraulic imbalance in the heating system is: the imbalance between the heat exchange stations in the primary network, and the heat energy demanded by a certain heat exchange station is different from the heat energy supplied. In the heat exchange station of the secondary network (favorable loop), the temperature of the near-end residents is too high, and the temperature of the far-end (unfavorable loop) is too low. With the measures taken, the whole system is in the operating state of large flow and small temperature difference, which is not conducive to the temperature of the residents in the loop to reach the standard, and it...
