Heat supply network balancing system

Abstract

The invention discloses a heat supply network balancing system. The heat supply network balancing system comprises a water inlet pipe and a water return pipe; the water inlet pipe is provided with a filter, a water pump and a water inlet temperature sensor at a user side in sequence according to the water flow direction; the water return pipe is provided with a water return temperature sensor at the user side, a manual balance valve and a pressure difference control valve with a flow rate adjusting function in sequence according to the water flow direction; a check valve is arranged between the water inlet pipe and water return pipe; the water pump is provided with a transducer; the pressure difference control valve, water inlet temperature sensor at the user side, water return temperature sensor at the user side and outdoor temperature sensor are connected with a controller with a weather compensation function through circuits; each of the water inlet pipe and water return pipe is provided with a thermometer and a pressure gauge, and shut-off valves are arranged at two ends of each of the water inlet pipe and water return pipe. The heat supply network balancing system realizes the variable-flow rate intelligent heat usage of a secondary network of the heat supply network, the return water at the user side is mixed with the primary side inlet water of the system, the return water energy of the user side is completely used, the comfort is improved for the user, and the energy conservation and environment protection are realized.

Description

technical field [0001] The invention belongs to the technical field of heat energy saving, and in particular relates to a heat network balance system. Background technique [0002] The common problem in the current heating network is that the water supply end of the heating station pays a lot of heat, but the building is unevenly cooled and heated, the room temperature is uncomfortable, the users are not satisfied, and it is difficult to charge. In order to solve the problem, the heat exchange station is forced to operate with a small temperature difference and a large flow rate, resulting in low heat conversion efficiency and high power consumption of the circulating water pump. Therefore, the automatic control equipment such as the automatic temperature control system and the frequency converter in the heat exchange station cannot exert their energy-saving function and potential due to the "barrel effect" of the secondary network of the heating network, the heat supply of ...

[0002] The common problem in the current heating network is that the water supply end of the heating station pays a lot of heat, but the building is unevenly cooled and heated, the room temperature is uncomfortable, the users are not satisfied, and it is difficult to charge

In order to solve the problem, the heat exchange station is forced to operate with a small temperature difference and a large flow rate, resulting in low heat conversion efficiency and high power consumption of the circulating water pump

Therefore, the automatic control equipment such as the automatic temperature control system and the frequency converter in the heat exchange station cannot exert their energy-saving function and potential due to the "barrel effect" of the secondary network of the heating network, the heat supply of automatic climate compensation cannot be realized, and the circulating water pump cannot Cannot run automatically with variable frequency according to actual needs

The traditional solution is to use balanced valve adjustment, but the heat supply cannot be controlled, the heat cannot be used intelligently, the cycle power saving is limited, and the internal transformation cost of the user is high, which is difficult to realize
