A heat network balance system

Abstract

The invention provides a heat network balance system, which includes a water inlet pipe and a water return pipe; a filter, a water pump, and a user-side water inlet temperature sensor are sequentially arranged on the water inlet pipe according to the direction of water flow; Water temperature sensor, manual balance valve and pressure difference control valve with flow adjustment function; check valve is installed between the water inlet pipe and return water pipe; frequency converter is installed on the water pump; pressure difference control valve, water inlet temperature sensor on the user side, Both the return water temperature sensor on the user side and the outdoor temperature sensor are connected to the controller with climate compensation function through a circuit; there are thermometers and pressure gauges on the inlet and return pipes, and the two ends of the inlet and return pipes Each is provided with a shut-off valve. The invention realizes the intelligent use of heat by changing the flow rate of the secondary network of the heating network, utilizes the return water on the user side to mix with the primary side water in the system, fully utilizes the energy of the return water on the user side, improves user comfort, and is energy-saving and environmentally friendly.

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
