Example Embodiment

[0049] In order to further explain the features of the present invention, please refer to the following detailed description of the present invention and the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the protection scope of the present invention.

[0050] Such as figure 1 As shown, this embodiment discloses a method for adjusting the primary water flow rate of a heat exchange station, which includes the following steps S1-S2:

[0051] S1. Obtain the outdoor average temperature, and find the secondary side target control temperature corresponding to the outdoor average temperature in the data comparison table of the outdoor average temperature and the secondary side target control temperature;

[0052] S2. The target control temperature of the secondary side is compared with the average temperature of the actual supply and return water on the secondary side, and the primary side water flow is adjusted accord...

Abstract

The invention discloses an adjusting method and system for primary side water flow of a heat exchange station, and belongs to the technical field of city and town centralized heating. The adjusting method includes the steps that the outdoor average temperature is obtained, and a secondary side target control temperature corresponding to the outdoor average temperature is searched for in a data comparison table of the outdoor average temperature and the secondary side target control temperature; and the secondary side target control temperature is compared with a secondary side actual supply and return water average temperature, and the primary side water flow is adjusted according to the comparative result. Due to the fact that the corresponding secondary side target control temperature atthe outdoor average temperature is used as a basis for adjusting the primary side water flow, the adjustment amplitude of the opening degree of a primary side electrically operated valve or the adjustment amplitude of the operating frequency of a primary side circulating pump is made small, and the phenomenon of frequent fluctuations of first-level network flow and transmission and distribution heat is avoided.

Description

technical field [0001] The invention relates to the technical field of central heating in cities and towns, in particular to a method and system for adjusting the primary side water flow of a heat exchange station. Background technique [0002] At present, unattended heat exchange stations for centralized heating generally use PLC to control the average temperature of the supply and return water on the secondary side by automatically adjusting the opening of the electric valve on the primary side / frequency of the circulating pump according to the real-time outdoor temperature, so as to meet the heating needs of users. , to achieve the purpose of energy saving. [0003] However, this adjustment method makes the opening of the electric valve on the primary side / the frequency of the circulating pump and the flow rate on the primary side produce frequent periodic and large-scale oscillations due to the outdoor temperature that changes periodically during the day and night. If m...
