Heat supply two-network balancing method

Abstract

The invention relates to a heat supply two-network balancing method. The heat supply two-network balancing method comprises the following steps that a heat supply model of heat supply two-network balance is established, and the heat supply two-network balance involves in-building heat supply balance and heat supply balance among building units; buildings are divided into high areas, middle areas and low areas according to the height, and a variable frequency pump is arranged on a starting floor of each height area; a heat supply balance neural network of each height area is constructed, the frequency of the variable frequency pumps is obtained, and according to the adjustable range of the variable frequency pumps, a circulation control instruction is activated to achieve heat supply balance in the building; and parameters of all building units in the heat supply range of each heat exchange station are obtained regularly, a heat supply two-network balance neural network is constructed, the water supply flow is adjusted, and heat supply two-network balance is achieved. According to the heat supply two-network balancing method, on the basis of ensuring heat supply balance among the buildings, the heat supply balance in the buildings is met to the maximum extent, heat energy is saved according to the principle of large temperature difference and small flow, and electricity consumption of a water pump is reduced.

Description

technical field [0001] The invention relates to the technical field of heating systems, in particular to a method for balancing two heating networks. Background technique [0002] At present, the phenomenon of hydraulic imbalance in the secondary pipe network is common in heating enterprises. The pipe network consumes a lot of electricity, has low thermal efficiency, and high operating costs. Moreover, hydraulic imbalance can easily lead to uneven temperature and heat, and a large number of complaints. [0003] The traditional heat supply adjustment method generally requires repeated temperature measurement and adjustment, which is a heavy workload, time-consuming and labor-intensive, and the effect is not good. Since the heat exchange station and the second network equipment are adjusted separately, there is no overall linkage, and the control idea is too simple; at the same time, the second network balance adjustment adopts the flow adjustment method, which is usually adju...
