Problems solved by technology

The temperature difference model uses a single outdoor temperature change as the basis for calculating the load. It is not necessarily accurate. The heat load is determined by multiple factors such as the outdoor temperature, solar radiation intensity, wind speed, heat storage performance and heat conduction performance of the enclosure result, and is a dynamic change. process, so the traditional temperature difference control mode has certain deficiencies in control accuracy
In the actual operation of the metered heating system in the differential pressure control mode, there are random self-adjustments by the end users, which will affect the heating effect of the entire system

Abstract

The invention discloses an energy-saving control method of a centralized heating system. An actual combustion heat sequence of each terminal equipment in the centralized heating system is firstly obtained; then, predicted consumption heat of each terminal equipment in the next unit time period is calculated according to the actual consumption heat sequence; and finally, a water supply flow and a water supply/return temperature of a heat exchange station to the centralized heating system are controlled according to the predicted consumption heat. The energy-saving control method of the centralized heating system not only can effectively reduce the operation energy consumption of the centralized heating system, but also can guarantee the heat use comfort of terminal users.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to an energy-saving control method of a central heating system. Background technique [0002] The energy-saving optimization control strategy adopted by the current central heating system is based on the concentration effect of all current end-user heat loads, which is a control of the average effect of the entire system. For example, the most widely used circulating water pump frequency conversion control technology is based on the current system load change as the basis to adjust the circulating water flow to reduce the energy consumption of the circulating water pump. The control modes mainly include "temperature difference" and "pressure difference". "Two modes. The temperature difference model uses a single outdoor temperature change as the basis for calculating the load. It is not necessarily accurate. The heat load is determined by multiple factors such as outdoor temperatur...
