Abstract

The invention provides an adaptive dynamic thermal load adjusting and controlling method. The adaptive dynamic thermal load adjusting and controlling method is used in a heating system to realize quality joint debugging according to change of the dynamic heat load. According to the method, the influence of cold air infiltration and solar radiation is further considered on the basis of the outdoortemperature, so that the indoor thermal load is adjusted and controlled more accurately, the stable indoor temperature is achieved, and the considerable heat-saving effect is achieved; and meanwhile,a heat network is made to run in a variable differential pressure and variable flow mode, and electricity saving is achieved while heat saving is achieved.

Description

technical field [0001] The invention belongs to the field of automatic heat supply regulation, relates to the on-demand heat supply regulation of a heat supply system, in particular to a method for self-adaptive dynamic heat load regulation of a heat supply system. Background technique [0002] my country needs a large area of ​​heating, and there are a large number of heating equipment in use, most of which do not have heat load control devices, and a small number of heating systems are equipped with climate compensators. Since the climate compensator is based on the temperature regulation of the steady-state heat load, and it is an open-loop feed-forward control, the regulation effect is not good, and manual intervention is often required for normal use. Moreover, there is almost no flow regulating equipment in the second network, and they all operate in the mode of large flow and small temperature difference, which wastes a lot of electric energy. [0003] The steady-sta...
