Analysis of Time-Sharing and Zoning Heat Load Demand and Research on Heating Control of Large Heating Buildings

Abstract

It is of practical significance to analyze the time-sharing and zoning heat load demand and fine heating control of large heating buildings in order to reduce the building energy consumption. The existing research lacks the time-sharing and zoning form of refined heating for different functional zones of large heating buildings. For this reason, this paper carried out the time-sharing and zoning heat load demand analysis and research on heating control of large heating buildings. First, the mathematical model for the main heating links of the heating system of the large building based on the heat balance equation is constructed to realize the simulation of the dynamic change of the performance of the large building heating system. Then, the size, characteristics and influencing factors of heat load of various heating units in the building are analyzed, and three possible ways of mass regulation, mass-flow regulation and intermittent regulation that can change the flow by stages are introduced. The experimental results verify the effectiveness of the proposed heating control mode, which can effectively reduce the building heating energy consumption.
