A New Type of Energy Efficient Central Heating System

摘要

In order to improve the reliability of central heating, reduce heating costs, realize economic and energy-saving operation, the paper presents a new type of heating system, and gets some important conclusions by comparing the new system with the traditional heating system(two-pipe closed multi-heat sources). In the new central heating system, heat medium flows through every heat source orderly, which facilitates heating load allocation among multi-heat source and realization of economic operation. Stable hydraulic condition can facilitate network operation, and multi-heat-source adjustment and operation regulation, and control of heat metering system. In addition, the tnmk line, as a single-pipe system, when laid with double-track, can eliminate throttling energy, achieve energy-saving operation and improve reliability of heat supply. Moreover, hydrodynamic pressure totally decreases, which expands application scope of directconnected users (mixing water directly connected with users) and reduces the initial investment of central heating system.
