This paper systematically presents a thorough analysis on the construction of the heating monitoring system in Nanjing General Hospital, China. The monitoring method and strategy of were discussed in detail. Besides, the optimization design of the simple closed loop control system was conducted. Finally, an optimal operation analysis system consisting of the heating host machine, costumer thermal monitoring system, and outside environment monitoring system for the heating room was established. As a result, the heating quality, the heating efficiency, and the relationship with costumer were greatly improved.

Operating Modes

Three operating modes of district heating system are introduced and the operating parameters are compared. To find out the most energy-saving one, an experiment is carried out in a cogeneration plant. An operating mode using variable frequency circulating pump for flow control at a constant supply and return water temperature difference is proposed. The conclusion shows that using variable frequency circulating pump is a more energy-saving method.
