Analysis of energy saving performance for central heating systems under intelligent on-off regulation mode

Puts forward the limitation of unified constant flow control for central heating system. Based on indoor heating systems with different connection modes, analyses the energy saving effect of intelligent on-off regulation by means of simulation method. The result shows that compared with ideal constant flow control, on-off regulation saves energy obviously and can reduce energy consumption by 33% in horizontal one-pipe series system, 30% in vertical one-pipe series system and 20% in college dormitories when low temperature control scheme is adopted in winter vacation.
