SIMULATION ON INDOOR THERMAL DYNAMIC PERFORMANCE OF HEATING SYSTEM UNDER THE ON-OFF VALVE ADJUSTING MODEL
In order to solve the unbalance problem and increase the system efficiency of central heating, a new-style adjusting model in the building internal system —on-off valve adjusting system which is composed of by the on-off valve 、controller 、 indoor temperature sensor is put forward. According to the heat transfer process, dynamic models of water-flow, radiator, and building are established to solve the indoor temperature variation of individual rooms under different loads and different on-off control strategies, based on which the impacts of different temperature and rate of the water-flow on control strategy are studied, then an on-off control strategy with intelligent feedforward is obtained.
