Dynamic and real-time simulation of EMS and air-conditioning system as a 'living' environment for learning/training

Dynamic and real-time simulation models are developed to simulate the thermal, hydraulic, mechanical, environmental and energy performance of building a variable air volume (VAV) air-conditioning system and its building management system (BMS). On-line direct digital control (DDC) and supervisory strategies of the EMS controlling the dynamic air-conditioning system are simulated. A window-based users interface is developed to simulate the man-machine interface of a BMS, through which users can monitor the on-line operation, tune the local control loops, and reset the supervisory control strategies. This paper presents models, simulation software, and examples that users practice on the simulated on-line BMS and air-conditioning system using the software. (C) 2001 Elsevier Science B.V.
