Real time simulation of on-line BMS and air-conditioning system for training/learning applications

摘要

A PC-based software, BMSonline, is developed to simulate a 'on-line' learning environment of BMS by simulating the BMS on-line DDC controls and supervisory strategies, the thermal, hydraulic and environmental characteristics and energy performance of a building and VAV air-conditioning system. A window-based user interface is developed for the users to monitor the online operation, to tune the DDC control loops and to modify the supervisory control strategies on-line and off-line. This paper presents the real-time simulation of the air-conditioning system and the BMS on-line controls, the user interface and examples for the users to practise and test the dynamic performance of BMS controls and air-conditioning system on the software.
