Abstract :
Dynamic models are developed to simulate the thermal, hydraulic, environmental and mechanic characteristics and energy performance of a building and VAV air-conditioning system under the control of EMCS. Three on-line supervisory strategies and programs based on integrated EMCS stations are developed to optimise the VAV static pressure set-point, AHU outlet air temperature set-point and outdoor ventilation air flow set-point, The strategies and programs are commissioned and evaluated under the simulated ‘real-life’ environment. This paper presents the dynamic models, the control strategies and the simulation exercises for commissioning and evaluation of the strategies.
