Abstract: Variable Air Volume (VAV) box is a key unit to save energy and satisfy indoor thermal comfort in the VAV air-conditioning system. Dynamic control performance of VAV box is critical in designing and commissioning the VAV systems. This paper focuses on the development of simulation platform that facilitates the evaluation of control characteristic of VAV box. Co-simulation platform of indoor thermal environment is built by using software and hardware. The software sector of the simulation platform is composed of MATLAB® and FORCECONTROL® industrial Distributed Control Software (DCS). MATLAB can be used as strategy level algorithm execution and FORCECONTROL can be used as supervisory control and management. Programmable Logic Controller (PLC) is used as hardware sector to control the humidifier and heater to simulate indoor thermal load environment and test VAV box response performance. The evaluation outcomes help the engineers accelerate the process of regulating the VAV box and commissioning VAV system in the field.
