Emulation of HVAC Control Systems Based on TRNSYS

The development and challenge of control strategies emulation are expounded. The air loop system and water distribution sys-tem in VAV system are modeled in TRNSYS,base case and improved case of control strategies are built. Then the issues on modeling process with solutions are discussed,analyzing the result of emulation and assessing the ability of emulation with TRNSYS to provide some ideas for further development of control strategies test bed. The result shows that TRNSYS is comparatively feasible and reliable tool even there are some disadvantages.
