This study describes the research and development of a simulation-optimization of a building Heating, Ventilation, and Air-Conditioning (HVAC) system focusing on both temperature and humidity control. Adequate humidity control is critical for the energy efficient operation of buildings, human comfort and health, building materials, and product quality. With the increased demand for fresh air in buildings, it becomes apparent that much more research is needed in humidity control and thermal comfort issues. This study emphasizes this humidity control issue through investigating various promising HVAC equipment operating techniques. The main goal of the study is to provide a systematic framework and guideline for the optimal operation of HVAC systems focusing on air-side. There has been no such comprehensive information available in the open literature. A computer simulation model of a direct expansion (DX) air-conditioning system was developed to simulate various operational strategies. A commercial building type, retail store under humid climate was analyzed. For a given cooling loads and ambient outdoor conditions, the optimal operating strategies are determined by minimizing a constrained objective function by a nonlinear programming technique. Desired space setpoint conditions were found through evaluating the trade-offs between comfort and power consumption. The results show that supply airflow rate and compressor fraction play main roles in the optimization process. It was found that variable setpoint optimization technique could produce lower indoor humidity level demanding less power consumption which will be benefits for building applications of humidity problem.
