Heat Transfer and Optimization

Thermal energy storage (TES) is recognized as an important technique for energy management in heating, ventilation and air conditioning (HVAC) systems. This paper discusses the economic aspects of the optimal design for such systems. The model for optimal design so determines the sizes of the main components of the system - namely the chiller and the storage tank - that the system's life cycle cost is minimal. The model is based on linear programming and is implemented in a computer program for HVAC systems with ice storage. This paper demonstrates that the optimal sizes of chiller and storage tanks differ from those selected using traditional techniques. It emphasizes the cost-effectiveness of the optimally designed system and also includes a sensitivity analysis pertaining to the economic feasibility of such systems under different economic conditions.
