Summary

This paper presents the experimental investigation of a water-based thermal energy storage (TES) unit using PCMs in a heating, ventilation and air conditioning system (HVAC) of a Solar Decathlon (SD) house. The integration of the PCM TES unit in the air conditioning system aims to facilitate energy management and reduce the operational cost for indoor air conditioning, through temporary cool energy storage over off-peak periods and controlled release during on-peak periods for space cooling. A series of experiments were undertaken to study the charging performance of the PCM TES unit using an air-to-water heat pump. The experimental investigation revealed the dynamic charging characteristics of the PCM TES unit coupled with the heat pump. Further analysis based on the experimental data resulted in an optimal charging strategy for the charging process of the PCM TES unit using the air conditioning system.
