Simulated Evaluation of Combined Use of Building Thermal Mass and Thermal Storage in Solar Hybrid Heat Pump System for Demand Response
Abstract
In this study, TRNSYS simulations were employed to evaluate simple strategies for controlling energy demand response by utilizing building thermal mass and daily and weekly solar thermal storage. All control setpoints (i.e., for the building indoor space temperature, for heat pump on/off controls, and for pump and valve control for the weekly storage tank) were adjusted before and during the demand response period. Simulation results showed that a significant reduction in electric energy consumption could be achieved through combined use of thermal storage.
