Predictive Control of Residential Heat Pump Water Heaters [SWR-13-35]
- National Renewable Energy Lab. (NREL), Golden, CO (United States)
Heat pump water heaters (HPWH) in the United States typically feature both a heat pump and at least one electric resistance element for heating. The heat pump is much more efficient than the element but cannot heat the water as quickly. The combination of these two heat sources makes HPWH a perfect candidate for implementing advanced control algorithms to achieve additional energy savings. NREL's Predictive Control of Residential Heat Pump Water Heaters introduces a novel predictive control method that provides optimal setpoint profile for both heat sources based on the patterns discovered from users' hot water use data. A simulation study indicates the Predictive Control of Residential Heat Pump Water Heaters is able to achieve significant energy savings without impacting users' thermal comfort.
