Design Analysis of Regenerative Water Heat Pump with Cool and Heat Storage
Building energy consumption plays a significant role in overall energy consumption,with heating and cooling representing a substantial portion of this.Energy and environmental challenges necessitate the gradual substitution of high-potential thermal energy consumption by HVAC systems with various low-potential renewable energy sources.This shift is facilitated by heat pump technology.Reclaimed water,containing waste heat from daily life and industrial processes,serves as both a cold and heat source for water source heat pumps.When combined with energy storage technology,this integration not only mitigates the effects of fluctuations in reclaimed water volume on system stability but also significantly reduces operational expenses,especially beneficial for office buildings where most cooling and heating occurs during daytime.This article presents the system design of a reclaimed water heat pump and an energy storage tank,drawing from project examples,which encompasses the design of the reclaimed water heat pump and the energy storage system.It analyzes the system's operational strategies based on the load characteristics of winter and summer seasons,contrasting these with the performance of conventional heating and cooling systems.The article affirms the utility of reclaimed water as a source for both heating and cooling,offering insights for its application in heat pump systems.
