摘　　要：建筑能耗在能源消费中充当着一个重要的角色,其中供暖供冷的能耗在建筑能耗中又占有较大的比例。能源与环境问题要求各种低位可再生能源逐渐取代暖通空调系统对高位热能的消耗。这可以通过热泵技术来实现。再生水包含着生活和生产过程中排出的各种废热,可以作为水源热泵的冷热源。同时结合蓄能技术,既可避免再生水量变化影响系统的稳定性,又能进一步降低运行费用,这在供冷供暖主要集中在白天的办公建筑尤为突出。结合项目案例介绍了再生水热泵和蓄能水池的系统设计,主要包括再生水热泵设计、蓄能系统设计等,并根据冬夏两季的负荷特点分析了系统相应的运行策略,在相应的运行策略下与常规的供暖供冷系统的运行情况作了比较,肯定了再生水作为冷热源在供暖供冷中的应用,为再生水在热泵系统中的应用提供了一定的参考。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.
