摘　　要：实现“双碳”目标,需要提升新能源利用率并解决储能相关问题。相变材料(PCM)因其独特的物理特性能够在特定的温度下存储和释放能量,在能量存储方面有很广泛的应用。中低温相变储能技术的应用主要集中在建筑节能方面。分析了相变储能技术与热泵技术结合,在提升热泵的性能系数(COP)、减少热泵除霜时间和存储热泵热量/冷量等方面的应用进展情况。两者结合,能有效提升热泵COP、热泵机组运行稳定性以及用户端的舒适度,在建筑节能领域有着广阔的应用前景。指出了实际应用中存在的温度匹配、功率匹配、系统成本等问题,为未来研究提供可参考方向。Phase change material(PCM)can store and release energy at a specific temperature because of its unique physical properties. It has a widespread use in energy storage. Medium and low temperature phase-change energy storage technology is mainly applied to building energy conservation. To facilitate the integrated application of phase-change energy storage technology and heat pump technology,the ways to improve the coefficient of performance(COP)of heat pumps,reduce the defrosting time of heat pumps and strength the heat/cold storage capacity of heat pumps are analyzed.The integrated application can effectively improve heat pump COP,operational stability of heat pumps and the comfort level of users. This integration is promising in the field of building energy conservation.
