摘要: “双碳”目标下,热电、化工、能源等高能耗类企业都将面临着巨大的挑战。储热材料直接影响着换热体系
的效率和成本。因此,选择合适的相变温度、合适的储热密度,并合理考虑经济性,是相变储热技术进一步发展需要综
合考虑的问题。结合实际,着重介绍了高温相变储热设备与空气源热泵的结合应用,利用峰平谷电价,计算在不同室外
温度和不同空气源热泵平均性能系数下的设备运行成本,提出一种经济节能的供热运行方式。高温相变储热设备具有占
地小、储热高、放热均匀等特点,在热能储存、余热回收和供热领域具有广阔的市场空间和应用前景。相变储热过程中
释放潜热温度不变,因此供热平滑稳定,在市场应用中有着独特的定位。相比于常规的显热储能材料,高温相变储热材
料释放的潜热更加稳定平滑,更能对极端的工艺放热进行有益补充。

Abstract: Under carbon peaking and carbon neutrality goals, thermal power, chemical industry, energy and other high-energy
consumption enterprises will face huge challenges. The quality of the heat storage material directly affects the efficiency and cost
of the heat exchange system. Therefore, choosing the appropriate phase change temperature and the appropriate heat storage
density and reasonably considering the economy are the further development problems of the phase change heat storage
technology. Realistically, this paper focused on the combination of high temperature phase change heat storage equipment and air
source heat pumps. By using peak and valley electricity prices to calculate the equipment operating costs under different outdoor
temperatures and different average performance coefficients of air source heat pumps, an economical and energy-saving heating
operation mode was proposed. High temperature phase change heat storage equipment has the characteristics of small footprint,
high heat storage, and uniform heat release. It has broad market space and application prospects in the fields of heat storage,
waste heat recovery, and heating. The temperature of latent heat released during phase change heat storage remains constant,
resulting in smooth and stable heating, and has a unique positioning in market applications. Compared to conventional sensible
heat storage materials, high temperature phase change heat storage materials release more stable and smooth latent heat, which is
more beneficial to supplement extreme process heat release.
