摘要

为提升建筑空调系统用能柔性并适配冬夏差异化供能需求，本工作提出一种开式非承压、可更换相变材料的新型管壳式储能水箱，并将其集成于常规空气源热泵系统中。通过实验与数值模拟相结合的方法，系统研究了该复合系统在冬、夏双工况下的蓄放热性能与用能调节能力。结果表明：冬季运行时，通过调节风机盘管设定温度(20~24℃)与风速(850~1430 m

/h)，相变储能水箱的释热时长可在48~90 min内调节，提升幅度达87.5%，系统用电削减率为89.2%~95.3%；夏季实验验证了系统释冷工况的可行性与稳定性，模拟结果表明完全蓄冷后可支持连续供冷约155 min。此外，模拟优化显示连续蓄热时间较实验可缩短约57

%。本工作通过结构创新与运行模式设计，显著提升了空气源热泵系统在制冷制热双工况下的用能调节能力，为相变储能在建筑空调中的应用提供了技术参考。

Abstract

To enhance the energy flexibility of building air conditioning systems and meet distinct seasonal energy supply demands

this study proposes a novel open-type non-pressurized shell-and-tube phase-change energy storage tank

which allows convenient replacement of phase change material

and integrates it into a conventional air-source heat pump system. The thermal performance and energy regulation capacity of the integrated system under two operating modes were systematically investigated through combined experimental and numerical approaches. Results show that during winter operation

by adjusting the fan-coil unit set temperature (20—24℃) and fan speed (850—1430 m

/h)

the heat release duration of the phase-change energy storage tank could be regulated from 48 min to 90 min

representing an increase of up to 87.5%

while the system's electricity consumption reduction reached 89.2%—95.3%. Summer experiments verified the feasibility and operational stability of the cooling release mode. Simulations indicated that a fully charged tank could sustain continuous cooling for approximately 155 min. Furthermore

simulation-based optimization suggested that the full heat storage time could be shortened by about 57% compared to the experimental conditions. Through structural innovation and operational mode design

this work significantly improves the energy regulation capability of air-source heat pump systems under both heating and cooling conditions

offering a technical reference for the application of phase-change energy storage in building air conditioning.
