新型相变储能装置在热泵系统中双工况运行特性与用能调控研究
Research on energy regulation of air source heat pump air-conditioning system based on new phase change energy storage device
摘要
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 m3/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.关键词
