摘要
在环境污染和能源危机的双重背景下,太阳能是建筑供暖的首选能源。以太阳能光热+市电耦合相变蓄能(源侧及负荷侧)供暖系统为例,研究入口参数对相变蓄热装置蓄热过程的影响及有无相变蓄热地板对室温的影响。结果表明:提高入口温度和入口流量有利于缩短相变蓄热所需的时间;有相变蓄热地板的房间温度波动更平稳,舒适度更高。
In the dual context of environmental pollution and energy crisis,solar energy is the preferred energy source for building heating.A case study of a solar thermal+mains coupled phase-change energy storage(source side and load side)heating system is used to study the influence of inlet parameters on the heat storage process of the phase-change heat storage device and the influence of with or without phase-change heat storage floor on room temperature.The results show that increasing the inlet temperature and inlet flow rate is beneficial to shorten the time required for phase-change heat storage.Rooms with phase-change heat storage floors have smoother temperature fluctuations and higher comfort.
