摘要
提出一种将闭式能源塔热泵技术与自复叠系统相结合的热泵系统,该系统在保证提供55℃热水的前提下,利用自复叠系统-39℃^-14℃的蒸发温度,通过能源塔提取空气能,实现冬季寒冷地区的能量传递,系统运行中通过制冰浓缩方式控制乙二醇喷淋液的浓度;通过REFPROP软件,进行了该热泵系统的热力分析;分析表明,系统具有较好的可行性。
A heat pump system of the combination of a closed type of energy tower heat pump technology and the auto cascade system was presented in this paper. Based on auto - cascade system with an evaporation temperatures of 39℃ to 14℃, the system could provide heat water at 55℃, extract low heat source in the air throughout the energy tower and transport energy be- tween regions. Meanwhile, it controls ice concentration of ehylene glycol. Then, based on the REFPROP software, the analysis of the thermodynamic properties of the system was completed and the feasibility of the design was determined.
