摘要
提出一种太阳能吸收子系统过冷压缩循环的新型压缩吸收耦合热泵系统,由压缩子系统、吸收子系统和太阳能集热子系统3部分组成;在夏冬两季均可使用。针对该新型太阳能热泵在恒定工况下的制冷、制热性能进行稳态实验研究。实验结果显示,夏季制冷时,在冷冻水进口温度12℃,冷凝器出口制冷剂温度50℃时,新型太阳能热泵系统的制冷最低COP为4.02,与同工况的常规压缩热泵相比,制冷COP提高13.88%;冬季制热时,存在COP的极值转变温度。在实验环境温度为16℃,冷凝器热水出口温度59℃时,新型耦合系统最小的制热COP为5.44,与同工况常规压缩热泵相比,制热COP提高11.52%。显示了新型系统的巨大优势,具有良好的应用前景。
This article provides a new compression heat pump system coupled with solar absorption by absorption subsystem subcooling compression cycle.It is composed of three parts:a vapor-compression subsystem,an absorption subsystem and a solar heat collected subsystem,and this system can be used in summer and winter.The article shows a steady-state experimental research of cooling/heating performance of this new system at constant conditions.When cooling in summer,the new system’s minimum cooling COP is 4.02 with cooled water in the evaporator inlet at the temperature of 12℃ and refrigerant in condenser outlet at the temperature of 50℃.As compared with conventional compression heat pump at the same constant condition,the novel system cooling COP improves by 13.88%.When heating in winter,there is a turning temperature of COP.The new coupled system’s minimum heating COP is 5.44 with the environmental temperature of 16℃ and hot water in condenser outlet at the temperature of 59℃.As compared with conventional compression heat pump at the same constant condition,the new system heating COP improves by 11.52%.It shows that the new coupled system has huge advantages and will have an excellent future.
