针对一种用于太阳能空调系统的分区蓄热水箱,对其运行情况进行了分析,结果表明,采用分区蓄热水箱来匹配太阳能空调能显著提高系统的性能。在夏季,分区水箱使得运行热水长时间内维持在较高温度,系统制冷COP也得以长时间维持在较高范围,虽然,在夜间无日照的情况下,系统的日工作时间减小了,但系统整体性能得以提高,尤其经过优化后,系统性能提升显著;同时,夏季的水箱结构较好地适用于冬季,在达到供暖要求的情况下,使得冬季系统的散热量降低,系统更为节能。总体而言,分区水箱应用于太阳能空调系统可以减小辅助能源的消耗,提高太阳能利用率。
Aiming at a district heat storage water tank used in solar air conditioning system, the operation of the district heat storage water tank is analyzed. The results show that the use of district heat storage water tank to match the solar air conditioner can significantly improve the performance of the system. In summer, the district water tank keeps hot water running at a relatively high temperature for a long time, and the COP of the system is maintained for a long period of time. Although the daily work time of the system is reduced under no sunshine at night, But the system overall performance can be improved, especially after optimization, the system performance improvement significantly; the same time, the summer tank structure is better suited to the winter, meet the heating requirements of the case, making the winter heat dissipation system reduces the system more energy . In general, the use of zoned water tanks in solar air-conditioning systems can reduce the consumption of auxiliary energy and increase the utilization of solar energy.
