摘要(Abstract):
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。
A type of partitioned heat storage tank used in solar air conditioning was discussed,and the performance characteristics were analyzed,the results show that the partitioned tank using in solar air conditioning system can improve the property of the system.In summer,the operating temperature of the hot water tank with a subarea can maintain in a long time,and the COP of the system also can keep in a high range,in the night,no sunshine,the working time of the system will decrease,but the property of the entirety system was improved,especially,through the optimized design,the improve was displayed obviously;meanwhile,the tank used in summer was suitable for the condition in winter,with meeting the demand of the heating,the heat release was reduced and the energy was saved.In general,since the partitioned tank using in solar air conditioning system,the consumption of the auxiliary energy can decrease and the solar energy utilization ratio can improve.
