This study presents a new integration of air-source heat pumps, solar collectors, and phase change material tanks regarding the dynamics of outdoor swimming pools, and investigates its application in outdoor swimming pools to extend their availability in the winter in subtropical climates. Since multiple heat sources are used, two issues in the development are addressed: (1) main component sizing and (2) multi-criterion design. The sizing problem is solved by considering the complementarity of different heating sources, while the multi-criterion design considers the initial investment, thermal comfort, operating costs, and energy use. Using TRNSYS and MATLAB combinations of different solar collector areas, air-source heat-pump heating capacities, and PCM tank volumes were investigated and analysed, among which optimal design was identified using a multi-criterion method. The proposed main components sizing and the multi-criterion design method could guide the design of a swimming pool heating system with multiple heat sources.

这项研究针对室外游泳池的动力学提出了一种空气源热泵，太阳能收集器和相变材料储罐的新集成，并研究了其在室外游泳池中的应用，以扩展其在亚热带气候冬季的可用性。由于使用多个热源，因此解决了开发中的两个问题：（1）主要组件的尺寸确定和（2）多标准设计。通过考虑不同热源的互补性来解决尺寸问题，而多标准设计则考虑了初始投资，热舒适性，运营成本和能源消耗。使用不同太阳能集热器区域的TRNSYS和MATLAB组合，对空气源热泵加热能力和PCM储罐容积进行了研究和分析，其中，使用多准则方法确定了最佳设计。提出的主要构件尺寸和多准则设计方法可指导具有多个热源的游泳池加热系统的设计。
