Energy storage technology is crucial for promoting the replacement of traditional energy with renewable and regulating supply–demand relationship. This paper investigates a triplex-tube thermal unit to solve intermediate heat transfer problem hot water supply demand in clean heating systems. A multi-objective optimization method based on elitist non-dominated sorting genetic algorithm (NSGA-II) was utilized optimize geometric dimensions (inner tube radius r1, casing r2, outer r3), focusing efficiency (ε), rate (Pt), mass (M). On this basis, influence variables analyzed. The optimized configuration (r1=0.014 m, r2=0.041 r3=0.052 m) integrated into modular design, achieving 2.12% improvement 73.23% increase rate. Experimental results revealed that higher fluid (HTF) temperatures significantly reduce time, while HTF flow has minimal impact. Increasing release temperature extends phase change material (PCM) duration, showing negligible effects. system’s capacity susceptible temperature.
