Abstract

In this study, a low-carbon solar water heating system integrated with salt hydrates as storage mediums was developed. The thermal performance of the heating system was tested using a full-scale experimental platform. A performance comparison was conducted between the system using sodium acetate trihydrate (SAT)-acetamide (AC) and one using SAT. The heating system incorporating the SAT-AC (phase-change temperature: 47.8 °C) showed an approximate 5.3% increase in the coefficient of performance compared to the system using SAT (phase-change temperature: 56 °C). Additionally, the discharging time for the SAT-AC unit was extended, benefiting from its optimal phase-change temperature. These findings indicate the promising potential of the selected salt hydrates for solar water heating applications and provide valuable guidelines for designing efficient heating systems.
