Summary: In this study, the performance of a Solar Water Tank (SWT) integrated with Nano-enhanced Phase Change Material (Ne-PCM) and a Stirrer was experimentally assessed. Two configurations of SWT/Ne-PCMs, a spiral-type and a jacketed shell-type heat exchangers, were designed and developed. The experimental results showed that the completion time for the SWT/Ne-PCM charging and discharging processes was reduced by 12.5% and 23.51% respectively, when a stirrer and a coil were used.

Summary: Research on phase change materials (PCM) in building energy efficiency has rapidly developed in the past decade. The static PCM-based building envelopes lack flexibility in adjusting heat storage and release, resulting in low efficiency. The application of adaptive dynamic building envelope integrated with PCM (ADBEIPCM) addresses this issue. This paper systematically reviewed ADBEIPCMs for the first time, including their configuration, principles, control strategies, and performance. Research methods and PCM properties were also summarized.

Summary: The use of thermal storage, particularly latent heat storage, can effectively address the fluctuating availability of solar energy. The integrated collector storage and separate collector storage designs are the most practical in combination with solar water heating systems. This article extensively reviews these designs and examines the impact of operating parameters. The study finds that evacuated tube collectors have significantly better thermal efficiency than flat plate collectors in the integrated collector storage design, while different designs of latent heat storage units have similar thermal performance in the separate collector storage design.

Summary: This study presents a novel dynamic model for a latent cold thermal storage unit using water as the phase change material (PCM). The model integrates transient energy balances for PCM capsules and heat transfer fluid (HTF), and uses the apparent heat capacity approach to simulate PCM phase transition processes. The model is validated through experimental data and used to analyze the influence of various parameters on storage performance. The results show that the melting process of PCM varies in different directions within the storage unit. The study also suggests that the height of the tank and the diameter of the capsules impact the discharge period, while the initial temperature of the storage tank has minimal effect. To improve performance and reduce energy consumption, a compromise between HTF flow rate and capsule diameter needs to be determined.
