Table 4 Results compared to published work.
From: Performance assessment of thermal energy storage system for solar thermal applications
Study | PCM type | Thermal efficiency (%) | Exergy efficiency (%) | Charging/Discharging time (min) | Key observations |
|---|---|---|---|---|---|
Present study | Paraffin wax + Fatty acid | 85.2 | 47.5 | 240 | Cascaded PCM system improves efficiency |
Paraffin wax | 80.1 | 42.3 | 260 | Lower efficiency due to single PCM usage | |
Salt hydrates | 88.5 | 49.2 | 220 | Higher efficiency but stability issues | |
Organic-inorganic composite | 86.3 | 46.7 | 230 | Improved conductivity with composite PCM | |
Lauric-myristic acid | 81.7 | 44.1 | 250 | Moderate efficiency with good stability |
