Supercooling Stability of Sodium Acetate Trihydrate Composites in Heat Storage Units

Mark Dannemand from the Technical University of Denmark created this dataset. It describes an experiment with 10 commercial heat storage units containing 35 kg of sodium acetate trihydrate composite. Multiple heating and cooling cycles were performed, monitoring spontaneous solidification over 3-day storage periods at various discharge inlet temperatures.

Use Cases

• Predict spontaneous crystallization risk based on discharge temperature conditions.
• Compare the performance stability of different commercial heat storage unit designs.
• Model heat release profiles for supercooled sodium acetate trihydrate composites.

Strengths

• Experiment involved 10 distinct commercial heat storage units.
• Test cycles used specific, reported inlet temperatures of 87°C, 14°C, 22°C, 28°C, and 35°C.
• Data is based on a 3-day storage period observation for each cycle.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
