Condensation Heat Transfer Data for R404A, R448A, and R452A in a 4.7 mm Tube

Experimental data on flow condensation for refrigerants R404A, R448A, and R452A collected at Oregon State University. The dataset reports local condensation heat transfer coefficients and thermodynamic qualities measured across seven segments of a horizontal 4.7 mm internal diameter copper tube. Experiments varied mass fluxes from 100 to 800 kg m^(-2) s^(-1) and saturation temperatures of 40, 50, and 60 degrees Celsius.

Use Cases

• Modeling condensation heat transfer coefficients based on refrigerant type, mass flux, and quality.
• Comparing the thermal performance of R404A, R448A, and R452A refrigerants under varying operating conditions.
• Validating computational fluid dynamics (CFD) simulations of in-tube condensation using experimental segment data.
• Analyzing the relationship between coolant-side energy balances and local heat transfer coefficients.

Strengths

• Data includes three distinct refrigerants (R404A, R448A, R452A) for comparative analysis.
• Experiments cover a defined range of mass fluxes (100 to 800 kg m^(-2) s^(-1)) and three saturation temperatures (40, 50, 60°C).
• Local measurements are provided for seven distinct segments of the test section.

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.
