Experimental Facility for the Study of Liquid Overfeed Fin-and-Tube Evaporators: Validation of Numerical Models
An experimental facility specially designed for the study of liquid overfeed fin-and-tube evaporators was developed. It is intended for the experimental validation of a detailed liquid overfeed evaporator model, permitting testing as either a part of the refrigeration system or in a loop without a compressor. The facility can also be used for the experimental evaluation of refrigeration system performance-prediction models.
A detailed description of the facility and its instrumentation, emphasizing the data uncertainty analysis and the verification techniques, is provided.
A method for experimentally estimating the systematic uncertainties in the measurement of the temperature sensors after calibration, accounting for the whole signal path, is also presented.
Results from a detailed numerical model of liquid overfeed evaporators, developed for design optimization, were compared with the experimental data. Six well-known correlations for the two-phase flow heat transfer coefficients were studied in order to assess their influence in the overall evaporator performance prediction.
