Experimental assessment and semi empirical estimation of frost accretion—A case study on a spine-finned inverted-V tube array evaporator

Present work focuses on frost accretion in a spine-finned inverted-V tube array evaporator. An experimental evaluation was performed using standard issue, vertical top-mount, 18 cubic feet, 0.5 m 3 , refrigerator. Evaporator temperature distribution, inner airflow velocity, and relative humidity were measured to account for convective phenomena influencing distribution. Frost formation the surface of evaporator visualized thermal microscopic imagery. The images processed machine vision algorithm measure thickness. Complementarily, density vapor mass transfer computed available correlations. estimation function derived from compiled data semi empirical approach, i.e., direct measurements thermophysical substance properties. resulting mathematical expression estimated rate within an error expectancy, RMSE, 0.1479 displayed goodness-of-fit, R-Squared, 0.9029. Based these results, estimation, is proposed as viable approach construct adequate limits new predictions, vis-à-vis performance, ultimately reducing appliance energy consumption via implementing more effective control strategies regarding internal defrosting.
