There must be an optimal time between two consecutive defrost operations.
“since Zakrzewski [20] pointed out that there must be an optimal time between two consecutive defrost operations.”
From Optimal design of fan-supplied tube-fin evaporators subjected to frosting conditions aiming at minimum energy consumption (2018) · cites this paper as [20]
Zakrzewski's correlation underestimates the optimum runtime and overestimates the cooling cycle efficiency compared with the new defrost efficiency correlation.
“One can see that the later underestimates the optimum runtime and overestimate the cooling cycle efficiency as it provides higher figures for the defrost efficiency in the range of mass-to-surface area under analysis”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
