Time-temperature control can lead to mal-defrost under variable operating conditions.
“In addition, time-temperature control can lead to mal-defrost under variable operating conditions [64].”
As the frost layer thickens, the heating capacity of ASHP can decrease by approximately 30-57%.
“and the heating capacity can decrease by approxi mately 30 -57 % [35 -37].”
From Enhancing heat-exchanger performance in frost conditions via superhydrophobic surface modification (2024) · cites this paper as [35]
Compared to the research conducted by scholars [35,40-44,46,87,88], this approach considers the overall improvement of the frosting and defrosting process for the ASHP, effectively combining proactive defrosting with efficient defrosting.

From Enhancing heat-exchanger performance in frost conditions via superhydrophobic surface modification (2024) · cites this paper as [35]
Delay after critical level caused 17.4% reduction in COP, and defrosting in absence of frosting caused 4.2% reduction in heating efficiency.
“The former caused a 17.4% reduction in COP, and the latter a 4.2% reduction in heating efficiency.”

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.
