Effect of Shelf Aperture Ratio on the Temperature Distribution of an Open Refrigerated Display Cabinet
Round 1
Reviewer 1 Report
The submitted paper is dealing with study on Effect of shelf aperture ratio on the temperature distribution of an open refrigerated display cabinet. The study is common. However, the data produced is very useful for the application and references in designing and improving the open refrigerated display cabinet efficacy.
However, from my point of view there is a major error in the Materials and Methods section that makes this paper should not be accepted as it is. Due to this error also, it is impossible for the reviewer to understand the result, discussion, and the conclusion of this paper. And there are a lot of doubt, questions and unnecessary assumption that the reviewer should do in order to understand the paper, which is not a proper way to review a result and finding of academic research.

Dear Editors,
Thank you for your letter and for the Reviewers’ comments concerning our manuscript entitled “Effect of shelf aperture ratio on the temperature distribution of an open refrigerated display cabinet” (Ref: applsci-1925263). Those comments are all valuable and very for revising and improving our paper, as well as the important guiding significance to our researches. We have studied comments carefully and had made correction which we meet with approval. We tried our best to improve the manuscript and made some changes in the manuscript. These changes will not influence the content and framework of the paper.
Kind regards,

Please revised the whole section properly, especially from line 191-205.
We are sorry for the content, which belongs to the template downloaded from Applied Science website, and we have removed it out and checked the whole paper to avoid this mistake.
Figure 5 – Overall uniformity; no explanation on the formulation in methodology (section 2). (Usually presented using the standard deviation with no unit (ratio)).
We are sorry for lacking the calculating formula of overall uniformity and causing misunderstanding to you. We have added the formal to the paper, which was marked in yellow.
Difficult to continue reading and understand the rest of the paper due to lack/error of explanation in section 2.
This paper studies the temperature distribution in the display cabinet by designing different aperture ratio of shelves. In addition to the distribution parameters of temperature, the corresponding energy consumption, represented by "Temperature maintenance coefficient" is also considered, which provides more references for the selection of opening rates of shelves. The influence of different shelf aperture ratios on the periodic temperature fluctuation, average temperature, temperature non-uniformity coefficient, and temperature maintenance coefficient inside the cabinet is studied by means of experiments with pork.
We have added or modified content in section 2 for better understanding of the paper, and we also added the research route in figure 2(a), which was marked in yellow.

Line 66-68 – please explain the relevancy of this sentence to this paper.
This sentence explains the origin of the design of the cold air curtain, in order to better elaborate the purpose of this test design. After discussion among all the authors, it was decided to delete this part for it was not too relevant to this paper.
Line 130-133 – It is advised, the sequence of the uncertainty/tolerance of the measuring device should follow the sequence of the measuring properties. E.g., temperature, relative humidity (uncertainty of temperature, followed by uncertainty of relative humidity).
Thanks for your sincere advice that the measuring device should follow the sequence of the measuring properties. The sequence has been modified and it was marked in yellow.
Line 184-190 – abbreviation in formula and in the sentence not matched. (Not being formatted and checked properly). E.g., Ti should be written as T subscript i (Ti)
The format has been modified and it was marked by yellow. We also check the whole paper to avoid the mistake.
Line 216 - …when the refrigeration unit opens, …; what do the author means by that phrase. The electric circuit is open or the system is on? Please use a proper/universal term.
We are sorry for causing mistakes in comprehension, the “refrigeration unit opens” means “the system is on”, we have modified the paper and marked in yellow.

Reviewer 2 Report
The paper titled "Effect of shelf aperture ratio on the temperature distribution of 2 an open refrigerated display cabinet" is written very well. The results outcome will be quite useful for the refrigeration industries.
Before accepting the paper the following comments can be answered,
- From the given figures, it is not very much clear about the aperture ratios of 12.5%, 25%, 50%, and 90%. It would be better, if the authors can show the figure for each one.
- lines 191 to 205 seems to be comments given by the reviewer. I guess it should be kept at the end.
- what is the comment of authors' on the repeatability of the experiments?
- what is the error analysis of the experiments?
- Which of the two "Non-uniformity coefficient" and "Temperature maintenance coefficient" has more significance in terms of the objective?
- Which one of the two "overall uniformity" and "average temperature" has more significance in terms of the objective?

- From the given figures, it is not very much clear about the aperture ratios of 12.5%, 25%, 50%, and 90%. It would be better, if the authors can show the figure for each one.
The shelf design of different aperture ratio was added as appendix at the end of the paper, and the relevant statement of design was introduced in line 138-147.
- lines 191 to 205 seems to be comments given by the reviewer. I guess it should be kept at the end.
We are sorry for the content, which belongs to the template downloaded from Applied Science website, and we have removed it out and checked the whole paper to avoid this mistake.
- what is the comment of authors' on the repeatability of the experiments?
The experiment was repeated three times for each factor level, and the relevant statement was introduced in line 167-168, which was marked in yellow.
- what is the error analysis of the experiments?
The experiment was repeated three times for each factor level, and the temperature, time were calculated by the average of three times, and the error line of standard deviation was added in the figures.
- Which of the two "Non-uniformity coefficient" and "Temperature maintenance coefficient" has more significance in terms of the objective?
This paper studies the temperature distribution in the display cabinet by designing different aperture ratio of shelves. In addition to the distribution parameters of temperature, the corresponding energy consumption, represented by "Temperature maintenance coefficient" is also considered, which provides more references for the selection of opening rates of shelves. Therefore, "Non-uniformity coefficient" has more significance in terms of the objective than "Temperature maintenance coefficient".
- Which one of the two "overall uniformity" and "average temperature" has more significance in terms of the objective?
"overall uniformity" represents the difference between the highest temperature and the lowest temperature calculated by formula (2) , which represents the temperature deviation; "average temperature" represents the cooling and temperature maintain efficiency, therefore, "average temperature" has more significance in terms of the objective than "overall uniformity".
