Potential for Energy Utilization of Air Compression Section Using an Open Absorption Refrigeration System

Round 1

Reviewer 1 Report

The general structure of the paper is fine and it is well written. The Paper is of current interest and falls within the scope of the journal, however, there are the following suggestions without addressing them paper should not be accepted for publication:+-

Nomenclature should be added; units should be given in brackets.

The literature review needs to be updated, there are many studies published recently on this subject, especially in current years in reputed journals on the same subject.

The innovation/necessity of the present MS will not be reflected effectively.

Reviewer 2 Report

It is an interesting article. The OAR is promising for this application. Congratulation.

I did have some minor issue that you may want to address:

1) CAR is not defined in the text. In general, a nomenclature could help the understanding of the article with all symbols and acronyms used through it.

2) At some place (like on line 247), symbols appear above the text. In addition, represents is misspell on line 248.

When you calculate the power consumption (line 355), please indicate that you neglected the power consumed by ACT and WCT in both system with the justification. Considering it would reduce the payback period, so it is not an issue for the article’s acceptance.

Reviewer 3 Report

In this study, the authors proposed an open absorption refrigeration system to recover part of the waste compression heat while producing cooling capacity to further cool the compressed air. The self-utilization of the compression waste heat can significantly reduce the energy consumption for air compression and hence increase the energy efficiency. The maximum energy saving ratio of 8.05% can be achieved compared to conventional cooling system. Energy saving ratio ranges from 0.52-8.05% corresponding to the temperature range of 5-30oC and humidity range of 0.002-0.010 kg/kg.

This is a detailed study and worth publication after some minor revision.

1.       Thermoelectric cooling is very interesting technology for refrigeration. It is suggested to highly in the introduction, such as Journal of Materials Science & Technology 2022, 121, 256-262; doi.org/10.1002/smtd.202101235; Nature Materials 2021,  20,  454–461.

2.       In Figure 3, x- and y-axes should be labelled, such as Temperature (oC) and Pressure (Pa).

3.       Some unclear Figures should be replaced with high-resolution ones, such as Figure 1.

4.       What is the key technical, engineering, or scientific challenge for the integration of ACS and OCR systems? This can of great significance on highlighting the significance of this study and should addressed.
