Special Issue Information
Dear Colleagues,
Refrigeration machines and heat pumps are energy-conversion systems that operate based on inverse thermodynamic cycles. Refrigeration machines and heat pumps are core systems in air conditioning, cooling, freezing, artificial heating, and thermal management applications across residential, commercial, and industrial sectors. Due to the high energy consumption associated with these systems, improving their thermodynamic performance is a major research and engineering goal. Conventional performance indicators (the first law of thermodynamics)—the coefficient of performance (COP) is the key indicator—are applied to the overall system. To address the irreversibilities within system components, entropy analysis (the second law of thermodynamics) should be applied. Exergy analysis, as a combination of the first and second laws of thermodynamics, offers a more comprehensive tool for evaluating the performance of the overall system and its components. Optimizing refrigeration and heat pump systems using entropy and exergy concepts involves reducing entropy generation and minimizing exergy destruction through improved component design and operating strategies. This includes optimizing compressor efficiency, enhancing heat-exchanger effectiveness, selecting environmentally friendly and thermodynamically suitable refrigerants, and optimizing temperature and pressure levels. Exergy-based analysis and optimization further support decision-making by linking thermodynamic performance with economic and environmental considerations.
This Special Issue aims to showcase new improvements and optimizations of refrigeration machines, heat pumps, and thermodynamic methods.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
