In terms of physics, the operating principle of a heat pump is the same as that of a refrigerator: Moving heat from a low-temperature level to a high-temperature level. If in a refrigerator, the cold at lower temperature is used, and a heat pump provides heat at temperatures high enough for heating. Refrigeration and heat pump systems use various types of thermodynamic processes based on vapor compression, sorption, or caloric technologies.
Today, heating and cooling account for nearly 50% of global energy demand. It is, therefore, essential to make the thermodynamic processes for refrigeration and heat pump systems as energy-efficient as possible. The latest research into heat pump and refrigeration cycles has focused on improving the existing solutions and developing new, alternative, more sustainable technologies.
The purpose of this Special Issue is to highlight the results of research on how to increase the efficiency of thermodynamic processes for heat pump and refrigeration systems. While room remains for further efficiency improvements of classical thermodynamic processes, it is precisely new heat pump and refrigeration technologies that most of the major new discoveries and applications in thermodynamics are expected to yield.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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-blind 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 1800 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.
