Special Issue Information
Dear Colleagues,
Refrigeration and heat pumps impact the end-use energy consumption of residential, industrial and commercial sectors. Air conditioning and refrigeration are responsible for about 20% of the global energy demand, which is expected to more than double by 2050.
The global warming potential (GWP) of working fluids customarily employed and the energy efficiency of refrigeration and heat pump systems are responsible for the non-negligible greenhouse gas (GHG) emissions in the atmosphere, and have prompted regulatory actions, e.g. by the European Union for their phaseout. Similarly, the energy efficiency of components and refrigeration systems must increase to limit energy consumption and GHG emissions associated with plant operation.
These issues pose significant challenges to the refrigeration industry, such as:
- the search for new working fluids able to substitute high-GWP refrigerants;
- the safety aspects associated with the mostly flammable alternatives to high-GWP refrigerants;
- the expected growth of air conditioning demand in sunbelt Countries and the subsequent increase in GHG emissions;
- the increase in energy efficiency of components and refrigeration and heat pump systems;
- the increasing market demand for low-cost and limited maintenance devices.
The topics to be addressed in this Special Issue on “Advances in Refrigeration and Heat Pump Technologies” include but are not limited to:
- Energy efficiency of refrigeration components and systems for domestic, residential, industrial and commercial applications;
- High-temperature heat pumps for industrial applications;
- Cascade systems for combined cooling and heating;
- Demand side management;
- Integration with renewables;
- Digitalisation, smart control and operations;
- Alternatives to vapour compression systems;
- Environmental impact of refrigeration and heat pump technologies;
- Alternative and low-GWP working fluids;
- Natural refrigerants and their applications;
- Safety issues and risk assessment for flammable refrigerants.

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. Energies is an international peer-reviewed open access semimonthly 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.
