Special Issue Information
Dear Colleagues,
Heating and cooling in buildings contribute to approximately 15% of worldwide CO2 emissions, with a large share (approximately 3/4) taken by space heating and domestic hot water. Furthermore, industrial heating and cooling represent a massive portion of the global carbon footprint, with heat taking up to 37% of energy linked to CO2 emissions. The decarbonisation of heating and cooling, for both residential and industry applications, is therefore crucial in the prospect of reducing the carbon footprint, leading to substantial contributions towards a 45% reduction of CO2 emissions by 2030 as well as net zero emissions by 2050. The development of highly efficient heat pumps (systems with a higher coefficient of performance or COP) will play a vital role in that respect. This Special Issue is dedicated to such advanced systems linked to the following:
- Conventional vapor compression heat pumps.
- Thermally driven heat pumps.
- Thermal transformers.
This covers experimental and theoretical work including the modeling of thermodynamic cycles and systems or components, as well as proof of concept or demonstration prototypes. The systems or cycles operating with environmentally friendly refrigerants such ammonia (R717), water (R718), carbon dioxide (R744) and hydrocarbon natural refrigerants are desirable but not compulsory. Overall, refrigerants with zero or near zero ozone depletion potentials (ODPs) and low global warming potentials (GWPs) are preferred. The delivery temperatures cover the following ranges:
- 40 °C to 80 °C (for domestic heating, low-temperature district heating and low-temperature industrial processes like paper re-inking, food concentration or bio-chemical reactions).
- 80 °C to 200 °C (for district heating and various industrial processes including food processing, paper drying and steam production).
- Above 200 °C (for various high-temperature industrial processes including high-temperature steam production).
The main objective of this Special Issue, “Advanced Energy-Efficient Heat Pump Systems”, is to gauge the current progress of research and development.

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. 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.
