Heat Pumps for the New Generation of Sustainable Buildings: Future Trends and Aspects

Dear Colleagues,

Heat pumps are efficient heat generators which can satisfy entirely the thermal demands of buildings’ space heating, space cooling and domestic hot water production by means of a single device. Moreover, this technology exploits a significant share of renewable energy from external sources (e.g., air, water, ground) and, for this reason, can contribute significantly to reaching the ambitious cuts in greenhouse gas emissions imposed by current policies. For these reasons, there is no doubt that we will soon see a capillary use of heat pumps in buildings to boost the decarbonization of the actual stock.

From a holistic point of view, the integration of heat pumps in existing or newly built HVAC systems, new environmentally friendly refrigerants, and optimization of the heat pump thermodynamic configuration are some of the open challenges that need to be answered to maximize the exploitation of renewable energy sources. This Special Issue aims to present and disseminate the most recent advances in heat pumps and heat pump applications, giving new insights related to the theory, design, modeling, application, control, and field monitoring of all types of heat pumps.

Topics of interest for publication include, but are not limited to:

• Research and development on heat pump refrigerant cycle;
• New environmentally friendly refrigerants;
• Recent advances in heat pump systems and components;
• Industrial and high-temperature heat pumps;
• Hybrid heat pump systems;
• Sorption and non-traditional heat pump systems;
• Simulation-assisted design and optimization of heat pumps and heat pump applications.

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.
