About this Research Topic
To meet the requirements of refrigeration, heating and cooling for residential, industrial, commercial and public applications, massive fossil fuels have been consumed and emit excess greenhouse gases, which leads to the disruption of the natural carbon cycle path of the ecosystem. In order to satisfy the inherent demand of sustainable development, the conventional energy structure is changing, and the utilization of renewable energy such as solar energy, wind energy, and geothermal energy, etc. is increasingly attracting attention from all over the world. The refrigeration, heat pump and air conditioning system account for a large proportion of global carbon emissions due to the energy consumption and refrigerant leakage. Consequently, advanced technologies should be developed to achieve the goal of carbon neutrality in fields such as refrigeration, heat pump and air conditioning systems as well as the systems coupled with renewable energy sources.
A large number of research works have been conducted by developing a range of technological innovations from component to system level, as well as combining them with renewable energy, aiming to make the refrigeration, heat pump and air conditioning system more efficient, environmentally friendly and economical. The adoption of eco-friendliness and energy-saving characteristics among those fields is mandatory in order to mitigate the contemporary environmental challenges and to respect the different regulations on the progressive ban of hydrofluorocarbons (HFCs). Even so, to improve the performance of the whole system, many technical challenges still need to be overcome. For example, how to realize the safe and efficient utilization of the environmentally friendly refrigerants, how to optimally design the key component and system configuration, and how to reasonably combine the system with renewable energy, etc. Therefore, this Research Topic focuses on theoretical and experimental research work on refrigerant selection and performance, component optimum design, advanced system configuration development, system integration with renewable energy, etc., aiming to explore promising solutions and achieve the demand for sustainable development and carbon neutrality.
The topic welcomes submissions of Original Research articles, Review articles, and other papers. Suggested topics include, but are not limited to:
(1) Refrigerant selection and performance evaluation (thermodynamic, thermochemical, heat transfer, safety, etc.)
(2) Heat transfer enhancement of refrigeration, heating, cooling, or power generation system
(3) Natural refrigerant, eco-friendly refrigerant, or mixture refrigerant
(4) Modeling, optimum design, manufacturing, and testing of key components
(5) New system configuration development, modeling, evaluation, prototyping or field testing, applications
(6) Heating or cooling system for special scenarios (high temperature or low temperature applications)
(7) Expansion of the refrigeration/heat pump technology to varies fields (electric vehicles, integrated heating and cooling in industrial and commercial situations, etc.)
(8) New technology of refrigeration, heating or cooling: breakthrough and reform measures
(9) District heating or cooling with heat pump and/or renewable energy
(10) Complicated energy systems with refrigeration, heat pump, energy storage, power generation, renewable energy collection, etc.
