Global warming is a major environmental concern, which significantly impacts ecological
systems and the safety of coastal cities. To address global warming, effective methods must …

Several environmental protection policies have been enforced restricting working fluids with
high global warming potential (GWP) values used in many types of refrigeration and heat …

High temperature heat pumps (HTHPs) have a great potential to improve industrial
processes with thermal demand through industrial waste heat recovery and revalorization …

High temperature heat pump is a promising solution for efficient high temperature heat
supply. However, the poor performance when it operates in large temperature lift hinders it …

The industrial sector demands novel sustainable energy systems to advance in its
decarbonisation and meet the targets of the Paris Agreement for the climate change …

Power generation systems recovering waste heat, such as Organic Rankine Cycles (ORC),
cannot work efficiently when the highest temperature ranges between 100° C and 85° C. For …

In response to the COVID-19 pandemic, some vaccines have been developed requiring
ultralow-temperature refrigeration, and the number of these freezers has been increased …

This paper builds a cascade refrigeration cycle (CRS) system for the requirement of
producing ultra-low temperature of− 80 to− 50℃. Taking R404A/R23 CRS as an example …

Inspired by the principle of cascade energy utilization, the concept of cascade-heating is
introduced, and five layouts of cascade-heating high temperature heat pump (HTHP) …

Nowadays, a high amount of industrial thermal energy is still lost due to the lack of
competitive solutions for energy revalorization. Facing this challenge, this paper presents a …
