Abstract Vapor Compression Refrigeration Systems (VCRS) are widely used to provide
cooling or freezing for domestic/office buildings, supermarkets, data centres, etc., which …

This paper presents recent developments and state of the art for transcritical CO2 cycle
technology in various refrigeration, air-conditioning and heat pump applications. The focus …

With carbon emission levels on the rise, rapid and far-reaching action is needed to
counteract global warming. Among many available strategies, CO 2 is nowadays more and …

The organic rankine cycle (ORC) as a bottoming cycle to convert low-grade waste heat into
useful work has been widely investigated for many years. The CO2 transcritical power cycle …

Supercritical CO2 power cycles have been deeply investigated in recent years. However,
their potential in waste heat recovery is still largely unexplored. This paper presents a critical …

Since its resurgence as a refrigerant in the 1990s, Carbon Dioxide (CO 2) has grown in
popularity and breadth of application. Its negligible global warming potential (GWP) …

This study proposed an improved CO 2 heat pump system for electric vehicles by
introducing the concept of two stage compression with intermediate cooling. A coefficient of …
