The objective of this work is to provide a literature survey on the research attempts made in
the field of ejector refrigeration systems and the studies made on the ejector as a …

As a highly efficient thermodynamic cycle formed by pure natural fluid and using
aerothermal energy, transcritical CO 2 technology has huge advantages in terms of energy …

Visible signs of climate change call for urgent actions on food retail industry, since such a
sector is characterized by an abundant carbon footprint. Being CO 2 (or R744) recognized …

This paper investigates the integrated and state-of-the art features of CO 2 trans-critical
booster systems. The main objective is to identify the most promising solutions in terms of …

Ejector refrigeration has not been able to penetrate the market because of the low coefficient
of performance and because of the high influence of ejector performance on the efficiency of …

The use of an expansion energy recovery ejector has been given great concern owing to
virtues of no moving elements, cost-effectiveness, high reliability and comparable efficiency …

A novel hybrid solar energy and waste heat driving absorption subcooled carbon dioxide
(CO 2/R744) booster refrigeration system (SE+ WH) is proposed to improve the energy …

The performance of fixed ejector is limited by working conditions, so it is difficult to meet the
operating requirements of electric vehicle heat pump system under varying conditions and …

The rise in the popularity of heat pumps should be accompanied by the increase in the
utilization of environmentally-safe working fluids. To push for wider uptake of hybrid heat …

Refrigerants bearing high global warming potential (GWP) and ozone depletion potential
(ODP) were outlawed or facing time‐beared permission under the Montreal (1987), Kyoto …
