The increasing need for thermal comfort has led to a rapid increase in the use of cooling
systems and, consequently, electricity demand for air-conditioning systems in buildings …

During the last decade, many industrial and medical applications have shown a requirement
for low-temperature-cooling usage (from− 40 to− 80° C), which cannot be efficiently obtained …

A comprehensive experimental study on the ejector and cooling performances of a
transcritical CO 2 ejector-expansion system is presented. The ejector performance of the …

Recently, the transcritical CO 2 refrigeration cycle shows advantages in supermarket
refrigeration applications. However, there is high expansion work recovery potential due to …

An experimental study was conducted on vapor compression refrigerators using R134a
refrigerant for the purpose of achieving energy recovery and decreasing the effects of …

This paper assesses the exergetic performance inside transcritical CO 2 ejector refrigeration
system integrated with thermoelectric subcooler (EJE+ TES) through conventional and …

A novel closed-loop transcritical CO 2 air-source heat pump drying (HPD) system with a
relatively simple structure, higher drying temperature, and internal heat exchanger (IHX) for …

In the present paper, a multi-target temperature ejector-expansion subcooler vapor-injection
refrigeration cycle is proposed in order to improve the performance of natural fluid CO 2 …

Supersonic two-phase flow of CO 2 in an ejector was investigated in flow visualization
experiments. The ejector was installed in a transcritical CO 2 ejector-expansion refrigeration …

In this paper, an improved thermodynamic model for the design of a small two-phase ejector
is proposed by using the constant-pressure mixing modeling method. Particularly, the mixing …
