“…However, the COP of the system strongly depends on the ejector performance [113] and, therefore, detailed models for the off-design of the component should be developed along with an optimization of the ejector geometry [132]. When considering hot climates, in which the condenser has a lower efficiency, the solution proposed by Sirwan et al [204] may enable the system to perform well. A summary of the EAbRS studies is presented in Table 8.…”

“…These concerns can be relieved with additional research on new mixtures of HCs and HFCs [8]. Another working fluid that has been studied is ammonia (R717) [106,130,139,144,146,149,157,192,[202][203][204][205] for its low cost, high performance and more favorable thermodynamic properties, and it does not create environmental problems. However, it likely will remain restricted to industrial applications, as it is unsuitable for domestic use due to its toxicity [13].…”

“…As a consequence, COP is 30% higher than a conventional single-effect cycle. Sirwan et al [204] proposed using a flash tank between the condenser and the evaporator to improve both ω and the cooling effect. In particular, the study is focused on the case of the use of solar energy, where the performance is limited by the solar collector (heat source) and the range of the high ambient temperature COP of the modified cycle (0.49-0.86) is higher compared to that of a combined absorption-ejector cooling cycle (0.42-0.75) and of the basic absorption cycle (0.18-0.575).…”

a b s t r a c tThe 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. Heat-driven ejector refrigeration systems appear to be a promising alternative to the traditional compressor-based refrigeration technologies for energy consumption reduction. This paper presents a comprehensive literature review on ejector refrigeration systems and working fluids. It deeply analyzes ejector technology and behavior, refrigerant properties and their influence over ejector performance and all of the ejector refrigeration technologies, with a focus on past, present and future trends. The review is structured in four parts. In the first part, ejector technology is described. In the second part, a detailed description of the refrigerant properties and their influence over ejector performance is presented. In the third part, a review focused on the main jet refrigeration cycles is proposed, and the ejector refrigeration systems are reported and categorized. Finally, an overview over all ejector technologies, the relationship among the working fluids and the ejector performance, with a focus on past, present and future trends, is presented.

“…In his model the secondary flow of the ejector is directly linked with the low pressure streamline of the evaporator. Sirwan et al [34,35] showed that the performance of a combined absorption-ejector cooling cycle can be enhanced further by adding a flash tank to the cycle. However, some limitation on the ejector efficiency is …”
