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.

“…water) to absorb the solar thermal energy from a PVT panel and cycle it to a heat exchanger to transfer heat to a heat pump cycle or store in a water tank [18,21]. The water tank acts as a heat source for the heat pump [18,21]. Besgani et al [22] conducted an experimental study on a dualsource solar-assisted IEPVT/HP system in Milan, Italy, on a detached prefabricated building.…”

This work investigates a solar combined heat and power systems based on hybrid photovoltaic-thermal heat pump systems for the simultaneous provision of space heating and electricity to residential homes. The analysed system connects a photovoltaic-thermal (PVT) panel, through a PVT water tank, to a heat pump. The study is based on quasi-steady state heat transfer and thermodynamic analysis that takes incremental time steps to solve for the fluids temperature changes from the heat pump and the solar PVT panels. The effects of solar irradiance, size of the water tank and the water flow rate in the PVT pipes (laminar and turbulent) on the performance of the system are analysed. Particular focus is made towards the efficiency (electrical and thermal) of the PVT and the COP of the heat pump. Results show that the minimum COP of the heat pump is 4.2, showing the high performance of the proposed hybrid system. Increasing the water flowrate through the PVT panel from 3L/min (laminar) to 17L/min (turbulent) increases the PVT's total efficiency (electrical + thermal) from 61% to 64.5%. Increasing the size of the PVT water tank from 1L to 100L, increases the total efficiency of the PVT panel by 6.5%.

“…The study found that the system with batteries and thermal storage could reach 89% and 88% electricity selfconsumption, respectively. Another European study was carried out by Hazi and Hazi [79] where a computer model was introduced to investigate the efficiency and effectiveness of PV/T enhanced DX-SAHP systems for various high-temperature industrial applications under the weather conditions of Bacau, Romania. Similar to the research by Thygesen and Karlsson [77], [78], the numerical model developed by Hazi and Hazi [79] also lacked a robust validation and uncertainty analysis to ensure accuracy of the results.…”

This paper presents a comprehensive review on developments and advances of Solar Assisted Heat Pump technology reported in 21 st century. Combination of thermal and photovoltaic solar collectors with heat pumps has been widely used in recent decades for simultaneous heat, hot water and power generation for a broad range of applications, from providing domestic and commercial buildings with heat and power to manufacturing and agricultural applications. This review critically analyses the research reported in past two decades with particular attention to the works with substantial importance for future development of the technology. Four distinctive investigation periods were considered and key developments and dominant technologies at each period were reported. The main novelties and breakthroughs in solar assisted heat pump technology, as identified by this review, are: (1) The ban on R-12 refrigerant which lead to dominance of R-134A refrigerant for a wide range of systems and applications, (2) Increasing interest in Solar-assisted Ground Source Heat Pumps following the technological advances that made the utilization of such systems cost effective, (3) Advances in numerical analysis methods and use of Artificial Intelligence applications in investigating performance and effectiveness of various systems, and (4) Integrating the Photovoltaic/Thermal collectors with heat pumps for simultaneous heat and power generation resulting in improved performance and reliable operation of systems under severe operating conditions. Highlights• Four distinctive investigation periods from 2000 to 2020 are considered • Key developments and prevailing breakthroughs at each period are presented • Advantages and shortcomings of each study are discussed • Different types of SAHPs, applications, and performances are investigated
