“…In the works of Sung et al [23,24] authors developed and empirically modelled a meso-scale vapour-compression system intended for various small-scale cooling devices e.g., heat pipes. System with dimensions of 60 × 60 × 100 mm 3 and maximum cooling capacity of 80 W kept the temperature of the heat source around 46 °C with average COP 2.15 at evaporating and condensation temperatures of 27.4 °C and 60 °C, respectively.…”

Thermal management is becoming more challenging due to the increasing compactness and computational power of appliances. Affordable and efficient solutions include active liquid cooling methods, thermoelectric cooling, and the use of heat pipes. From these, vapour-compression technologies achieve the highest power density. However, the downscaling of vapour-compression for cooling of personal computers or workstations is rather problematic from several different reasons. The first problem concerns the low second law efficiency of miniature vapour-compression systems. The second problem concerns the available space occupation of such a cooling system. Moreover, miniature and high-power density condensers and evaporators have not yet been adequately researched and developed to date. In this review, we present several vapour-compression refrigeration systems that are based in some way on the miniaturisation of systems or individual components – evaporators, condensers, and compressors. These are presented and compared in terms of cooling power, COP, and the second law efficiency. At the end of the manuscript, guidelines for future improvements and the implementation of miniature vapour-compression systems are presented.

“…The authors found that ambient temperature strongly affects the performance of the system; however, under different scenarios, they managed to keep the temperature below 120 °C for an ambient temperature of 55 °C. A very singular meso-scale VCR system design stacked a rotary vane-type compressor, a film-wise condenser, an expansion nozzle, and a microchannel evaporator, similar to the scheme shown in Figure 15 [57]. Additionally, three heat pipes were incorporated with the condenser and the evaporator was designed by the Taguchi method to further increase heat transfer.…”

The study and development of miniature refrigeration and climate conditioning systems based on vapor compression for small-scale applications have received wide interest in recent years due to their advantages compared with other available technologies, both active and passive. This paper identifies different applications and areas of opportunity, including electronic components and personal cooling, where small-scale vapor compression refrigeration systems are anticipated to play a key role in technological development. This paper presents the current state of the art, including applications, component designs, operating conditions, experiments, published results, etc. to describe the current status of small-scale vapor compression refrigeration and illustrate a perspective for the future of this technology.

“…The system achieved a cooling capacity of 40 W and a COP of approximately 2.25. Sung et al [10] recently developed a very compact MVCR system with dimensions of 60 mm × 60 mm × 100 mm, whose the cooling capacity was 80 W with a COP of 2.15. Trutassanawin et al [11] built a miniature R-134a system using a variable speed DC rotary compressor.…”

“…Apart from the results obtained for the different types, the three alternatives manage to generate a cooling capacity of 110 W, which is similar to the power to be obtained in this project. The work carried out by Taijong Sung et al [10] also uses microchannel as the structure for the condenser and evaporator, the latter having fins. The cooling capacity of this system is 80 W. In a similar way, the heat exchangers designed by Ricardo et al [26] use the plate HXs typology with different routes, (a) serpentine (b) nested (c) parallel with fins.…”

This research aims to enter the miniature refrigeration machine sector with the objective of designing a small scale unit while maintaining a competitive coefficient of performance (COP), comparing with a Peltier plates system. To this end, a research of the current technology was carried out in order to obtain indicative values on the scales that were being worked on and their application. After the previous research, a refrigeration cycle was designed in EES (engineering equation solver). From this design, different conclusions were obtained: (1) The correct sizing of the compressor revolutions together with its displacement is crucial for the equipment to be able to provide the desired cooling capacity. (2) In order to obtain the desired cooling capacity in the microscale refrigeration system, the heat exchangers must have fins. (3) Of the analysed refrigerants, R600a is the best choice, as it shows favourable characteristics (high COP and low compression ratio) when working in this type of cycle.
