Abstract
The use of technological innovations to obtain more efficient refrigeration systems is increasingly frequent. Thereunto control and automation methods were improved, components were improved, more efficient and sustainable refrigerants were produced and nanofluids were developed. The dispersion of nanoparticles, both in the coolant and in the lubricating oil, in a cooling system is considered a prospective method to increase the efficiency of the system. However, claims about nanoparticles based on the physical phenomena that affect the vapor compression refrigeration system (SRCV) are limited in the literature. The methodology applied for the preparation of this work, were stratified studies through the platform: Scopus. This research combined bibliometric techniques and a systematic review of the literature. One of the criteria chosen in the work's methodology was the application of search filters (strings) with the aim of refining the study and achieving more rigorous results. Another selection criterion for the work was the use of relevant international journals. Indicators such as coefficient of performance and cooling capacity are always being mentioned in studies. The time range used was the period from 1990 to 2022 and it was possible to reach several publications on the subject, revealing the researchers' interest in dealing with this topic, which remains relevant and current. The literature review was inserted to investigate the performance of refrigeration systems by vapor compression with the use of nanoparticles. Through the analyzed studies, it was noticeable that the insertion of nanoparticles in refrigerant fluids or lubricating oil are positive for the system since the application of this technology allowed improvement in the analyzed parameters.
