This research studies the influence of using SiO2 nano-particles of 50nm in a Vapor Compression Refrigeration System (VCRS), along with Poly-alkylene Glycol (PAG) oil and R-134a mixed to create a nano-refrigerant. In this work, the nano-particles were performed in three different concentrations (0.1%, 0.3%, and 0.5%) and mixed with 200ml of PAG oil. AVCR system was built at the mechanical engineering department laboratory in Al-Qadisiyah University to study the Coefficient of Performance (COP) and the consumed energy by the compressor in the two cases of adding the nano-particles and using a pure refrigerant. The paper showed an increase in the system's COP from 2.3 to 2.81 when using a concentration of 0.5% of SiO2/PAG oil/R-134a, increasing the refrigeration effect and decreasing the consumed power.

In this day and age, cooling frameworks assume a significant part in gathering human requires, and consistent exploration should be finished by numerous analysts are attempting to work on the presentation of these frameworks. Here, an endeavor was made to further develop framework execution. Our present review on the trial examinations of TiO2 nanomotes scattered in polyalkylene glycol (PAG) oil with R134a cooling system, noticed that there is a lessening in the evaporator' glow, an improvement in the thermoactual properties of the nano-cooling system, and an improvement in the exhibition coefficient by (13.948%, 22.645%, 28.249% ) at the hotness heap of the evaporator 40 oC, and it is observed that the presentation coefficient improved (14.913%, 19.266%, 23.755%) at the hotness heap of the evaporator 50 oC and the exhibition coefficient improved (11.821%, 20.113%, and 24.358%) at the hotness heap of the evaporator 60 oC. Contrasted and unadulterated cooling system R134a. The exploratory results show that the hotness move coefficient of cooling system-based nano-fluid is more imperative than that of pure cooling system, very much like the coefficient of execution and when are utilized nano-cooling systems, power use is diminished by 3 to 20%, and the glow is decreased by (40 oc -17 oc).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
