The most commonly used refrigeration system operates on vapor compression system which consumes high amount of high-grade energy. Also its refrigerants cause environmental problems. Hydrocarbon refrigerants provides best alternative to the conventional halogenated refrigerants in terms of environmental impacts, efficiency and energy consumption. They also have zero ODP and very low GWP. Another way to improve system efficiency and to decrease energy consumption is introduction of nanoparticles in refrigerants (nanorefrigerants) and lubricants (nanolubricants).The aim of this paper is to present a comprehensive review about previous studies regarding application of hydrocarbon refrigerants, nanorefrigerants and nanolubricants in refrigeration systems. Previous results showed that hydrocarbon refrigerants and their mixture can be used as an alternative to halogenated refrigerants for the improvement of various factors such as environmental impacts, efficiency, and COP. Also addition of nanoparticles improves compressor performance, cooling speed and energy consumption.
