Sustainable design of hydrocarbon refrigerants applied to the hermetic compressor
… (HFCs) such as R134a which has a zero ozone depletion potential (ODP). The use of HFCs has also come under scrutiny as they have high global warming potential (GWP) and inferior thermodynamic and lubricating properties and have been replaced by hydrocarbon (HC) refrigerants such as …

Experimental investigation and mathematical modelling of dynamic equilibrium of novel thermo-fluids for renewable technology applications
… problems. Solar thermal energy has a potential to diminish the dependency on fossil fuels and reduce CO2 emissions in which solar radiation is converted to heat via a thermal fluid for power and heat generation. Medium and high-temperature solar thermal systems where concentrated …

Design, Testing And Controls For Air Source Heat Pump System In Cold Climates Using Natural & Conventional Refrigerants
… to the HFC refrigerants. R744 has zero ozone depletion potential (ODP) and a global warming potential (GWP) of 1 which is almost thousand times lower than the HFC refrigerants.</p> <p>In this study, air source heat pump systems with natural refrigerant and conventional refrigerant R410A …

Scuffing and wear of engineering materials under different lubrication regimes in the presence of environmentally friendly refrigerants
… non-flammable and non-toxic, but posses a high ozone depletion potential (ODP). Despite the fact that HFCs have zero ODP, they were found to have a high global warming potential (GWP) being considered one of the green house substances to be banned by the Kyoto agreement. The interest for long …

Assessment of the environmental acceptability of refrigerants by discrete mathematics: cluster analysis and Hasse diagram technique
… is their ability to deplete the stratospheric ozone layer, quantified by the ozone depletion potential (ODP). Some of the first replacements mooted were hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs), which contribute to the global warming, quantified by the global warming …
