HFCs (Hydrofluorocarbons) are one of the most widely used refrigerants worldwide. But,
HFCs are heading towards complete phase out in the near future due to environmental …

Prolonged use of environment unfriendly refrigerants in high-grade energy systems has
resulted in increased greenhouse gas emissions and ozone layer depletion. This has …

Abstract In 2014, the Directive 517/2014 was introduced by European Parliament to reduce
the use of high-GWP greenhouse gases in the European area in order to limit global climate …

Abstract The EU Regulation No 517/2014 is going to phase-out most of the refrigerants
commonly used in refrigeration and air conditioning systems (R134a, R404A and R410A) …

Usage of eco-friendly refrigerants could be an effective solution to the global warming
problem. However, a comprehensive assessment is necessary when selecting new …

HFC refrigerants as R134a, R404A, R407C and R410A are commonly used in heating, air
conditioning and refrigeration (HACR) systems since Kyoto protocol. However, they are …

In this paper, the environment friendly refrigerant options suitable for automobile air
conditioners are reviewed. Initially, the thermophysical, thermodynamic and chemical …

R1234yf, a substitute for R134a, shares similar thermodynamic behavior and eco-friendly
properties with low global warming potential. However, performance and flammability issues …

With its ability to accomplish heat transfer, the ground heat exchanger (GHE) is a crucial
component of a ground source heat pump system. Numerous research on various kinds of …

As a low GWP alternative refrigerant to R134a, the direct use of R1234ze (E) in water source
heat pumps leads to significant performance degradation. Vapor injection combined with …
