as a CFC-114 replacement refrigerant in high temperature heat pumping applications. Title, date, research focused on safe groupon recuperation point use of combustible refrigerants Jul 11, 2018, highlights from the conference on cold chain and refrigeration exhibition in China Apr 30, 2018. Apr 16, 2014 Quantifying global warming potential Apr 23, 2014 New F-gas Directive, one step closer to the final decision! It is estimated, that indirect emissions in some cases can represent more than 84 of total GHG emissions, thus improving efficiency is vital to mitigate system impact on climate change. Creating an energy and environmentally efficient refrigerating system is a very complex process. The low GWP potential of HFOs is utilized in the refrigerant blends, while also mitigating their flammability.
The experimental measurements showed 4-8 decrease of COP, when HFC-1234yf is used as a drop-in replacement with no system modifications. Recent legislative measures have led to development of new low global warming potential (GWP) refrigerants with comparable performance to those refrigerants which they replace. Thus, for the same temperature difference theoretical COP could vary greatly: compare.56 (CO2) and.60 (R134a) for a fixed condenser (30 oC) and evaporator (-15 oC) temperatures. It is estimated that they are responsible for approximately 10 of total worldwide CO2 equivalent emissions released. Published, may 08, 2012, the air-condition and refrigeration systems are significant contributors of greenhouse gases (GHG) in atmosphere.

However, this comparison is not fare enough as it is extremely difficult to establish correct efficiency comparison of different refrigerants in the system as due to varying properties the components adjustment is usually required. Nowadays, HFOs are seen to become new widely used low GWP refrigerants.
However, with some simple modifications (e.g. Are we on track to meet it? If tested in similar conditions, the HFO-1234yf performance showed to be lower than that of HFC-134a currently used in similar MAC systems.
