R454C R454B R513A R449A Fourth generation environmentally friendly refrigerant

Since 2015, the European Union's Fluorinated Gas Regulation (F-Gas) has been promoting retailers to replace hydrofluorocarbon (HFC) refrigerants with new refrigerants with lower global warming potential (GWP) to achieve long-term sustainability. Does this mean that when choosing a new refrigeration solution, people only need to pay attention to the GWP of the refrigerant?

In fact, the indirect emissions generated by electricity consumption in refrigeration systems have a much greater impact on climate change than the GWP of refrigerants themselves. At the same time, the energy consumption of the refrigeration and air conditioning industry is high. If the energy efficiency decreases after replacing old and new refrigeration systems, it will not be conducive to achieving low-carbon sustainable development. This means that when choosing a new refrigeration solution, not only should the GWP of the new refrigerant itself be considered, but also its operational efficiency in the system should be taken into account.

Therefore, when selecting new generation refrigeration technologies based on their impact on climate change, the total emissions, including direct emissions (GWP) and indirect emissions (energy efficiency), are the primary considerations.

The following are the current alternative solutions for traditional refrigerants by the American company Komus:
