Climate change has rightly led to growing interest in the environment and, in our application area in particular, in the impact of the type of refrigerant gas used in all climatic appliances such as the ones we manufacture.
We are referring to consequences both from the ethical point of view, from the discussion on the topic, and officially from the legislative point of view.
The European Union has already moved in this direction with Law No. 517 of 2014, which progressively implies the reduction of HFC refrigerants in the years following the one of the standard.
However, in the legislation, 2019 is the year in which the reduction of HFC refrigerants (hydrofluorocarbons) must be decidedly more consistent.
The various limitations have led to the emergence of new solutions with low GWP (Global Warming Potential).
The last generation of fluids now on the market, the fourth, called HFO (Hidro Fluoro Oleofine) must guarantee a much lower greenhouse effect than the previous one, which presented a high GWP content.
The new gases have the ideal goal of being non-toxic, non-flammable, with a very low environmental impact, and an equally low cost of installation and maintenance.
The synthetic HFO molecules currently available on the market are R1234yf, R1234ze, R1234zd.
Compared to the ideal goals to be achieved, each of them has excellent values for one parameter and maybe worse values, compared to another molecule, for other parameters.
For example, the r1234zd is not flammable, but it is not the one of the three with the lower GWP content. The other two still have a minimal risk of flammability.
In short, the perfect refrigerant does not yet exist, but those mentioned above are the gases currently used in refrigeration.
In FDM we are always up to date with new regulations and manufacture equipment in line with the updated European directives.
The new gases we have been using from January 1st, 2019 comply with the current European directives and guarantee the use of your equipment even beyond 2030.
