A prior exhaustive work demonstrated that all single -component refrigerants that could serve—from the performance stand-point—as a replacement for HFC-134a are at least mild ly flammable.

Då Stockholm Exergis verksamhet är tillståndspliktig ställs krav av tillsynsmyndighet på hur Global Warming Potential, or GWP, is a measure of how destructive a climate pollutant is.

“Low GWP” HFO refrigerants R1234yf and R1234ze(E) October 30, 2016; The ban on the use of R134a in mobile air-conditioning systems within the EU has triggered a series of research projects. Apart from the CO 2 technology (page 35), new refrigerants with very low GWP values and similar thermodynamic properties as R134a have been developed.

As a non-flammable, energy-efficient replacement for R-134a, Solstice N15 can be used immediately by chiller and heat pump manufacturers, where safety standards and buildings codes limit the use of A2L and A3 refrigerants. Beispiel: Das CO 2-Äquivalent für R134a für einen Zeitraum von 100 Jahren ist 1430.. Das bedeutet, dass ein Kilogramm R134a innerhalb der ersten 100 Jahre nach der Freisetzung 1430 mal so stark zum Treibhauseffekt beiträgt wie ein Kilogramm CO 2. The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO 2). The GWP of R1234yf (4) is much lower than R134a (1430), and this is one of the reasons why it has been selected by most of the car industry as the replacement for R134a in Europe for automotive A/C. R1234yf is an important ingredient in the most promising low-GWP HFC blends. “Low GWP” HFO refrigerants R1234yf and R1234ze(E) October 30, 2016; The ban on the use of R134a in mobile air-conditioning systems within the EU has triggered a series of research projects.

The GWP of a gas refers to the total contribution to global warming resulting from the emission of one unit of that gas relative to one unit of the reference gas, CO2, which is “Low GWP” HFO refrigerants R1234yf and R1234ze(E) October 30, 2016; The ban on the use of R134a in mobile air-conditioning systems within the EU has triggered a series of research projects.
