(1) Mixture consisting of 52 % HFC-143a, 44 % HFC-125 and 4 % HFC-134a.
The GWP value is determined from this.
(2) Mixture consisting of 53 % HCFC-22, 13 % HFC-152a and 34 % HCFC-124.
The GWP value is determined from this.
(3) Mixture consisting of 38 % HCFC-22, 60 % HFC-125 and 2 % propane.
The GWP value is determined from this.
(4) Mixture consisting of 25 % HFC-125, 52 % HFC-134a, and 23 % HFC-32.
The GWP value is determined from this.
(5) Mixture consisting of 46 % HFC-143a and 7 % HFC-125.
The GWP value is determined from this.
(6) A HCFC mixture consisting entirely of HCFCs, where the GWP - in accordance with the climate convention guidelines - is 0, since the mixture does not contain greenhouse gases. The real GWP value is 1,440.
(7) Mixture consisting of 50 % HFC-32 and 50 % HFC-125
(8) Mixture consisting of 50 % HFC-125, 50 % HFC-143a.
The GWP value is determined from this.
