1.11.1 Product features
Refrigerant which is used in the air conditioning systems for ve‐
hicles, belongs to the new generation of refrigerants which is
based on chlorine-free hydrofluorocarbon (HFC, R134a).
In regards to their physical behavior, this relates to under pres‐
sure liquefied refrigerant. They are subject to the pressure tank
regulation and must only be filled into approved and marked pres‐
sure gas tanks.
For safe and proper use, certain conditions which apply must be
respected.
1.11.2 Using refrigerant R 134a
WARNING
There is a risk through icing.
The refrigerant can leak as fluid or as vapour.
Do not open the reservoir in which the refrigerant is.
If the refrigerant reservoirs are opened, the contents can leak as
fluid or as vapour. This procedure is more intense the higher the
pressure is inside the reservoir.
How high the pressure is depends on two conditions:
• What type of refrigerant is filled in the reservoir. The rule is:
The lower the boiling point, the higher the pressure.
• How high the temperature is. The rule is: The higher the tem‐
perature, the higher the pressure.
1.11.3 Wear safety goggles
Wear safety goggles. It prevents that refrigerant gets into the eyes
and possibly severe damage caused by frostbite.
1.11.4 Wear protective gloves and apron
Refrigerants dissolve fats and oils pretty well. When in contact
with the skin, therefore remove the protective fat film. However,
degreased skin is sensitive to cold and disease germs.
Do not spill liquid refrigerant onto the skin. The heat to vapourise
extracts the refrigerant from the surrounding area. Thus, very low
temperatures can be achieved. This results in local frostbites
(boiling point of R134a ambient pressure at -26.5°C).
