1.4 Information regarding the refrigerant R1234ze(E)
If the heat pump contains fluorinated greenhouse gas R1234ze(E) (F-gas regulation N°
517/2014) (Global Warming Potential GWP: 1, classified in safety group A2L), it should
be equipped with a ventilated enclosure system or be installed in a special machinery
room. The machinery room must conform to the requirements set in EN 378-3 (2016)
clause 5. For more information, contact Customer Service.
R1234ze(E) is classified group 2 “non-dangerous” according to the criteria of Pressure
Equipment Directive (PED) both 97/23/CE and 2014/68/CE.
R1234ze(E) is classified in safety group A2L (EN-378 (2016), ASHRAE
Standard-2010). It is in the lower segment of the mildly flammable refrigerants. A
unique characteristic of this refrigerant is the absence of flammable mixture with air
below 30 °C of ambient temperature. That’s why it is nonflammable for handling and
storage.
When utilized in a system, R1234ze(E) could become flammable with air in case of a
leakage. If a flame occurs with R1234ze(E), the effect of this flame would be extremely
mild, as its very low heat of combustion combined with an ultra-low burning velocity
wouldn’t be enough to propagate a fire.
When selecting the installation location for product using R1234ze(E), local building
codes and safety standards shall be followed and approval shall be obtained from
the local building authorities. In absence of local codes and standards, please refer to
EN-378 (2016) or to ISO-5149 (2014) as a guideline.
For further details on physical properties, flammability & toxicity characteristics,
hazards identification, installation safety requirements, etc., refer to standards such as:
● ASHRAE 34, EN 378, ISO-817 and ISO-5149
● Safety Data Sheet (SDS) supplied by the refrigerant manufacturer
● European Union’s REACH database (Registration, Evaluation, Authorization and
Restriction of Chemicals)
