An Introduction to A2L Refrigerants - Refcom
www.refcom.org.ukThe 2015 F-gas regulation is driving industry to use lower GWP1 refrigerants in many applications. The EU regulation (517/2014), stwhich came into force on the 1 January 2015, introduces a ban on new equipment using HFC refrigerants with a GWP of over 2500 by 2020. The regulation also introduces a phase down, related to GWP and measured in CO 2

It exhibits higher pressures and refrigeration capacity than R-22. The compositions of Freon™ 407C and Freon™ 410A are as follows: HFC-32 HFC-125 HFC-134a
General Product Catalogue 2022 - Emerson
climate.emerson.comCompared to previous systems with A1 refrigerants, systems with A2L refrigerants require additional system safety measures because of their slight flammability. Emerson marks all compressors/units that are qualified for A2L refrigerants with a sticker indicating the usage of flammable refrigerants.

www.irbnet.deMany alterative refrigerants were invented to be used instead of these harmful refrigerants and the researches for developing new are still taking place. The refrigerants that are used as replacement for the HFC’s are R134a, R404A, R407A, R410A, R22, and hydrocarbons (propane and butane) and ammonia.
R32 Common Questions - AIRAH
www.airah.org.aurefrigerants. There is a diversity of low GWP refrigerants available to select from. These include HFC 32 (or R32), HFO 1234yf and HFO blends, Ammonia (R717), Propane (R290) and C02 (R744). Unfortunately, none of these candidates is a perfect refrigerant when assessed across the 4 key criteria of Environment, Energy Efficiency, Safety and Economy.
