TO MEET LGWP REQUIREMENTS
Petra Engineering completed a new project
in
gi
Development Organization (UNIDO) that aims to replace
refrigerants that contribute to Ozone Depletion and have
a high Global Warming Potential (GWP) factor.
The initiative implements use of Low GWP propane (R290)
as a refrigerant in the manufacturing of large commercial
The initiative implements use of Low GWP propane (R290)
as a refrigerant in the manufacturing of large commercial
unitary roof-top HVAC units of up 113 Tons (400 kW).
The project is " considered as a unique cooperation
testing initiative with the UNIDO to manufacture large
The project
is " considered as a unique cooperation
testing initiative with the UNIDO to manufacture large
HVAC equipment with a Low GWP factor " .
It was conducted in response to a decision by the UNIDO
executive committee to use natural
refrigerants and
adopt the Kigali Amendment to the Montreal Protocol.
Complying
with
the
fluorinated
greenhouse
gases
regulation (EC517/2014), commonly referred to as the
F-Gas Regulation, that introduced a phasedown of high
GWP gases by limiting the amount of gas that can be
placed on the market and considering the A2L Low GWP
refrigerants as a new safety classification from ASHRAE
denoting lower flammability, sometimes referred to as
" mildly flammable " , Petra is testing multiple Low GWP
gases such as R-32, R-1234ze, R-452B and R-454A, B, C &
D of the A2L family and a replacement for the common
nowadays used refrigerants of R-134a and R-410A.
Another characteristics Petra is considering is " Flammability "
of the new LGWP. A2L refrigerants have lower flammability
and slow flame propagation (burning velocity <10 cm/sec)
Petra's product offering using low GWP refrigerants
includes (but not limited to) Roof Top Units, Chillers,
Computer Room Air Conditioning (CRAC) units, Central
Split Systems and Residential Split Systems.
