NEW REFRIGERANT R452A AS R404A REPLACEMENT: A LOWER GWP OPTION FOR TRANSPORT REFRIGERATION

NEW REFRIGERANT R452A AS R404A REPLACEMENT: A LOWER GWP OPTION FOR TRANSPORT REFRIGERATION

01.03.2015

In order to lower the Climate Impact of transport refrigeration equipment, a major manufacturer has launched a new line of trailer and self-powered truck units using R452A refrigerant (GWP of 2,140), anticipating the 2014 F-Gas Regulation which will soon ban high GWP R404A (GWP of 3,922).

Refrigerated transport requires safe, non-flammable and low toxicity refrigerants, able to work efficiently under a wide range of ambient conditions.

Despite its not-so-low GWP, R452A is considered to offer the right choice for this application among available drop in refrigerants. A blend of HFC-32/HFC-125/HFO-1234yf (11/59/30 weight %), it is non-flammable, closely matches R404A properties and performance, and offers a low compressor discharge temperature.
