R-1234ze

he 1234ze is a zero ozone depleting refrigerant with very low global warming potential (GWP), developed to comply with the European F-Gas Directive, for the phase-out of refrigerants with high global warming potential in various applications. With an atmospheric heating potential of 6, the 1234ze is an energy efficient alternative for a wide variety of medium temperature applications.

1234ze is slightly flammable (A2L), and requires minor changes in equipment design to be used in new equipment.

Applications:

– Supermarkets.

– Commercial buildings.

– Heat pumps.

– Refrigerators.

– Vending machines.

– Beverage dispensers.

– Air dryers.

– CO2 cascade systems in commercial refrigeration.

– Foaming agent.

PERFORMANCE:

Field tests on air-cooled chillers have shown a significant reduction in energy consumption compared to propane (R-290). In addition, compared to traditional refrigerants, the properties and performance characteristics of 1234ze are similar, but without the environmental penalty of high-GWP HFCs.

If equipment modifications are made to compensate for the loss in cooling capacity compared to HFC-134a, 1234ze will provide a higher energy efficiency or coefficient of performance (COP) than R.134a in a wide range of applications and conditions. According to compressor experts, HFO performance can be further improved by optimizing compressor design. Reciprocating, Sroll, screw and centrifugal compressors can be used.

– No harm to the ozone layer, ODP = 0.

– Working pressures similar to those of R-134a.

– Slightly lower cooling capacity than R-134a.

– Energy efficiency superior or equivalent to R-134a.

– Global Warming Potential (GWP) = 6

– Boiling point at 1.013 bar (ºC): -19.00

– UN NO.: 3163

– Safety classification: A2L. Low toxicity and slightly flammable.
