New Hydro-Fluoro-Olefins have been developed:

• HFO-1234yf has been identified as replacement for R134a by

the automotive industry.

• It has an atmospheric life of only 11 days (12 years for HFC-134a)

and an extremely low GWP of only 4 (1430 for R-134a).

• ASHRAE std 34 has classified HFO-1234yf as low toxicity class A.
• HFO-1234ze, is currently replacing R-134a for one-component

foam applications and looks promising for centrifugal chillers.

• This molecule also has a very short atmospheric lifetime with a GWP
• f 6.
• ASHRAE std 34 has classified HFO-1234ze as low toxicity class A.
• Another molecule is currently under development and is code

named N12.

• Intended refrigerant application is low pressure centrifugal chillers.

High temperature Heat Pumps and ORC.

• It has a GWP of 7 and is non-flammable.

Air dryer applications

Production Ready HFO1234yf and HFO1234ze Air Dryers

 Frascold validation of its reciprocating compressor with Solstice L13.  Better COP versus R134a across a wide range of operation.  Frascold announced investing in next generation HFO optimised compressors..

Compressor Development

HFO 1234ze Water Chiller

First HFO Chiller operational at Waitrose supermarket (South London).

 Important reduction in energy consumption versus identical R290 chiller reported.. Frascold /Geoclima tests show a 3.5% higher COP versus R134a Chiller.

HFO-1234ze in Commercial Refrigeration

• Limited prototype availability to OEMs in April 2012 for

development testing

• Significant energy efficiency increase over equivalent

HCFC 134a compressors

• Designed with environmentally friendly, ultra-low GWP

refrigerant HFO-1234ze

• Optimal solution for outdoor applications (air-cooled)
