Solstice family of HF Solstice family of HFOs

Low Global Warming Molecules

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 of 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.

HFO Success Story

Vending Machine

HFO1234yf performance is similar to R134a.

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..

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)

Compressor Development
