Hydrofluoroolefins

Ammonia is “a superior refrigerant” to HFOs and low-charge ammonia systems are improving safety and reducing regulatory burdens, Gerard von Dohlen, president of Newark Refrigerated Warehouse, said.

The Kigali Amendment to the Montreal Protocol, which will phase down HFC consumption in developed countries by 85% by 2036 (compared to a 2011-2013 baseline period), will enter into force on 1 January 2019.

Johnson Controls’ new York YZ centrifugal chiller is said to be the first such machine designed specifically for use with low GWP refrigerant R1233zd and using magnetic bearing technology.

With the phase-out of HCFCs (hydrochlorofluorocarbons) under the Montreal Protocol on Substances that Deplete the Ozone Layer progressing, the introduction of alternatives with not only zero ozone depleting potential (ODP) but also low global warming potential (GWP) and improved energy efficiency is becoming an issue of increasing importance, especially in developing countries.

Tests carried out by a major supermarket have shown that refrigerated display cases are at their most efficient when specifically designed for use with doors.

The implications of the European F-gas regulations and phase down will be discussed in a new forum set up for public sector employees in London and the South East.

Trane has expanded its Sintesis range of air-cooled screw chillers using low GWP refrigerant R1234ze.

A municipal kitchen in Saint-Brieuc, Brittany, has been upgraded with a refrigeration system using a combination of the HFO R1234ze and R455A, a lower GWP alternative to R404A.

Shipping company Hapag-Lloyd has invested in 1,000 Star Cool Integrated containers using refrigerant R513A, the lower GWP alternative to R134a.

Danfoss has expanded its Turbocor TT Series compressors to use the lower GWP refrigerant R513A and added new low lift capabilities.

Aermec is introducing its new range of air-cooled and water-cooled R1234ze chillers at this week’s Interclima exhibition in Paris.

A new document from Beijer Ref seeks to clarify what refrigeration equipment is currently approved as suitable for use with the new generation of lower GWP refrigerants.

The European Commission has ended its antitrust investigation into cooperation between Honeywell and DuPont (now Chemours) on the production of refrigerant R1234yf.

AGC Asahi Glass (AGC), a world-leading manufacturer of glass, chemicals and high-tech materials, announces that it has obtained certification for AMOLEA 1224yd, a new refrigerant with a lower environmental impact. The certification was granted in October 2017 by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE), marking the first time for a Japanese company to obtain approval for a new chemical substance. AGC intends to begin commercial production of AMOLEA 1224yd in early 2018, and will continue to increase capacity in line with demand growth.

There is still time to submit your abstract for the inaugural IIR International Conference on the Application of HFO Refrigerants with an extended deadline to 30 October 2017.

The global refrigerants market is estimated at USD 14.49 Billion in 2017 and is projected to reach USD 18.05 Billion by 2022, at a CAGR of 4.5% from 2017 to 2022. In this report, 2016 is considered the base year and the forecast period is from 2017 to 2022.
