The Oak Ridge National Laboratory (ORNL) High-Ambient-Temperature Evaluation Program for Low-Global Warming Potential (Low-GWP) Refrigerants aims to develop an understanding of the performance of low-GWP alternative refrigerants relative to hydrochlorofluorocarbon (HCFC) and hydrofluorocarbon (HFC) refrigerants in packaged or Rooftop Unit (RTU) air conditioners under high-ambient-temperature conditions. This final report describes the parties involved, the alternative refrigerants selection process, the test procedures, and the final results.

Adcock Refrigeration and Air Conditioning has completed a major R22 replacement project at leading IT systems, services and products company Fujitsu Services.

The Oak Ridge National Laboratory High-Ambient-Temperature Evaluation Program for Low Global Warming Potential (Low-GWP) Refrigerants project was aimed to develop an understanding of the performance of low-GWP alternative refrigerants to hydrochlorofluorocarbon (HCFC) and hydrofluorocarbon (HFC) refrigerants in mini-split air conditioners under high-ambient-temperature conditions. This final report describes the parties involved, the alternative refrigerant selection process, the test procedures, and the final results.

The R134a market in Europe is set to undergo an inevitable decline from 1st January 2017 following regulatory changes affecting fluorinated gases for automotive air conditioning taking effect on that date. In this sharply declining market, Arkema has decided to put forward to the Central Works Council today a project for the closure of the R134a fluorogas plant at its Pierre-Bénite site (France). This proposed closure would not result in any redundancies.
