Hydrofluoroolefins

Climaveneta heat pump chillers using low GWP, HFO refrigerant R1234ze are to reclaim waste heat from a data centre for one of Finland’s largest district heating networks.

R514A, the low GWP refrigerant replacement for R123, has been added to Bacharach’s library of detectable gases.

Against a background of a global HFC phase down, this year’s European Conference on the latest refrigeration and air conditioning technologies takes on greater significance.

Danfoss has added four new Turbocor compressors for use with the HFO refrigerant R1234ze, and updated its existing TG310 model.

ASHRAE in partnership with other international organizations has announced that registration is open for the conference on Sustainable Management of Refrigeration Technologies in Marine and Off-Shore Fisheries Sectors, April 6-8, 2017 in Bangkok, Thailand.

More must be done to lift barriers to natural refrigerant uptake such as restrictive safety standards, the EIA’s Clare Perry told visitors to the EuroShop tradeshow yesterday.

Since February 27 till March 2, 2017, a meeting of representatives of refrigeration associations of Armenia, Kazakhstan, Kyrgyzstan, Moldova, Tajikistan, and Ukraine as well as working groups from Azerbaijan and Turkmenistan took place in Moscow. It resulted in establishing the Interstate technical committee which will help specialists in refrigeration solve their common problems.

Compressor manufacturer SECOP argues that its improved range of compressors utilising variable speed technology can reduce energy costs in light commercial and household applications.

Agreed upon in October 2016 after negotiations from over 170 nations, the Kigali Amendment to the Montreal Protocol seeks to phase out the use of hydrofluorocarbon (HFC) refrigerants due to their high global-warming potential (GWP), paving the way for newer, low-GWP refrigerant materials to enter the marketplace. Although the Kigali Amendment is certainly the most prominent refrigerant-related ruling in recent years, several other regulations focused on reducing the use of high-GWP chemical refrigerants have been implemented, including major delistings of HFCs in Europe, the U.S. and Japan. This article provides perspective on low-GWP refrigerants and some attendant operational considerations, and also highlights two refrigerant-free cooling technologies.

The study finds that the market has slowly recovered from past years of lackluster performance. In 2016, the China market for blowing agent is valued at RMB 6.3 Bn and around 400,000 tons of blowing agents are sold. The domestic market is expected to maintain stable growth rates through to 2021. Because of the Montreal Protocol, China will be reducing its HCFC production and consumption to 35% of baseline level in 2020. This will mean that many downstream users in the building materials market especially those making PU and XPS foams will have to switch to other blowing agents by then. This change is by no means a small one, as HCFC is still the second largest segment in 2016. With the phase out of HCFC, there will be more users switching to hydrocarbon (HC), HFC and HFO blowing agents. Through a comprehensive study of the market, this report will identify the possible opportunities available for existing and potential players looking to capitalize on this development.

Kirloskar, the Pune-based chiller manufacturer, is the first company in India to announce the use of low GWP refrigerant R1234ze(E).

A Midwestern retail chain has chosen the lower GWP refrigerant R448A over CO₂ for a new store in Isanti, Minnesota.

Mitsubishi Heavy Industries has extended its range of chillers running on new low GWP refrigerant R1234ze(E) to cover capacities from 150 to 5,000TR.

A search of more than 60 million chemicals to find a replacement for R410A in air conditioning systems has found just 27 suitably-efficient fluids – but all are at least slightly flammable.

140 papers were presented during the successful 12th IIR Gustav Lorentzen conference on Natural refrigerants. CO₂ was the most addressed refrigerant (74 papers), followed by hydrocarbons (34), ammonia (21) and water (4). We present below the summary of a paper along with the direct link where the paper can be downloaded in Fridoc database.
