For the latest data available in the latest EEA report, in 2019 HFC-32, HFOs and HCFOs accounted for about 43% of the reported total supply of HFCs/HFOs/HCFOs as metric tonnes, this is an increased share compared with 2018 (37%). The average GWP for reported total supply has decreased by 40% in just 5 years from […]

The data centre modernisation installed chillers compatible with the low GWP refrigerants mildly […]

New heat pumps have become available on the market that use low GWP R-32 or R-454B and offer improved heating and cooling efficiency for a wide range of commercial applications, such as office buildings and hotels. One new series of R-32 units are factory-filled supporting installation by engineers for sanitary, heating and air conditioning technology […]

The International Energy Agency (IEA), has issued several analyses is part of a series from its new report, Technology and innovation pathways for zero-carbon-ready buildings by 2030. Heat pumps, district energy networks and renovation of existing building stock are crucial components to achieve this objective. High-efficiency electric heat pumps are the primary technology driving reduced […]

Most HFOs and HCFOs decompose in the atmosphere via an intermediate product which then breaks down further. The breakdown of the intermediate product CF3CHO (trifluoroacetaldehyde) has been investigated as early as the 1990s. In 2021 EFCTC published an analysis of the atmospheric degradation of this intermediate, which can occur via three routes. In that same […]

Summary Most HFOs and HCFOs decompose in the atmosphere via an intermediate product that then breaks down further to give hydrogen fluoride (HF) and carbon dioxide (CO2). The breakdown of the intermediate product (CF3CHO trifluoroacetaldehyde) has been investigated as early as the 1990s. It had been proposed in 2021 that the intermediate CF3CHO breaks down […]

An expansion project at a new beer bottling plant in the UK selected 1.2 MW HFO-1234ze(E) chiller instead of an ammonia system for process cooling and provides improved performance by up to 25% according to the energy efficiency ratio (EER) analysis. Ultra-low GWP HFO-1234ze(E) is mildly flammable and non-corrosive in comparison to ammonia, which is […]

In response to the public consultation on the F-gas Regulation, EFCTC commented that the structure of the F-Gas Regulation works in its current format as it provides the market flexibility to make appropriate refrigerant choices while fostering the use of lower GWP refrigerants in combination with measures directly targeting the reduction of refrigerant related emissions. […]

EFCTC News Tim Vink, our EFCTC vice-chairman, will be taking a well-earned retirement from Honeywell at the end of 2020. Tim has been EFCTC vice-chairman for nearly 20 years, has taken the lead on countless issues, drafted numerous position papers and letters plus represented EFCTC at many meetings. He has always brought his analytical mind […]

The HFOs and HCFOs are becoming the refrigerants of choice for large chillers due to their ultra-low GWPs, energy efficiency, and low or non-flammability. HCFO-1233zd(E) centrifugal chillers from 3 different manufacturers have received environment awards around the world for their class leading performance using this non-flammable refrigerant with GWP of 1. Its boiling point of […]

Increased adoption of heat pumps will help to decarbonise heating. The majority of heat pumps use fluorinated hydrocarbons with R-410A being most widely used currently, but lower GWP HFC-32, HFO/HFC blends and HFOs all have an important role to play in the wider adoption of heat pumps. This item reports on R-32, R-454C and R-1234ze(E) […]

A German supermarket has just been renovated and made the choice of an R-455A ice-water loop for its medium temperature refrigeration system. Previously tried CO2 systems had encountered pressure surges problems which caused damages and were more expensive then R-455A (GWP of 150 and mildly flammable A2L classification). Seven display cases are cooled independently by […]

Hybrid Variable Refrigerant Flow (HVRF) air conditioners are a recent new development in the field of building air conditioning, reducing by 40 % the quantity of R-410A in the system and delivering a COP (Coefficient of Performance) over 6. The new system works without using refrigerant in occupied spaces and reducing the refrigerant quantity is […]

The Helsinki HFC-134a based District Heating and Cooling system has been expanded to become fully integrated by the addition of two new heat pumps delivering together 15 MW of cooling and 22 MW of heating. After expansion the heating (90MW) and cooling (60MW) plant will deliver an overall energy saving of 80%. The fully integrated […]

A British supermarket chain has retrofitted one of its supermarket refrigeration system with R-449A (GWP = 1 397), a blend containing R-32/R-125 /R-134a/R-1234yf / (24.3/24.7/25.7/25.3 weight %) as a replacement for R-404A (GWP =3 922). The system comprises two high temperature packs and one low temperature pack.

For the renovation of the the oldest Strasbourg (France) swimming pool heating system, an old gas boiler has been replaced by 2 HFC-134a geothermal heat pumps, delivering each 558 kW heating and 482 kW cooling. Within one year functioning, the energy consumption for the swimming pool and its adjacent buildings has been divided by five. […]

HFO-1233zd(E) has been chosen for the replacement of the outdated Eurotunnel HCFC-22 refrigeration system.

A new type of HFC-134a based hybrid chiller heat pump has been selected to provide simultaneously heating and cooling for the Kingston College’s new Creative Industries Centre in London.
 

A French application, designed to help F-Gas users to implement the F-Gas Regulation 517/2014, won the 2015 Cooling Industry Award “Refrigeration Product of the Year – Component or accessories”.

The Alpe d’Huez ice rink has recently been completely renovated, and the former HCFC-22 refrigeration system replaced by a cascade system HFC-134a/CO2.

In anticipation of the F-Gas Regulation 517 (2014) which will ban HFCs with a GWP higher than 2,500 by 2020 in stationary refrigeration equipment, new blends having a lower GWP alternative to R-404A (GWP of 3,922) continue to be introduced for specific applications.

Heat Pumps are favored for their ability to deliver heat from low temperature sources at more useful temperature levels, with the advantage of contributing significantly to reduce primary energy and CO2 emissions.

An HFO-1234ze high performance high capacity chiller has won the CIBSE Energy Saving of the Year 2015 Award, providing further recognition of the chiller significant energy saving and low climate impact.
