Future for Natural Refrigerants
The use of hydrocarbons in domestic and light commercial ACR units could grow exponentially over the next few years, according some speakers at the second ATMOsphere America 2013 conference in Washington. This is assuming that some of the existing barriers such as public perception of hazards and the question of insurance could be resolved. The United States is already near to becoming a world lea...
R32 in Europe
In spite of industry doubts about the flammability of R32, Daikin is due to launch its R32-based range of packed air conditioner/heat pump units later this year. This refrigerant achieves a higher efficiency than R410A and also has a lower GWP of 675 compared with 2,088 for R410A. As a single fluid, it does not suffer from potential problems due to glide which could occur with multiple component f...
Reprieve for Radiators
Originally to be banned for use on heat pump systems under the EU energy labeling scheme, radiators have now spared from exclusion after protestations from the industry. The intention was to label any heat pump package as unsuitable for use with radiator systems. The industry has argued that improved emitter design in terms of water content and extended surface area means that a radiator can work ...
Added Benef it s from HFOs
A report in the quarterly journal Reviews of Geophysics (the United States) presents newly calculated data on a wide range of refrigerants and shows that the GWP of the current range of HFOs is lower than the baseline value of unity in terms of CO2. Up to now R1234yf has been listed as having a GWP of 4 and R1234ze as 6. On the relative merits of HFOs, Honeywell Fluorine Products points out...

Mercedes Allowed to Use R134a
Car and truck manufacturer Mercedes has been given approval by the French government to resume selling their vehicles in France with R134a-based air conditioners - effectively cancelling the previous ban which should have come into force from 2011. This avoids the requirement to adopt the still controversial refrigerant R1234yf. Current EU law allows the use of R134a until 2016. Source: ACR News, ...
World Production of Refrigerants
An analysis by the journal cci Zeitung (Germany) gives data on the maximum production capacity of the principal countries supplying refrigerants to the world market. China is listed as the international leader for R22 at 469,000 tons followed by the United States at 134,000 tons. This compares with a world market total of 860,000 tons. For R134a, China leads at 120,000 tons compared with the Unite...
