We in the UK as an industry take manufacturers statements as balanced, responsible, supported and apply not only to the UK, Europe but the whole world. We trust! there is no political/commercial agenda that tells the AC owner that his equipment life span is x years. Look at the car industry with leaded petrol.
There is a good reason why 140 countries including UK & EUROPE etc aligning themselves to the Kigali Amendment. There ia good reason why the French, Italian & Spanish building Regs ensure that it is almost impossible to use Flammables!.
The F-Gas regulation DOES not promote Flammable refrigerants! it simply encourages the reduction of Hi GWP.
The upcoming ban for AC is 2025, not 2020 and only for split systems with less than 3kg charge. It has excellent exemptions +4 years, relating to safety and a better life cycle emission.
We should read it correctly!
Safety has a higher priority than environmental /commercial gains. The Environment gets affected if refrigerant accidentally leaked with R410A but at least it is not going to possibly burn the building!!
We must act responsibly. Neil Afram is not anti flammable but anti risks that affect safety.
Comment on: AREA unveils EN378 refrigeration guidance
Excellent document and well presented with illustrations. It can be easily followed by the majority of system contractors and specifiers.
Question is how to get it to a one-man-band system installer who is installing a 1-6 kW a day to help him follow the recommendations? how to control it? there are millions of small splits from being a danger to the installer or the end-user? especially when flammable is forced down their throat ;) Do we think that manufacturers ought to included as part of the installation manual? recommend it as part of their training?
One thing I didn't see in the document is loud danger labeling of equipment? perhaps the HSE or advertising standards can help? we all have to chip in to make it work and safe!!!. Neil Afram
Good news and trust there are more manufacturers opt for this safe alternative. As Global Fact states " There is more to consider than GWP" here I am talking about SAFETY in the AC split market where there are more than 65m sold worldwide, managed and installed by very small (one-man band, probably 80% of sales), yes qualified engineers, installed anywhere, any application, most refrigerant release is at installation (be it grames) but flammable ?. to expect engineers to take the blame when there is no choice (yes no choice! as some manufacturers decided in Europe and especially in the UK decided to stop R410A some 5 years ahead of F-Gas bans) ? no guidelines or safety regulations ?
This request is on the assumption that whatever refrigerant to replacing the Hi GWP needs to be in line with HSE guidelines as I believe there is considerable confusion regarding replacement with LGWP. There are two types of LGWP refrigerants, Flammable (or mild ...) which there is no government or HSE guidelines (as in France for example) and NON-Flammable which already has guidelines and has over 20 years experience and over 45000 engineers certified. Need also to be clear regarding the incorrect claims regarding Flammable LGWP as being environmentally friendly! This is true IF it LEAKS, but nobody talks about if flammable leaks and causes fire it can kill and the fire causes more environmental damage than non-flammable?. We need to force the government to create more understanding, clarity and safe products than just listening to manufacturers of both Chemical and equipment. The F-Gas regulation is quite clear on the timing and exemptions.https://www.spaceair.co.uk/uploads/files/VRF/R32/Extract%20Ban%20on%20F-gas%20gov_uk.pdf
The AC & Refrigeration industry are users of refrigerants not consumers i.e. we don't take leaks likely!
Hi I assume this refers to 404A used in Refrigeration Extract from F-Gas bans:
HFCs with global warming potentials of more than 2,500 will be banned in all refrigeration systems. This will mainly affect the use of HFC 404A in commercial and industrial refrigeration systems.
