“My top 3 priorities to bring natural refrigerants faster to<br />
market would be:<br />
1. Implement hybrid refrigeration systems (i.e.<br />
CO 2<br />
/R134a) before setting up 100% natural refrigeration,<br />
especially in countries where ammonia and/or CO 2<br />
transcritical design is not yet mature.<br />
2. Convince refrigeration manufacturers/installers that<br />
standardization and built-in rack compressors must<br />
help to reduce the price difference between conventional<br />
and natural refrigeration systems.<br />
3. Promote to installers that the future of refrigeration is<br />
to switch their activity to natural refrigeration through<br />
training, certification, etc.”<br />
Jean-Michel Fleury, Carrefour<br />
“1. Encourage end users to “Go for it”! The technology is<br />
here – and it works! To us (Coop Norway), it seems there<br />
is enough experience and studies that prove natural refrigerants’<br />
success, environmentally and economically.<br />
2. Although hardly the fastest approach; political action<br />
in order to increase (and harmonise) taxes on synthetic<br />
refrigerants.<br />
3. “Ally” with producers, in order to continue developing<br />
the technology.”<br />
Knut Lutnæs, Coop Norway<br />
“1. There is one main reason which speaks against CO 2<br />
systems and this must be fixed: Price reduction of CO 2<br />
systems to the level of conventional cooling systems;<br />
2. Development of low-cost compact systems for small<br />
convenience stores”<br />
Elias Steiner, SPAR Switzerland<br />
“To incentivise investment in natural refrigerants we need:<br />
1. Education for designers<br />
2. Test natural refrigerant installations in all countries<br />
and educate maintenance technicians about the technology.<br />
3. Further educate end-users and contractors about the<br />
natural refrigerant installation options.”<br />
Ilpo Hakkarainen, Kesko Finland<br />
“To begin with we need to address education of the professionals<br />
in the refrigeration industry, which means the<br />
planners, the installers and also the technicians operating<br />
and maintaining the systems. Secondly, the manufacturers<br />
need to undertake more R&D on components such as<br />
compressors and regulation valves. Thirdly I think we need<br />
certain guidelines from the legislative point of view, such as<br />
a tax on HFCs or guidelines recommending the use of CO 2<br />
in certain applications.”<br />
“Delhaize Belgium is one of the frontrunners bringing natural<br />
refrigerants to its supermarkets by using CO 2<br />
exclusively<br />
for negative installations. Its top 3 priorities to bring natural<br />
refrigerants faster to market would be:<br />
1. To have encouraging incentives from authorities promoting<br />
faster retrofit/renewal of existing installations<br />
2. Transform old installations R22 (two stage compressors)<br />
directly to CO 2<br />
3. Bring together constructors/producers/users to find<br />
new uses with natural refrigerants like propane,…<br />
Delhaize has chosen to invest in natural refrigerants because...<br />
1. It is more environmental friendly<br />
2. It is more efficient on the energy side<br />
3. In case of leaks, there is no impact on greenhouse gas<br />
(GHG) emissions<br />
4. Technology, like sub-critical installation, is reliable<br />
5. Prices of installation are becoming more and more<br />
competitive”<br />
