*******www2.dupont****/ISCEON/en_US/index.html?src=metacafe_dupont_refrig_08 There is a continued drive to reduce the environmental footprint of refrigeration systems and increase the energy efficiency of air conditioning systems. Barbara Minor, a DuPont Engineering Fellow, and Nick Strickland, a DuPont Market Development Manager, discuss market drivers for developing R-22 replacements and the broad range of refrigerant solutions that have been developed by DuPont for new and existing equipment. Barbara Minor, Engineering Fellow DuPont Refrigerants: Well, DuPont has a product line for new equipment as well. And, ..., you can always go to DuPont’s Refrigerants Web site. There’s information on all of our products there. But there … there are refrigerants for new equipment. For example, 410A is a preferred refrigerant for new air conditioning systems. But, its properties are very different from R-22, so it would not be an option to retrofit a current system. And so, most of the air conditioning companies, in the new equipment they’re designing, are choosing products like 410A, because of high energy efficiency and high capacity. And then, supermarkets, there are products there as well. So there are options, whether you want new equipment, or whether you wanna try and keep your R-22 equipment running. ..., there’s a solution. Nick Strickland, Market Development Manager DuPont Refrigerants: We look to the future, it’s, I think what might happen is a continued divergence of technologies and continued divergence of different categories of refrigerants. ... … mostly, there’s going to be a pretty strong trend toward lower global warming potential products that Barbara is working on now. ..., but, when you look at CO2 emerging in the supermarkets, or you look at the … ..., geothermal, or the loop cooling in… in residential markets, you can see there’s a trend toward zero ozone depleting, lower refrigerant charge size, ..., lower overall global warming potential. And … and … Barbara Minor: And … and I think that could sort of be encompassed overall, in just … reduce the environmental footprint, of, ... … of everything. From … Nick Strickland: Right. Barbara Minor: LEEDs in buildings, ..., to … to zero-based energy buildings. ..., a … the air conditioning systems, the refrigeration systems are an integral part of that. So there’s a contin … continued drive to increase the energy efficiency … of anything that uses energy, and so that’ll be a key element of refrigerant development going forward …trying to find the highest energy efficiency refrigerants we can, that have the least environmental impact from a climate change perspective. ... … so, I think … I think the drivers are … are really clear. We see that through climate change. We see that through the concern about energy, ..., on a global basis. And so, it makes our technology development direction pretty clear, also.
