Commercial appliance manufacturers Hill Phoenix and Kysor/Warren, in addition to suppliers Honeywell and DuPont, are partners in the GreenChill Refrigeration Partners Help Cool the Planet campaign.
The campaign, in conjunction with the U.S. EPA, is promoting green refrigeration technologies, strategies, and practices that protect the stratospheric ozone layer, reduce greenhouse gases, and save money. Part of the campaign includes a "GreenChill" logo on refrigeration equipment in some supermarkets, including Whole Foods Market; Publix Super Markets Inc.; Giant Eagle; the Hannaford Bros. chain; the Harris stores; and Food Lion.
Honeywell supplied its Enovate blowing agent, a non-flammable, zero ozone-depleting hydrofluorocarbon liquid, to insulate the Hill Phoenix and Kysor/Warren refrigerator and freezer cabinets and doors to achieve Energy Star ratings. DuPont also supplied non-ozone depleting refrigerants.
According to DuPont, there are about six million display cases for food preservation in supermarkets, restaurants, and convenience stores across the United States. Many of those systems still use hydrochlorofluorocarbons, HCFCs, which deplete the ozone layer. The company says DuPont Suva and ISCEON alternative refrigerants have been used to retrofit existing systems and for new equipment.
Partners will participate in a joint industry-government research initiative to assess the performance of green technologies in terms of energy efficiency, reduction of ozone-depleting refrigerant charges, and minimization of refrigerant leaks.
