注意到美国能源部对替代化合物和技术的能源效率影响的担忧，这些化合物和技术可能被用作CFC11和CFC12的替代品，作为制冷剂和发泡剂。讨论了使用替代化合物替代CFC可能导致美国能源使用量增加的问题。得出的结论是，能源使用可能会显著增加，尤其是在冰箱/冰柜、热水器和商业建筑中。关键词:能源消耗，美国，制冷，冰箱，R12，冷冻机，热发泡剂，泡沫，隔热，美国，R11，制冷剂，隔热。引用:研讨会论文，佐治亚州亚特兰大，1990年

Notes the concern of the US Department of Energy about the energy-efficiency impacts of alternative chemical compounds and technologies that may be used as substitutes for CFC11 and CFC12 as refrigerants and blowing agents. Discusses the possible increase in US energy use resulting from the replacement of CFCs with alternative compounds. Concludes that significant increases in energy use could occur, particularly in refrigerator/freezers, water heaters and commercial buildings.KEYWORDS: Energy consumption, USA, refrigeration, refrigerators, R12, freezers, thermal foaming agents, cellular, thermal insulation, USA, R11, refrigerants, insulation.
