在提出联邦法规以减少氟氯化碳（CFC）的使用并减少冰箱/冷冻机（R/Fs）的能耗的州，R/F制造商正在考虑替代目前用于R/F柜壁的泡沫和玻璃纤维绝缘材料。请注意，目前正在开发的先进绝缘材料，如真空粉末、真空气凝胶和带有间隔棒的硬真空设计，不含CFC，每单位厚度具有非常高的热阻。因此，它们在使R/F制造商满足这些法规方面显示出巨大的前景。描述了以成本/效益为基础，在R/Fs中模拟这些绝缘的应用，以检查最佳绝缘厚度。 结果表明，从市场营销的角度来看，显著提高绝缘水平是经济有效的，尽管其增加的成本可能很大。薄型先进的隔热材料允许更窄的侧壁厚度和更大的内部体积，因此增加的体积值被用来抵消更高的隔热成本。关键词:隔热、冰箱、冷冻柜、节能、营销成本、经济性。引用:研讨会论文，佐治亚州亚特兰大，1990年

States that proposed federal regulations to reduce chlorofluorocarbon (CFC) use and to reduce the amount of energy consumed by refrigerator/freezers (R/Fs), R/F manufacturers are considering alternatives to the foam and fibreglass insulations now used in R/F cabinet walls. Notes that advanced insulations now under development, such as vacuum powder, vacuum aerogel and a hard vacuum design with spacers contain no CFCs and have very high thermal resistances per unit thickness. Consequently, they show great promise for enabling R/F manufacturers to meet these regulations. Describes the simulation of the application of these insulations in R/Fs on a cost/benefit basis to examine the optimum insulation thickness. States the results suggest that significantly higher levels of insulation are cost-effective from a marketing perspective even though their added cost can be significant. The thin-profile advanced insulations allow narrower sidewall thicknesses and larger interior volumes, so the value of the increased volume was used to offset the higher insulation costs.KEYWORDS: Thermal insulation, refrigerators, freezers, energy conservation, marketing costs, economics.
