Abstract
Recent developments in advanced insulations, such as powders under a soft vacuum (R=20 per inch), and hard-vacuum insulation with spacers (R= 15 per 0.1 inch), merit evaluating their practical uses. Refrigerator/freezers (R/Fs) are well-suited for incorporating the new insulations for the following reasons: the energy consumption of R/Fs must be reduced to comply with the National ApplianceEnergy Conservation Act (NAECA) standards; the Montreal Protocol to Control Ozone-Depleting Substances calls for a reduction in chlorofluorocarbons (CFCs) that are now used in the insulative foams in R/F sidewalls; and both high R-values to minimize heat gain through the walls, and thin walls to maximize the interior volume, are desirable.
