METHOD OF PRESERVING FROZEN FOOD DURING AN AERO SPACE MISSION

Analyses of three nonelectrical methods for maintaining frozen foods between -10 F and 5 F during aerospace missions of 1 to 28 days are presented. The methods considered are: (1) a heat sink, (2) active refrigeration, and (3) radiation cooling. All method appear feasible. The heat sink method appea...

Description
Summary:Analyses of three nonelectrical methods for maintaining frozen foods between -10 F and 5 F during aerospace missions of 1 to 28 days are presented. The methods considered are: (1) a heat sink, (2) active refrigeration, and (3) radiation cooling. All method appear feasible. The heat sink method appears to be the simplest and most reliable. A design study of a heat sink system for a 3-man, 14-day mission is included.
