This paper will present the results from the breadboarding phase conducted for the Crew Refrigerator/Freezer Rack project. The Refrigerator/Freezer Racks are designed to supply the International Space Station crew with fresh and frozen food on-board the station and to transport food from ground to the station in the Multi Purpose Logistic Module (MPLM).

Currently a Refrigerator/Freezer Rack (RFR) for theInternational Space Station (ISS) is developed by Daimler-Chrysler Aerospace. The Refrigerator/Freezer System consisting of a pool of 10 flight racks in total, with a 3 racks complement always on-orbit, will provide the necessary conditioned volume for the crew’s frozen and refrigerated food as well as for other cargo items requiring conditioned stowage. The Mini Pressurized Logistics Module (MPLM) will be utilized for upand download logistics. Either the racks or the cargo only will be swapped from the MPLM to the ISS and back again. In the following section the preliminary RFR design concept as a result of a Phase A study will be presented.
