The typical household fridge, however, is not designed to work in the absence of Earth\u2019s gravity. From May 4 through 7, 2021, researchers from the small manufacturing company Air Squared, Purdue University, and Whirlpool Corporation completed a parabolic flight campaign with Zero Gravity Corporation in Fort Lauderdale, Florida, to test the gravity independence of a system that could keep food fresh for years at a time.<\/p>\n\n\n\n<p>The vapor compression refrigeration technology demonstration system is about the size of a large microwave oven, though the same cooling technology could be used in refrigerator cabinets several times as large. Designed primarily for food storage, it could also help preserve biological samples for science experiments. Uniquely, its oil-free scroll compressor could make it reliable in any orientation, like upside down or on its side \u2013 an important capability for the variable gravity of lunar and planetary missions.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/fridge_experiment.jpg\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1100\" height=\"619\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/fridge_experiment.jpg?w=1100\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Purdue University Ph.D. student Leon Brendel rotates a highly instrumented fridge experiment designed to work in different orientations\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/fridge_experiment.jpg 1100w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/fridge_experiment.jpg?resize=300,169 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/fridge_experiment.jpg?resize=768,432 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/fridge_experiment.jpg?resize=1024,576 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/fridge_experiment.jpg?resize=400,225 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/fridge_experiment.jpg?resize=600,338 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/fridge_experiment.jpg?resize=900,506 900w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" loading=\"eager\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Purdue University Ph.D. student Leon Brendel rotates a highly instrumented fridge experiment designed to work in different orientations \u2013 even upside down \u2013 to keep food fresh for long durations in space.<\/div><div class=\"hds-credits\">Purdue University \/ Jared Pike<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>Headquartered in Broomfield, Colorado, Air Squared received funding for the refrigeration technology through Phase I and II awards from NASA\u2019s Small Business Innovation Research (SBIR) <a href=\"https:\/\/sbir.nasa.gov\/\" target=\"_blank\" rel=\"noreferrer noopener\">program<\/a>.

The technology\u2019s ongoing research and development is part of the agency\u2019s Advanced Exploration Systems Logistics Reduction and Repurposing project at NASA Johnson, which evaluates technologies that may be useful on future missions to Mars.<\/p>\n\n\n\n<p>Each of the four parabolic flights provided the research team brief periods of microgravity, while also allowing them to be present to tend to their payloads during flight. The team evaluated the vapor compression cycle, a conventional method for cooling in everyday refrigerators on Earth that usually depends on the behavior of liquid and vapor in gravity. This demonstration resulted in the first ever documentation of vapor compression refrigeration in a parabolic or suborbital environment, providing critical data to mature the technology for potential future use on space exploration missions.<\/p>\n\n\n\n<p>\u201cIt\u2019s one thing for us to collect microgravity data and verify that the system is maintaining cooling,\u201d said Dr. Stephen Caskey, principal investigator for the flight demonstration. \u201cBut it\u2019s another thing to identify potential issues and then predict them so we can find workarounds. The feedback we\u2019ve received from NASA and the parabolic testing we\u2019re doing is helping us toward that goal.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>About Flight Opportunities<\/strong><\/h3>\n\n\n\n<p>The Flight Opportunities program is funded by NASA\u2019s <a href=\"https:\/\/www.nasa.gov\/directorates\/spacetech\/home\/index.html\">Space Technology Mission Directorate<\/a> (STMD) at the agency\u2019s Headquarters in Washington, and managed at NASA\u2019s <a href=\"https:\/\/www.nasa.gov\/centers\/armstrong\/home\/index.html\">Armstrong Flight Research Center<\/a> in Edwards, California.
