A gravity-free space refrigerator can keep astronauts' food fresh for years.
[Obrázky: groll-brendelLO-1.jpg]


Regular procurement keeps astronauts aboard the ISS supplying fresh food. But flights to Mars will not be delivered. If we were to visit other planets, we would need an unbreakable refrigerator in space - Purdue University researchers are doing heavy testing.You might think that there is nothing to prevent a normal refrigerator from working in space. It sucks out the heat and makes the air cool easily, right? But fridges rely on gravity to distribute oil through temperature-controlled compressor systems, so these systems don't work or crash quickly in space.

The solution, run by the ดาวน์โหลดสล็อต xo Purdue team and partner maker Air Squared, is a traditional, oil-free refrigerator that will function regardless of the direction or magnitude of gravity. It was funded by NASA's SBIR program, which funds promising small businesses and trials to equip them with mission-ready. (The program is currently in the process of extending the 2nd prize period)In two years of development, the team finally assembled a ready-for-flight prototype, and last month was finally able to perform a small gravity test simulated in a parabolic plane.The initial results are promising: the refrigerator works.

The fact that the refrigeration circuit was running continuously in the microgravity during testing without any problems indicates that our design was a very good start," said Leon Brendel, Ph.D., a student on the team. "Our first impression is that small gravity doesn't change the cycle in ways that we are not aware of.Short term gravity (The prototype weighs only 20 seconds at a time) is just a limited test, and it certainly helps shake off any problems with the equipment they're working on. But the next test could be a long-term installation aboard the International Space Station, where residents will no doubt want to have a working refrigerator.

While expecting cold drinks and frozen food (But not drying) is tantalizing, but a simple refrigerator can be used for all sorts of science works, too. Experiments requiring a current cold environment can either use a complex micro-refrigeration mechanism or use a near-absolute space environment. So it comes as no surprise that NASA had them join the Mini Gravity Simulator as part of the Opportunity to Flight program.Analysis of the data collected on the flight is ongoing. But the success of this first large-scale test validates both the approach and the operation of the space refrigerator. Next up is to find out how it will function in the confined spaces and steadily small gravity of the International Space Station.
