Combination passive cooling for crop storage

Massachusetts Institute of Technologies (MIT) researchers have designed an ground breaking passive cooling process that requires no energy, and only a modest volume of drinking water.

Combining radiative and evaporative cooling with thermal insulation in a slim deal identical to a photo voltaic panel, designers say the system can present up to 9.3°C of cooling from ambient temperature.

The system was made to present passive cooling to preserve foods crops and health supplement standard air conditioners in structures. Researchers say it could maximize harmless food items storage time below humid ailments by 40 per cent, and triple safe storage time in drier climates.

The method makes use of three layers of material – an aerogel, hydrogel and mirror-like surface – which mix to give cooling as heat and water move through the device. By combining cooling technologies that have been used independently of each individual other in the past, designers say the process can deliver considerably extra cooling all round.

The findings were being described in Cell Experiences Physical Science, in a paper by MIT postdoc Zhengmao Lu, Arny Leroy PhD, professors Jeffrey C. Grossman and Evelyn N. Wang, Lenan Zhang of MIT’s Section of Mechanical Engineering and Jatin J. Patil of the Department of Products Science and Engineering.
