What (who) is vacuum cooling - definition
Vacuum cooling
RAPID COOLING TECHNIQUE USING THE PRINCIPLE OF EVAPORATIVE COOLING
Vacuum cooling is a rapid cooling technique for any porous product that has free water and uses the principle of evaporative cooling. Vacuum cooling is generally used for cooling food products that have a high water content and large porosities, due to its efficacy in losing water from both within and outside the products.

MANAGEMENT STRATEGY FOR GLOBAL WARMING
Passive radiative cooling; Daytime passive radiative cooling; Daytime radiative cooling
Passive daytime radiative cooling (PDRC), passive radiative cooling (PRC), or terrestrial radiative cooling is a solar radiation management strategy that has been proposed as a solution to global warming which involves the mass installation of sky-facing surfaces on Earth that reflect heat to outer space to reverse local and global temperature increases while requiring zero energy consumption or pollution. Because all materials in nature absorb more heat during the day than at night, PDRC surfaces are designed to maximize the efficiency of both solar reflectance (in 0.
Immersion cooling
IT COOLING PRACTICE
User:Dpope83/Server Immersion Cooling; Draft:Server Immersion Cooling; Server Immersion Cooling; Server immersion cooling; Immersion Cooling
Immersion cooling is a thermal management technique, often applied as an IT cooling practice, by which electronic devices and IT components, including complete servers and storage devices, are submerged in a thermally conductive but electrically insulating dielectric liquid or coolant. Heat is removed from the system by circulating relatively cold liquid into direct contact with hot components, then circulating the now heated liquid through cool heat exchangers.
