Researchers at the Politeknik Negeri Ujung Pandang in Indonesia have proposed the use of vacuum pressure to reduce the operating temperature of PV modules. The passive cooling method involves a casing ...

Atmospheric air will enter a refrigeration system any time it is opened for service or any time a new system is being assembled. Atmospheric air contains nitrogen, oxygen, and water vapor, all of ...

Vacuum cooling is an innovative and rapid cooling technology that utilises the principle of evaporative cooling under reduced pressure to decrease the temperature of moist, porous foods efficiently.

Vacuum technology is used in a wide range of industries, and proper use depends on accurate measurement devices, or gauges. Vacuum gauges work by detecting changes in pressure and converting those ...
