ASTM E595 outgassing test, This test method covers a screening technique to determine volatile content of materials when exposed to a vacuum environment.

Water continually evaporates, condenses, and precipitates, and on a global basis, evaporation approximately equals precipitation.

With the increase of inlet air temperature of the condenser, evaporation pressure, condensation pressure increase, but supercooling and superheat degree, refrigerating capacity and COP decrease.
