Storage processes cooling

Of these systems, heat pump supported combined heating and cooling applications (system B) are dominating. However, in recent years, there is a growing interest for storage of natural cold (system D), which is used for district cooling applications or for industrial process cooling.

Major facilities as defined herein included process units, storage facilities, cooling water systems, and steam systems. 

If ambient conditions normally exceed about 50% RH for extended periods (more than about 8 h), provisions should be made to dehumidify the process plant and bulk storage buildings. Cooling and proper ventilation may also be necessary for worker comfort and safety. Adequate ventilation is especially important because all buildings should be tightly constructed and closed to maintain a dry inside environment (RH of 40%-50%). 

Location for installation in plant—on grotmd floor or on roof The latter needs a strong roof, bnt can serve as a storage of cooled water for emergency use in process plant. 

Radioactive effluents and wastes were generated in a variety of process systems. These radioactive wastes included reactor primary coolant water, spent fuel storage basin cooling water, reactor periphery systems cooling water, reactor primary-coolant-loop decontamination and rinse solution, and miscellaneous drainage from reactor support facilities (WHC 1987a). 

The writing process, that is, the transition crystalline — amorphous, is caused by briefly (<50 100 ns) heating up the selected storage area (diameter (( )) ca 0.5—1 Hm) by a laser pulse to a temperature above the melting point of the memory layer (Eig. 15, Record), such that the film locally melts. When cooled faster than a critical quench rate (10 -10 ° K/s), the formation of crystalline nuclei is suppressed and the melted area sohdifies into the amorphous (glass-like) state.
