R2E Point 5 mini safe room cooling / ventilation

This document outlines proposed cooling and ventilation options for the mini safe room, as discussed on April 26, 2013, during a brainstorming session with various teams (EN/EL, EN/CV, GS/SE, MEF-INT, R2E). Four options were presented: 1) Air cooling via apertures at the base, 2) Pulsed air from UTAs below the metallic structure, 3) Safe room repositioning for optimal duct alignment, and 4) Lateral air pulsing through new ducts from UL557. Each option includes actions for model display and efficiency calculations.

  2. OPTIONS proposed on Friday 26th April (brainstorming EN/EL, EN/CV, GS/SE, MEF-INT, R2E team) Option 1: cooling ensured via apertures of 120 mm or 100 mm located at the bottom of the equipment (@ the level of the metallic structure of the safe room) along the whole safe room (18m); air pulsed from UTAs (?) located in UL557. Actions: - EN/MEF: show the corresponding models; - CE: check the feasibility, number of ducts and distance in between; - R2E: discuss the integration feasibility with GS/ASE-DI/ODH team; - CV: calculate the efficiency of such a cooling (UTAs located in UL557- machine side) Option 2: cooling = air pulsed below in the metallic structure from UTAs located in UL557; 2 additional ducts to be drilled in the wall between UL557/UL558 and UL557/CMs to ensure air arrival from UTAs; cables would arrive from top in between equipment in safe room to liberate as much as possible space below the equipment in the metallic structure. Actions: - EN/MEF: show the corresponding models; - CV: calculate the efficiency of such a cooling (UTAs located in UL557- machine side)

  3. OPTIONS proposed on Friday 26th April (brainstorming EN/EL, EN/CV, GS/SE, MEF-INT, R2E team) Option 3: Safe room moved as close as possible to its initial location (when position of the ducts was decided). Cooling ensured via primary solution proposed by CV. Actions: - MEF-INT: show the corresponding models; - CV: calculate the efficiency of such a cooling ; Option 4: Cooling ensured via lateral air pulsed from UL557 via a new duct to be drilled close to the safe room; need to relocate a vertical cable tray; UTAs located in UL557. Actions: - MEF-INT: show the models; - CV: calculate the efficiency of such a cooling ;
