I have been directed from a room full of geniuses to evaluate 'subcooling' a hallway adjacent to newly installed cooler/freezer equipments.
We are collectively 'stuck' on a renovation project and need to shift equipments around to accommodate 'temporary' usage of cooking/food prep areas. A problem area for this project has been the hallway adjacent to the freezers/coolers with constant condensation issues, partly due to the door being propped open, and the poorly applied visqeen poly sheeting allowing for moist air to enter the space.
next plan of action is to brick up the previously poly sheeted area, add a vestibule/double door set up with an air curtain and to 'subcool' a space to prevent condensation.
I have a compressor rack with a couple of open/ unused circuits, high temp side to 45 deg F that was slated for use elsewhere.
The building we are working on dates to the 50's-60's, located on an Army installation in the Marshall Islands. its constantly hot and humid, WB is 78, with interior hallway temperatures around 80. im sure we could get this down by sealing the building, adding the vestibule.
my plan was to use the existing fan coil unit that was going to go to another room, that wont likely happen for two years in this hallway.
it was sized for a prep room, at 45 deg F, roughly 364 SF; repurposed for hallway at 50-55 (or whenever the sweating stops), roughly 423 SF.
the evap is a russell low volume cooler FL-36-160 putting out 32,000 BTU/hr @ 20 deg temp difference.
i have plenty of reserve on the new refrigeration rack, whereas the future phases are some time away.
My plan was to insulate the walls opposite side of the existing refrigeration coolers. not even sure if this is needed.
i cannot figure if its worth my time and efforts to add an insulated ceiling to the hallway. any path forward is not easy,.
Any input on this hairbrained idea?
