Hi all ...
I have a problem here. Could any body please help me?
I want to decrease humidity at the dormitory near shore base, which is very humid (80% - 90% RH; 28 - 32 deg C).
I planned to use centralized dehumidifier, 1 dehumidifier for 6 to 7 room. Every room equiped with 9,000 BTU - 14,000 BTU single split AC (w/o dry mode)
Which one better, open or close system for enviroment like this one.

Thank you for any feedback.
