HI everyone I haven't been on here in a while due to being sent overseas, I've got a problem i'm hoping one of you can help me with,I need to find out what size BTU window shaker I would need for rooms that are 10 by 10 and would hold one or two soldiers. these are sleeping accomodation.I am dealing with up to 50 degree celsius temperatures here and I want to make life a little better for the guys, some rooms have old window A/C in them but they are 17,500 btu I think these are way oversized as they make the rooms feel damp and they run and shut off over and over. Any help you could offer would be great.
