Hello, some very informative posts on this site. I'm new and would appreciate any advice.
The issue: SUPPLY air is reading high humidity around 70%. Even when the space is empty after hours overnight.
The location:
I'm the owner of a 2700 sq ft gym that holds cardio classes.
The workout space is about 1800 sq ft, it has two 4-ton Trane units.
Already investigated:
The units do a good job of cooling the space, even when full.
The units have economizers. We already closed those to test that outside air is not causing the issue.
I have the engineering specs attached here. We haven't done a Test and Balance yet.
We have dehum with reheat coils. But the thing is, the supply air is humid even when no people are present and not as humid outside
Serial number: THC048E3REA1LD0B0A1A0B00AA000C0000000000
The commercial HVAC company I work with has a lot of experience. But they can't figure out, why is the Supply air so humid??
It's causing the mirrors to fog up even when no people are inside the space.
Is this a common problem? Any advice on next steps to investigate or resolve would be great thanks!
