Dana, et. al.
I am hoping to have my existing Trane HVAC residential system replaced with one that can help control humidity better on days when humidity is high but temps are near or below the set point.
There is not enough space in the 'furnace room' for a whole house dehumidifier to be installed in parallel with the HVAC system.
To me it looks like a system comprising a Trane air handler (for reasons given below) with an A/C coil and a hydronic heating coil fed by a tankless W/H could work in our environment. It's rarely very hot or very cool... just humid above 50% RH most of the time.
It seems to me that, if some sort of smart thermostat exists that can control this system appropriately, the system can be made to function as a whole house dehumidifier on these 'shoulder days', as I've learned they are called.
In theory, when in dehumidify mode, the A/C coil would remove water (but also cool the air below the set point) and the hydronic coil would rewarm the air back up to the set point (actually lowering the RH ever further).
I've scanned brochures for other major brand systems, but the only one I found so far where the hydronic coil is downstream of the cooling coll is the Trane Hyperion air handler.
So, my two questions are: 1) can the system described above really act as a whole house dehumidifier during shoulder days, and 2) are there additional brands where the (re) heating coil is inserted after the cooling coil?
Thanks!
