ACMV Condensation in the toilet

[darrenyee88]

Hi,

I encounter issue where the Female toilet as shown in the image is encountering condensation and moisture are all round the wall and toilet doors.
The design can be seen to have TEAF and also FCU supply . the temp is set at 24 Deg C.

Can any expert advise the cause of such condensation.
Thanks.

Questions:
[ul]
[li]What temperature is set to 24C? the supply temperature or the room temperature?[/li]
[li]Are all pieces of equipment operational?[/li]
[li]what is LAT off FCU?[/li]
[li]Where is the FCU pulling from?[/li]
[/ul]
possible issues:
[ol 1]
[li]FCU could be malfunctioning, either not blowing or cooling. Either of these would allow room humidity to rise.[/li]
[li]FCU could be pulling from a location with high RH but low DB temperature, this would mean that a temperature based control for FCU cooling coil will do nothing to cut down humidity. (try lowering the temperature set point)[/li]
[li](unlikely) Fan could be spinning wrong way and pushing humid air into space? bathroorm and surrounding areas would be smelly if this is the case.[/li]
