IS IT CORRECT,
The reheat coil of FAHU does not reduce the humidity, but increase the sensible load and maintaining the relative humidity by increasing the dry bulb. Same like slightly increasing the dew point temperature also.
I don’t know whether my question is dumb, when increasing the dew point, increasing the possibility of condensing the water in side the air conditioned area and the chance to damage the chilled water insulation. Right now I am facing a humidity issues, it damaged entire 4 year old chilled water insulation and water is dripping everywhere. Location is island, high humid area. Maximum ambient will reach 52c and some time wet bulb will go above30c.
During the first inspection, I found the FAHU Johnson controller FX15 setting is 80%RH and leaving temp set point24c. Re-stetted to 50%RH and 22c.we are going to replace the insulation.
Your any valuable comments highly appreciated.
