Cassette A/C Unit

Dear Sir,

Your problem needs more input parameters.

(1) Where are the units located ? Coastal area or very hot climate ?

(2) Why do you need 22 deg ( Cent) ? Any process or other conditions like a

medical lab?

(3) Is the area is highly humid Or the area between false ceiling & the roof

prone to moisture ?

(4) Do you have enough gas volume & pressure ? low gas may lead to frosting.

(5) Is there any way to keep the area ( refer 3 ) dry by having any natural

ventilation or exh.fans ?

(6) Any damaged gas line insulation ? Are the drain lines from the units have

reqd slope Or any drain line choke up ?

I am not an HVAC man but these points are common in any system.

hai,

can u please suggest me for the best insulation what should be used ,make ,company ,vendor in hyderabad.

I assume from your description that chilled water is taken to the FCU type ( Cassette type mounted above the false ceiling. Following are few causes

Insufficient or damage insulation of Chilled water piping.

Air leakage above the false ceiling

Infiltration of humid air into the A.C area.

Check the pipe was Insulated or not, it may be chill water or direct refrigerant system.

Then check for condesate drain line, try to use p trap in drain line
