Dear Sir,

I have 3 rooms and 1 AHU.
two room temp is 27+/-2, humidity 55+/-5%
another room trmp is 22+/-2, humidity 55+/-5%
ambient is 17

then what i have to do for controlling temp of all 3 rooms.

let me explain AHU type.

room return air + fresh air(through 10 micron filter) -> mixing -> cooling and heating coil -> 10 micron filter -> 5 micron filter -> fan -> duct -> terminal HEPA.

lamina air flow from HEPA tp RISER.

please give answer.

Dear Sir,

I have 1 AHU which supplying air to 4 rooms.

I want 20 degree temp. in 1 room and 25 degree in another room.

Is it possible???

please reply ASAP.

Thanks

Dear Ashok,

Kindly first let me know the ambient temperature of the room with out AHUs working and ambient out side the rooms temperature. Also let me know AHU design lay out (Ducts lay outs) with air pattern and is there any %RH requirement? then i can help you in this regard,

Thanks

Yes it is possible. Of course it depends on the design. Some designs have reheat coils before a duct enters a room to bring the supply temperature up. There are other parameters involved too (fresh air system or recirc?)

Here’s a question - why? why do you need the lower temperature? Can the other room operate at the lower temperature?
