It depends on many parameters
normally to attain22 Deg C Supply Air temperature can be from15 -19 Dec C.
If we reduce the Supply air temperature load on coil will be increased and coil size may be bigger but required CFM and duct size will be reduced and vice versa
According the psychometric chart the recommended Supply air temp. from 12 to 14C to remove all water from the air before supply it to room.
Fcu grill temperature kya hota hai
Supply air temperature or Off coil temperature varies between 12 to 14.5 degree celsius. Refer the FCU supplier selection schedule to know the range for a aprticular FCU , selected based on dfifferent parameters.
Supply air could not be controlled either it will be very warm or cold it depends upon the place where you stay but the system could be protected by thermostat installed in the air inlet of the the system if set to a certain temp. usually set to lower temp. to stop the system when too much cold air will be detected.
