Typically Daikin equipment has been applied using a standard rule of
thumb that a maximum of 20% OA can be incorporated into a ducted
fan coil unit (FXMQ, FXSQ, FXDQ and FXNQ). However, this practice
is not always applicable as this rule of thumb is based upon introducing
OA at nominal conditions.
Basic Rules
1.
COOLING:
Any percentage of OA can be used as long
as the resulting mixed air is between
57 and 77˚FWB
and 80% RH or lower.
2.
HEATING:
Any percentage of OA can be used as long
as the resulting mixed air is between
59 and 80˚FDB
and 80% RH or lower.
Note:
Space temperature sensing should be done via the room zone controller or
remote sensor kit if a “mixed air” approach is taken.
