1-3.Model selection
(１)
Model selection method
The performance curve of dew point as mentioned above are shown the relationship
between output air pressured dew point on condition that inlet air pressure is 0.7 MPa and
its temperature is 25℃(saturated). Se
lect the model on the right of the intersection of the
required dew point and the required flow.
<Correction method of air flow>
It is necessary that output air flow shall be corrected by each correction curve, except for
rated conditions.
（Rated output air flow）×（Correction factor）＝（Output air flow）
But, in the case of the air by which input air passed along the refrigerated drier,
select inlet air temperature as 10 ℃ regardless of an actual temperature.
（例）Required dew point :
15℃
Required air flow : 100
/min(ANR)
The model ① which is located on the right of
the intersection shall be selected.
（例）Inlet air pressure : 0.85Mpa
Required dew point :
20℃
Required air flow : 120
/min(ANR)
１．
The correction factor 1.2 shall be read from
outlet air flow correction curve against inlet
air pressure.
２．
The model ② shall be selected flow
performance curve of dew point, since outlet
air flow is 120
/min ANR
(=100
/min ANR×1.2)
（２）
Purge flow
Purge flow is shown in each specification
column. The flow which added purge flow to
outlet side use air flow should be can be
supplied from an inlet.
Purge flow in case inlet air pressure differs
from rating turns into flow which applied the
correction factor of the right to rated purge
flux
.
