Pressure Drop Curves - Daikin AGZ 025D Operating & Maintenance Manual

Pressure Drop Curves

The pressure drop for any given unit is the same regardless of constant or variable flow. Only the
lower cutoff point for minimum flow will change.
Table 8 on page 11 contains the evaporator reference letter and the minimum and maximum flows
allowed for each unit. Occasionally the same evaporator is used on multiple units resulting in
overlapping lines.
The nominal and maximum flow and pressure drop are the same for a given unit size regardless of
having fixed or variable flow.
The curves are based on water use only. Use glycol adjustment factors located in the catalog
Performance Section as required.
