Cooling capacity
SYMBOLS
FR: Air flow rate [m3/min.]
BF: Bypass factor
EWB: Entering wet bulb temp. [°CWB]
EDB: Entering dry bulb temp. [°CDB]
DB*: Dry bulb temp. [°CDB]
TC: Total capacity cooling [kW]
SHC: Sensible heat capacity [kW]
PI: Power input (Comp. + outdoor fan motor) [kW]
CAUTION
TC and SHC are given in kW.
V1/V3: 230V [50 Hz]
W1: 400V [50Hz]
NOTES
1
Ratings shown are net capacities. Influence on fan motor heat
is included.
2
shows nominal capacities.
3
SHC is based on each EWB and EDB.
SHC* = SHC correction for other dry bulb.
= 0.29 x 60 x AFR [m3/min.] x (1-BF) x (DB*-EDB)/860
Add SHC* to SHC if SHC > TC, then TC = SHC.
4
Direct interpolation is permissable. Do not extrapolate.
5
Capacities are based on the folowing conditions.
Corresponding refrigerant piping length: 7.5m
Level difference: 0m
