Symbols: Note:
AFR : Airflow rate (m
3
/min.) 1. Ratings shown are net capacities which include a deduction for indoor fan
motor heat.
2. shows nominal (rated) capacities and power input.
3. TC, PI and SHC must be calculated by interpolation using the figures in the
tables. (Figures out of the tables should not be used for calculation.)
4. About SHC which are not mentioned on the table, please calculate them with
around values in direct proportion.
5. Capacities are based on the following conditions.
Corresponding refrigerant piping length : 25 ft
Level difference : 0 ft
6. Cooling capacity at
–15°CDB and 5°FDB.
BF : Bypass factor
EWB : Entering wet bulb temp. (°C) / (°F)
EDB : Entering dry bulb temp. (°C) / (°F)
TC : Total capacity (kW) / (kBtu/h)
SHC : Sensible heat capacity (kW) / (kBtu/h)
PI : Power input (kW)
Temp: Celsius
