3. TC, PI and SHC must be calculated by interpolation using the figures in the
above 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. Airflow rate (AFR) and Bypass factor (BF) are tabulated above table.
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 heating capacity (kW) / (kBtu/h)
PI : Power input (kW)
