Symbols Note:
AFR : Airflow rate (m3/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 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 : 25ft
Level difference : 0ft
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)

7.3 Capacity correction factor by the length of refrigerant piping (Reference)
The cooling and the heating capacity of the unit has to be corrected in accordance with the length of refrigerant piping. (The distance
between the indoor unit and the outdoor unit)
Note:
The graph shows the factor when additional refrigerant of the proper quantity is charged.
