4-1. COOLING AND HEATING CAPACITY AND CHARACTERISTICS
4-1-1. Method for obtaining system cooling and heating capacity:
To obtain the system cooling and heating capacity and the electrical characteristics of the outdoor unit, first add up the ratings
of all the indoor units connected to the outdoor unit (see table below), and then use this total to find the standard capacity with
the help of the tables on "4-3. STANDARD CAPACITY DIAGRAM".
(1) Capacity of indoor unit
4-1-2. Method for obtaining the heating and cooling capacity of an indoor unit:
(1) The capacity of each indoor unit (kW)
= the capacity
A
(or
B
)
o
(2) Sample calculation (using the system described above in 4-1-1. (2) ):
model capacity
total model capacity of all indoor units
During cooling: During heating:
• The total model capacity of the indoor unit is:
2.8 + 5.6
o
4 = 25.2 kW
Therefore, the capacity of PKFY-P25VBM-E and
PLFY-P50VLMD-E will be calculated as follows
by using the formula in 4-1-2. (1):
Model 25 = 22.75
o
= 2.53 kW
Model 50 = 22.75
o
= 5.06 kW
• The total model capacity of indoor unit is:
3.2 + 6.3
o
4 = 28.4
Therefore, the capacity of PKFY-P25VBM-E and
PLFY-P50VLMD-E will be calculated as follows by
using the formula in 4-1-2. (1):
Model 25 = 25.19
o
= 2.84 kW
Model 50 = 25.19
o
= 5.59 kW

The following figures are obtained from the 25.2 total capacity of indoor units, referring the standard capacity diagram in
"4-3-1. PUMY-P200YKM PUMY-P200YKM-BS <cooling>" and "4-3-2. PUMY-P200YKM PUMY-P200YKM-BS <heating>" :
