* In case of selection based on Total Heat Load and Sensible Heat Load, select indoor units which satisfy not only the Total Heat Load but also
the Sensible Heat Load of each room. The sensible heat capacity of indoor units is to be corrected for indoor air temperature. If the design
temperature of indoor air falls between temperatures listed in table, calculate sensible heat capacity by using the bypass factor calculated by
interpolation for each indoor air temperature.
[3] Selection of outdoor unit
[3] –1 Define the required total heat load from the indoor units to the outdoor unit
Define the required total heat load (A) based on (1) the sum of the peak load of each room or (2) the system peak load.
In this example, select an outdoor unit by (2).
Therefore, (A) = 173.0 MBH
