2-3. Cooling / heating capacity characteristics

2-3-1. Correction charts for cooling capacity calculation
[1] Capacity correction value vs. indoor air wet bulb temperature
[2] Capacity correction value vs. outdoor air dry bulb temperature
[3] Capacity correction value vs. connecting pipe length and lift difference between indoor and
outdoor units
[4]* Correction of outdoor unit diversity
* : Coefficient to use for correction of outdoor unit capacity when total capacity of the indoor units are not equal to the outdoor unit
capacity.
