Table 18: LC367HV System Cooling Capacity Table.
TC = Total Capacity (kBtu/h).
SHC: Sensible Heat Capacity (kBtu/h).
PI = Power input (KW). Power input (KW) includes compressor and fan(s).
Nominal capacity as rated 0 ft. above sea level and a 0 ft. level difference between outdoor and indoor
unit. Corresponding refrigerant piping length is accordance with standard length of each outdoor unit.
Nominal cooling capacity rating obtained with air entering the indoor unit at 80ºF dry bulb (DB) and 67ºF
wet bulb (WB), and outdoor ambient conditions of 95ºF dry bulb (DB) and 75ºF wet bulb (WB).
The shaded table rows indicate reference data. When operating at this temperature, these values can
be different if the system is not running consistently.
