(c) When the outdoor unit is located at a lower height than the indoor unit in cooling operation and when the
outdoor unit is located at a higher height than the indoor unit in heating operation, the following values
should be subtracvted from the values in the above table.
Height difference between the indoor unit and
outdoor unit in the vertical height difference
Adjustment coefficient
Height difference between the indoor unit and
outdoor unit in the vertical height difference
Adjustment coefficient
(d) Correction of heating capacity in relation to the frost on the outdoor unit heat exchanger
Air inlet temperature of
outdoor unit in ˚C WB
Adjustment coefficient
The correction factors will change drastically according to weather conditions. So necessary adjustment should be
made empirically according to the weather data of the particulsr area.
(2) Correction of outdoor unit capacity according to capacity of indoor unit to be operated simultaneously
