※ Accordance with product type(operation mode), target region, model line up could be different.
Apply the correction factor after selecting that according to the unit capacity.
■ Calculation Example for overall equivalent length
* Installation condition : Model capacity = 8HP, Main pipe length = 30m, Branch pipe length = 30m, HU=0m
(Maximum pipe length and limit condition will be different by each model. Use this example only for reference.)
: Overall equivalent pipe length for Cooling = 30m x 0.5 + 30m = 45m
: Overall equivalent pipe length for Heating = 30m x 0.2 + 30m = 36m
* The rate of change in
Read the correction factor value condition on length = 45m and HU = 0 in Cooling correction factor table.
Read the correction factor value condition on length = 36m and HU = 0 in Heating correction factor table.
