(2) Calculation method of heating capacity---Heating capacity to be known
Heating Capacity Modification = Heating capacityx (A x B x C x D x E ) W
(3) Calculation method of refrigeration capacity---Only one indoor unit running
Outdoor modified capacity with a single indoor running=outdoor modified capacity*
