Capacity ratio
Piping equivalent length (m)
Total capacity of indoor unit
(2) Method for Obtaining the Equivalent Piping Length
Equivalent length = (length of piping to farthest indoor unit) + (0.3
o
number of bends in the piping) (m)
(3) Correction of Heating Capacity for Frost and Defrosting
If heating capacity has been reduced due to frost formation or defrosting, multiply the capacity by the appropriate correction
factor from the following table to obtain the actual heating capacity.
