1.9.2 Correction of cooling and heating capacity in relation to air flow rate control
(fan speed)
1.9.3 Correction of cooling and heating capacity in relation to one way length of
refrigerant piping
It is necessary to correct the cooling and heating capacity in relation to the one way equivalent piping length between the indoor
and outdoor units.
Note (1) Calculate the equivalent length using the following formula.
However, install the piping so that the piping length is 5 m of the limit length (actual length) for the respective types.
• Equivalent length =Actual (Equivalent bend length x number of bends in the piping.)
