5. Read cooling / heating capacity rate of change in the above figures based on the following equivalent length.
Overall equivalent length=
(Equivalent length to main pipe)×Correction factor+(Equivalent length after branching)
Choose a correction factor from the following table.
When cooling capacity is calculated : gas pipe size
When heating capacity is calculated : liquid pipe size

(Example) RXYQ5PY1, YL
In the above case
(Cooling) Overall equivalent length=80m×0.5+40m=80m
(Heating) Overall equivalent length=80m×1.0+40m=120m
The rate of change in
cooling capacity when Hp=0m is thus approximately 0.79
heating capacity when Hp=0m is thus approximately 1.00

In the above case
(Cooling) Overall equivalent length=80m×0.5+40m=80m
(Heating) Overall equivalent length=80m×0.2+40m=56m
The rate of change in
cooling capacity when Hp=0m is thus approximately 0.87
