Piping length : Main 2.5 m, Branch 2.5 m/2.5 m
The unit of pressure has been changed to MPa based on international SI system.
The conversion factor is: 1 (MPa) = 10.2 (kgf/cm²)
3-5. CAPACITY CORRECTION (Refrigerant piping length)
Cooling and heating capacity is lowered according to the piping length. Capacity can be obtained by referring to the following
capacity curves.
Corrected pipe length (m) = actual pipe length (m) + number of bends × 0.3 (m)
