When the air conditioner is running, the refrigerant piping will deform
(shrink, expand, droop). To avoid damage to piping, hangers or
supports should be spaced as per the criteria in the Table 3-4.2. In
general, the gas and liquid pipes should be suspended in parallel and
the interval between support points should be selected according to
the diameter of the gas pipe.
Suitable insulation should be provided between the piping and the supports. If wooden dowels or blocks are to be used,
use wood that has undergone preservative treatment.
Changes in refrigerant flow direction and refrigerant temperature result in movement, expansion and shrinkage of the
refrigerant piping. Piping should therefore not be fixed too tightly, otherwise stress concentrations may occur in the piping,
with the potential for rupturing.
