REFRIGERANT PIPING WORK

Selection of Refrigerant Piping Size
The connection piping size for refrigeration unit is, in principle, as shown below, but each
installation should be determined by calculating pressure loss of the piping and refrigerant
flow speed and making sure no problem occurs in the cooling capacity and oil return.
As refrigeration unit using CO2 refrigerant incurs pressure higher than when using
traditional refrigerants, it is necessary to choose adequate materials. Make sure that piping's
are connected to the appropriate pressurized equipment (EN378-2).
