Example: Unit with liquid and gas pipes of 10 m real length each. The nameplate of the unit states a base load of
9 kg of the R410A refrigerant. The installed liquid line is of 3/4", the chart states 2,36 kg
. The gas line is of 1 3/8”
and the table states 241 g=0,241 kg, therefore we calculate that the total quantity to be loaded is: 9 + 2,36 + 0,24
=
11,6 kg
of R410A.
The same result can be obtained by using the gram information per meter of the gas and liquid pipes stated in
the chart: (236+24) and multiplying by the meters (10 m): 236*10 + 24*10 = 2600 g =
2,6kg
. We will calculate
again the total value by adding this value to the base load: 9 + 2,6 =
11,6 kg
.
