SERIES M

Valve size calculation for the liquid line

Refrigeration capacity Q0, multiplied with correcting factor fTF, multiplied with correcting factor f PF results in the required nominal capacity QN.

QN = Q0 x fTF x f PF

QN nominal capacity (according to table on page 2) Q0 refrigeration capacity

fTF correcting factor for evaporating and liquid temperature

f PF correcting factor for pressure loss across the valve

Correcting factor fTF for the change of capacity according to the operating temperatures
