1 Determination of input data 1.1 Heat Rejection
N = Installed power in the hydraulic system in kW
Q = Heat Rejection (heat to be dissipated) in kW
Hydraulic pump driven by an electric motor, then
Q = ¾N or 0.75 x N
If there is hydraulic motor in the system, then
Q = N
1.2 V = Oil flow in ℓ/min
1.3 T oil = Oil inlet temperature or maximum allowed Oil temperature in °C
1 4 T amb = Cooling air flow temperature or ambient temperature in °C
1.5 ETD = Entering temperature difference
ETD = T oil ‐ T amb
