Table 3:
Minimum capacity (kW) ensuring the oil flowing in vertical sections of the suction line (R410a refrigerant).
The cooling capacity shown in table 3 refer to 40°C of condensing temperature: in case of different temperature values of the liquid
line, the capacities must be adjusted according to the following factors:
Liquid temperature (°C)
30
40
50
Correction factor
1.08
0.91
0.82

Correction factors for different liquid temperature.
Table 4:
Minimum capacity (kW) ensuring the oil flowing in vertical sections of the discharge line (R410a).
In this case also, the cooling capacity shown in table 4 refers to a saturated evaporating temperature equal to -5°C: for different
temperature values the capacity must be adjusted according to the following factors:
Saturated suction temperature (°C)
-20
+5
Correction factor
0.96
1.02
