When the load increases the velocity of the refrigerant ensures that oil carries up both tubes. Care must be taken in sizing double riser systems. CAUTION EasiCool Technical Manual 7525389 V1.8.0_05_2016... - Page 43 Liquid Line If the system is configured with the EasiCool higher than the condenser unit it may be required to increase the degree of sub cooling to prevent flashing gas occurring in the liquid line. This flashing is due to excess pressure drop caused by the static head of liquid refrigerant and can results in poor operation of the evaporator and expansion device.
