(1) For interconnecting pipework with a predominantly horizontal layout.
(2) For interconnecting pipework with a predominantly vertical layout.
(3) Careful pipework selection must be done if the liquid line rises. Additional system sub cooling may be required to overcome friction losses.
All pipe sizes have been calculated based on a nominal condition 7°C evaporating and 50°C condensing
Suction and discharge double risers may be required for modulating capacity units at part load.
