Figure 3 shows a roof-mounted air-cooled chiller with a remote
evaporator inside the building.
1. There are two refrigeration circuits, each with a liquid
line supplying liquid refrigerant from the condenser to
a TX valve adjacent to the evaporator, and a suction
line returning refrigerant gas from the evaporator to the
suction connections of the compressor.
2. There is a double suction riser on one of the circuits.
Double suction risers are covered inmore detail in the “Oil
Return in Suction and Discharge Risers” on page 21.
