Figure 4 shows an indoor chiller with a remote air-cooled
condenser on the roof.
1. The discharge gas line runs from the discharge side of
the compressor to the inlet of the condenser.
2. The liquid line connects the outlet of the condenser to a
TX valve at the evaporator.
3. The hot gas bypass line on the circuit runs from the
discharge line of the compressor to the liquid line
connection at the evaporator.
