Trane PolyTherm ARTC-SVX005A-EN User Manual

Operating Principles
ARTC-SVX005A-EN 25
In cooling mode, the diverting valves direct the load chilled
fluid to the evaporator and simultaneously direct the
source/sink fluid to the source/sink brazed plate heat
exchanger operating as a condenser.
In heating mode, the diverting valves direct the load
heating fluid to the condenser and the source/sink fluid to
the source/sink brazed plate heat exchanger as refrigerant
has been redirected such that it operates as an evaporator.
In simultaneous heating and cooling mode, the diverting
valves direct the load heating fluid to the condenser and
the load cooling fluid to the evaporator.
Electronic valves on the brazed plate source/sink heat
exchanger outlet modulate to control refrigeration head
pressure. Electronic valves on the evaporator and
condenser outlet also allow for variable flow. See Figure 9,
p. 24 and Figure 10, p. 25.
