Operating Principles
The PolyTherm Simultaneous Chiller/Heater is a state-
of-the-art six-pipe multipurpose system (See
) featuring independent water circuits to satisfy
end user's requirements for heating and cooling year-
round. It eliminates the need for duplicate equipment
and significantly reduces space requirements by
combining duties and reducing glycol requirements.
Figure 7. PolyTherm simultaneous chiller/heater
The PolyTherm Chiller/Heater is designed to operate
with a water/glycol mixture to prevent rust, scaling,
and organic growth and uses R-410A or R-134a
refrigerant.
The simultaneous heating and cooling system is
designed to operate in heating mode, cooling mode, or
simultaneous heating and cooling based on the system
demand by opening and closing electronic diverting
valves on the evaporators, condensers, and the source/
sink heat exchanger and redirecting refrigerant flow to
the operating brazed plate heat exchangers.
