Operating Principles
The PolyTherm Simultaneous Chiller/Heater is a state-of-
the-art six-pipe multipurpose system (See figure below)
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.
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.
