Economiser System
Evaporator
Adopting a compact design with a compact footprint and a significant reduction in refrigerant charge when compared to
a flooded evaporator equivalent. The evaporator incorporates an intergrated subcooler as standard, further boosting its
performance over other heat exchanger technologies.
Condenser
The similarly designed condenser also adopts the compact design, reducing footprint and refrigerant required for
subcooling.
Economiser
Via the economiser, a portion of the refrigerant is evaporated and used to further sub cool the bulk of the liquid
refrigerant via a plate heat exchanger. This extra sub cooling lowers the liquid refrigerant enthalpy allowing for a higher
ratio of heat absorption in the evaporator; the overall effect is an increase in cooling capacity.
Should the option be selected refrigerant will flow through the economiser before the integrated subcooler, this will
provide a reduction in liquid temperature prior to the subcooler which in turn shall reduce the level of additional suction
superheat generated by the integrated subcooler.
