This new Arctica dual evaporator refrigerator has the following features:
• Separate freezer and fresh food evaporators with independent cooling.
• No damper/air inlet assembly in the fresh food section creates more usuable space on the
top shelf.
• Greater fresh food humidity to keep food
fresher, longer.
• 20% less freezer defrost for better food
preservation.
• 3-Way valve to direct refrigerant flow.
• Nearly silent, only 30 dBA.
The 3-speed compressor is controlled by
an inverter that receives input from the
low voltage DC side of the main control
board. The inverter always has 240 VAC
applied when the refrigerator is connected
to power. The main control board still makes
compressor decisions based on the input of
thermistors, door-open time, and input from
the temperature control panel. The main
control board also operates the condenser
fan, fresh food fan, freezer fan and adaptive
defrost.
The most significant difference from previous
models is that the freezer and fresh food
evaporators are separate. The 3-way valve
directs refrigerant flow to each evaporator as needed. The fresh food section no longer relies on the
freezer evaporator for cooling. The evaporators are controlled separately by the main control board
through the 3-way valve.
