1. INTRODUCTION
A newly developed SAMSUNG side by side refrigerator in 2002 has the following
characteristics.
1) Twin Cooling System
The refrigerator and the freezer have two
evaporators. Given this independent system, the
freezer and the refrigerator are cooled individually as
required and are, therefore, more efficient. Food
odor from the refrigerator does not affect food in the
freezer due to separate air flow circulation.
2) Multi-Flow System
Cool air circulates through multiple vents on every
shelf level. This provides even distribution of cooling
inside cabinets to keep your food fresh longer.
3) Xtra SpaceTM
Vertical room next to the ice maker in the freezer
provides space for pizza etc.
4) Door Alarm
Beep sound reminds you the door is open.
5) Xtra FreshTM
Optimized humidity control keeps vegetables & fruits
fresh.
6) Deodorizer
Reusable deodorizer keeps the refrigerator air
fresh and odor free.
7) CoolSelect ZoneTM Drawer (Optional)
User can select Quick Cool, and Select for quickly
soft freeze, chill, and cool. Select Soft freeze,Chill or
Cool to control the temperature of the drawer.
