2-1) Introduction of main function

● A newly developed SAMSUNG side by side refrigerator in 2005 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 twin deodorizers keep the refrigerator air

fresh and odor free.

7) CoolSelect ZoneTM Drawer(RS267, RS269)

● User can select Quick Cool, Thaw, for quickly chill

items, thaw items. Select Soft freeze, Chill or Cool to

control the temperature of the drawer.

11. CIRCUIT DESCRIPTIONS

11-1) Source Power Circuit

This circuit shows SMPS(Switch Mode Power Supply) which converts AC input voltage (115V, 60Hz) to a high DC voltage
(170V). The input AC source power is converted to DC through a wave rectifier (BD1) and the converted DC power will
generate a constant waveform on the switching transformer using a high speed (100KHz) switching motion of TOP223Y.
The D104 will rectify the generated voltage and transform into a steady 12V DC source power used for the digital display
panel and relays. The regulator (KA7805) finally transforms into 5V DC source power for the control board and sensor’s
circuits.

Caution) Be careful to handle this circuit due to high voltages (AC115V, DC170V)

11-2) Oscillator Circuit

Terminal Oscillation Frequency

Xin(#30) 4MHz
Xout(#31) 4MHz

This is oscillator circuit to generate synchronous clocks used to calculate the time for the microprocessor operation.

Note) If the specification of resonator changes, micro-processor can not work properly.

11-3) Reset Circuit

11. CIRCUIT DESCRIPTIONS

11-6) Key Scan and Display Circuit

1) Key Scan and display operation.

The model uses a decorder IC which 4 inputs and 9 outputs.

If the IC 9 decorder (TC4028BP) received signals from
MICOM pins (3∼6), an output signal per 2 miliseconds
comes out from Q3, Q41, Q8, Q6, Q9, Q7, Q0, Q2, and Q4
pin in sequence. This signal enters to a driver IC input
terminal of the CoolSelect ZoneTM PCB and IC5 (TD
62783AP), then approximate 11V peaks will generate from
an output terminal as shown on the next page.

78
11. CIRCUIT DESCRIPTIONS

The step signals of DC 11∼ 12V will be generated periodically. If a sink signal outputs from IC4, DC 11-12V will be
applied to the LED input terminal and sink the LED output terminal to 0V. Therefore, LED will be ON for 2 miliseconds.

2) Key Scan
The 6 step signals, Q6∼Q4 are applied to scan the 6 keys (buttons). When SW6 is pressed, the step signal from Q6
will be reduced to 5V and entered to the MICOM, then MICOM will match a corresponding function for SW6 key.

close. So cold air is supplied only to CoolSelect ZoneTM Drawer. For Thaw, the evaporator heater of refrigerator is
ON and the damper is controlled by the refrigerator temperature.
2-2) The stepping motor controlled by a Driver IC TA7774P(IC7) operates the damper. The stepping motor uses 4
combined signals to open and close the damper.

Note) To prevent the malfunction from a high humidity, a Dc12V, 1 watt heater is mounted and activated continuously.

11-8) Fan Motor (BLDC) Drive Circuit

1) Motor drive circuit

11-11) Load Drive Circuit

1) The control of load in the system is accomplished by the main PCB.

2) Most of relays or SSRs can control compressor, refrigerator/freezer defrost heater, and several option functions.

3) For compressor, #18 pin of micro processor signals High (5V). This signal inputs #5 pin of IC3 and #14 of output
terminal which have base and collector functions of IC3 turns on and connects the GND. Relay 73 will be grounded
through #14 of IC. Magnetic lines will generate so that the second side of RY73 is activated and 115V is supplied to
the compressor. On the other hands, if #18 of micro processor turns Low(0V), #5 of IC3, the current of RY 73 relay,
and magnetic line will shut down in sequence. A contact point in secondary side of Relay 73 is off. Finally compressor
will stop.
