2. REFRIGERATION CYCLE

Mechanical refrigeration is accomplished by continuously circulating, evaporating, and condensing a fixed supply of refrigerant in a closed system. Evaporation occurs at allow temperature and pressure while condensation occurs at high temperature and pressure. Thus it is possible to transfer heat fom an area of low temperature (i.e., refrigerated compartment) to an area of high temperature (i.e., surrounding of refrigerator).

CONDENSER

CAPILLARY TUBE

COMPRESSOR

EVAPORATOR

THE BASE REFRIGERATION CYCLE

Beginning the cycle at the evaporator inlet the low pressure liquid expands, absorbs heat (so refrigerator inner-cabinet is cooled), and evaporates, changing to allow low pressure gas at the evaporator outlet.

The compressor pumps this gas from the evaporator, increases its pressure, and discharges the high pressured- temperature gas to the condenser.

The condenser lets high pressured- temperature gas emit the heat (so surrounding of the condenser is warmed) in order to make it condense.

The capillary tube prevents high pressured- temperature liquid from entering the evaporator in order to lower the pressure in the evaporator and control the flow of refrigerant into the evaporator automatically.

Eventually the desired air temperature in refrigerator inner-cabinet is reached, the thermostat (temperature controller) will break the electrical circuit to the compressor motor and stop the compressor.

- 9 -

As the temperature of the air rises, the thermostat (or controller) remakes the electrical circuit. The compressor starts, and cycle continues.

The schematic refrigeration (or freezing) cycle of F23/F49/F72/R23/R49/R72/GR26/GR48/GR70 is like below.

9) CHECKING SENSOR

Sensor assembly consists of T-sensor (lead wire: orange) and D-sensor (lead wire: blue).

The T-sensor is used for cabinet temperature control and the D-sensor is used for defrost control.

The resistance of the sensor varies depending on temperature.

If you Immerse the sensor in a glass containing ice water for 2 minutes and then check for the resistance between sensor leads, the normal reading is 7.88 ㏀ (T-sensor) / 30 ㏀ (D-sensor).

1. OPERATION FOR F23/F49/F72(FREEZER), R23/R49/R72(REFRIGERATOR)

1) BASIC OPERATION

① Plug in the power cord and turn on the power switch located on the bottom of the top grille right side.

[ The unit should be plugged into a 115V±10%, 60Hz (F23, F49, F72, R23, R49, R72 models) ]

② Display panel will be lit for 2 seconds with buzzer then displays cabinet interior temperature (T-sensor) and running conditions.

* Freezer : If cabinet interior temperature is higher than 14℉ (-10℃) compressor will run without

delay, and lower than 14℉ (-10℃), compressor will run after 3 minutes.

* Refrigerator : If cabinet interior temperature is higher than 50℉ (10℃) compressor will run

without delay, and lower than 50℉ (10℃), compressor will run after 3 minutes.

③ The default OPERATING TEMPERATURE SETTING

* Freezer :Temperature set point (setting mode sign [St]) is –5℉ (-20℃)

Temperature differential set point (setting mode sign [di]) is 8℉ (4℃)

Range of adjustable set point: -22℉~ 8℉(-30℃ ~ -10℃)

* Refrigerator : Temperature set point (setting mode sign [St]) is 36℉ (4℃) in solid door refrigerator

Temperature set point (setting mode sign [St]) is 35℉ (4℃) in glass door refrigerator

Temperature differential set point (setting mode sign [di]) is 8℉ (4℃)

Range of adjustable set point: 25℉~ 50℉ (2℃ ~10℃)

④ Defrost frequency

* Freezer : It is controlled by MICOM and the default defrost frequency is 12 hours.

* Refrigerator : It is controlled by MICOM and the default defrost frequency is 12 hours.

⑤ The light inside the cabinet comes on when the door is opened in Solid Door models

while light is always on in Glass Door models.

The cabinet interior cooling fan has 3 seconds delay when the door is closed.

When COMP. is OFF, EVA. fan repeats ON and OFF according to setting times

If door is opened , EVA. fan OFF and then closed the door, EVA. fan repeats ON and OFF according to setting times

- 41 -

⑥ If door is opened, door open warning sign (LED) will turn on.

If door is opened more than 30 seconds, the sound alarm beeps 3 times, if open more than 60 seconds, the sound alarm beeps 5 times and if open more than 5 minutes, the sound alarm will beep continuously.

⑦ Cabinet interior temperature

* Freezer : If it is higher than 14℉ (-5℃), the panel displays [Hi] and

lower than -50℉ (-40℃), the panel displays [Lo].

* Refrigerator : If it is higher than 68℉ (15℃), the panel displays [Hi] and

lower than 14℉ (-2℃), the panel displays [Lo].
