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 alow 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		COMPRSSOR

EVAPORATOR

THE BASE REFIGERATION 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 alow pressure gas at the evaporator outlet.

The compressor pumps this gas from the evaporator, increases its pressure, and discharges the high pressuredtemperature gas to the conenser.

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

The capillary tube prevents high pressuredtemperature gas 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 regrigerator inner-cabinet is reached, the thermostat (temperature controller) will break the electrical circuit to the compressor motor and stop the compressor.

-6 -

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 BASF1/BASF2/BASF3/BASR1/BASR2 BASR3/BAGR72 is like below.

1.OPERATION FOR BASF1, BASF2, BASF3 MODELS

1)BASIC OPERATION

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 (BASF1, BASF2 models) ] [ The unit should be plugged into a 115V/208~230V, 60Hz (BASF3 model) ]

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

If cabinet interior temperature is higher than 14 (BASF1, BASF2, BASF3 models), compressor

will run without delay, and lower than 14 (BASF1, BASF2, BASF3 models), compressor will run after 3 minutes.

The default OPERATING TEMPERATURE SETTING

BASF1, BASF2, BASF3 : Temperature set point (setting mode sign [st]) is –9

Temperature differential set point (setting mode sign [di]) is 10 . (Operating Temperature : -14 ~ -4 )

Range of adjustable set point: -22 ~ 8

Dfrost frequency is controlled by MICOM and the default defrost frequency is 6 hours.

The light inside the cabinet comes on when the door is opened.

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

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

If door is opened more than 30 seconds, the sound alarm beeps 3times,

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.

If cabinet interior temperature is higher than 14 (BASF1, BASF2, BASF3), the panel displays [Hi] and lower than -50 (BASF1, BASF2, BASF3), the panel displays [Lo].
