※ Location:
① Cluster Radiating Type: It releases heat through the pipes in the front right and left inside of
the refrigerator to release heat to all over the cabinet, which is good for heat radiation and
foamed with rigid urethane,
②
It is installed outside of the refrigerant (old-type).
③
It is gathered in the lower side of the refrigerant, and its heat is radiated forcibly by using the fan.
☞
It releases the residual heat of condensation until it is completely liquefied, and makes the
gas change only its state without changing its temperature.

※ Thickness of the Pipe
① Low Pressure: 0.25” ② High Pressure: 0.19” ③ Capillary Tube: 0.016~0.03” or so
※ Length of the Condenser (300L for a Standard): 86.9’
① AUXILIARY: 16.4’ ② HOT – PIPE: 21.6’ ③ CLUSTER – PIPE: 49.2’

Capillary Tube
1. Roles: It decompresses the liquid refrigerant of room temperature and high pressure to
make the refrigerant of low temperature and pressure and supplies it to the evaporator.
1) It vaporizes the liquid more at low temperature during its evaporation.
2) Though the compressor stops working, the refrigerant does not flow backward to the
condenser but it flows into the evaporator. This makes small the pressure difference
between the high pressure side and the low pressure side, and it makes it easy to operate
the compressor again.
2. Overview
1) Diameter: 0.016”~0.03 or so
2) Length: It is possible to bring it into low temperature and pressure (50
℉ , 71.2lb/ ㎡ ) according to
the resistance of 6.56’ long and thin wall of the copper pipe.
■ Evaporator
1. Roles: It makes food frozen when the low pressure liquid refrigerant from the capillary tube
changes into the low pressure gas refrigerant by absorbing the compartment’s heat.
2. Principle: The liquid refrigerant of low temperature, which flows in from the evaporator,
keeps evaporating until it is completely gasified, and takes the residual heat of evaporation
away from the surrounding.
3. Types
1) Roll – Bond Condenser °ÊDirect Cooling One-Door Type
☞
It rolls and bonds two sheets of aluminum to make a passage for refrigerants.
2) Pin – Pipe Type °ÊIndirect Cooling Two-Door Type
☞ It attaches small-size aluminum sheets on aluminum pipe to achieve good cooling effect.
■ Compressor
1. Roles: It plays the same role as a pump which draws underwater from the earth. It takes
in the gas refrigerant with low temperature and pressure from the evaporator to change it
into the liquid refrigerant with high temperature and pressure in the compressor before
being sent to the condenser.
