| Coolant |
A
chemical with ideal physical properties such
as pressure and emperature of phase transition
suitable for refrigerator's working principle. |
| Freon gas |
Most commonly
used coolant. Freon gas for refrigerator is
R12(CFC) and molecular formula is CCI2F2. |
| New Coolant |
R134a(CFC
FREE), molecular formula: CH2FCF3. |
| Insulation |
This is
to prevent thermal conduction between cold
inner part of refrigerator and warm outer
casing of refrigerator. |
Insulating
material |
Material
used for refrigerator insulation. Polyurethane
foam is most commonly used. |
| Foaming |
This is
to heat up liquid polyurethane so that it
rise to solid insulating material. |
| Foaming
agent |
A chemical
which helps liquid polyurethane to rise during
foaming. |
| DEFROST |
This is
to melt frost and ice on evaporator of a refrigerator. |
| Natural
defrost |
Defrosts
the evaporator at room temperature by turning
off the refrigerator. |
| Forced defrost |
Defrosts
the evaporator using equipments such as a
heater. |
| Defrost
water |
Water produced
during defrost. |
| Defrost
timer |
An automatic
defrosting timer that starts defrosting at
a regular interval. |
| Thermo-timer |
An automatic
defrosting timer that starts defrosting at
a regular interval. |
| Thermostat |
Thermostat
senses internal temperature of a refrigerator
using FEELER and controls a compressor according
to a set temperature. |
| Damper |
In an indirect
cooling type refrigerator, a damper controls
the cold air flow to refrigerating compartment
and fresh compartment according to a set temperature. |
| Cold air
inlet |
This is
a cold air duct to facilitate the circulation
of cold air inside a refrigerator into evaporator. |
| Cold air |
As coolant
evaporates, it absorbs surrounding heat, thus
generating cold air. |
| Leakage |
Coolant
leaks out of the circuit into atmosphere. |
| Coolant
inclusion |
Inserting
coolant in a compressor and welding for it
not to leak. |
| Ice making |
To freeze
water to ice |
| TRAY DRIP |
A tray where
defrost water is collected. It is located
where water can be vaporized by the heat of
compressor and drain condenser. |
| Drain condenser |
An equipment
located under a tray drip. It evaporates defrost
water using a part of evaporator. |
| Gasket |
A packing
material which prevents leakage of cold air
inside a refrigerator from through a door
crack. |
High speed
refrigeration |
This function
is too shorten freezing time by maintaining
continuous operation for a certain period
time and increasing cooling fan speed. |
Multi-purpose
compartment |
You can
store a variety of food in here. |
| DEW |
Dew is formed
on the surface of a refrigerator when cold
air from the inside collides with warm air
from the outside. |
