●

A freezer works by drawing the heat out of the freezer
compartment.
●

●

To start the process, the refrigerant-in gas form-goes
into the compressor where the compression process
causes it to get very hot.
The temperature of the mist is around -27 degrees at
this point, and it takes the heat from the freezer
compartment with it.

Freezers
To get an idea of
how it works,
picture a river as
it winds through
the mountains
and countryside
en route to the
ocean.

Refrigerator
Refrigerant
flows and
transforms
from liquid to
gas and back
in a similar
way.

●

Some of the most commonly used refrigerants are
HFCs.Other refrigerants, such as CFCs and HCFCs are
highly regulated and banned from use in many products in
the United States.
The first freezer component
it enters is the compressor
(usually found in the lower
back of the freezer). The
compressor squeezes the
vapor's particles, which heats
it up and converts it into a
high-pressure state.


The Basic Components of a Freezer
The components of a freezer are as follows:
●
●
●
●
●

A compressor
A condenser
An evaporator
A capillary tube
A thermostat


1) Compressor
The compression process makes
this low pressure refrigerant a
hot, high pressure gas.

2) Condenser
The fins conduct this heat away from
the coils. The capillary tube regulates
the pressure of the refrigerant as it
enters the coils.


3) Evaporator
A cold, low pressure gas is then
produced when the liquid
refrigerant expands, boils, and
evaporates into the evaporator
coils.

4) Thermostat
The thermostat tells the
compressor when to be on by
supplying electricity to the
compressor.

Important Points Of Freezers
●

●

●

●

The refrigerant begins the cooling process as a vapor under low
pressure.
The compressor squeezes the vapor's particles, which heats it up and
converts it into a high-pressure state.
As the vapor travels through the condenser coils, it loses the heat but
retains its high pressure.
Vapor compression isn't the only way to create a super-cold food
storage environment.


Freezers temperature
●

Bacteria are usually the cause of food decay, but they can't
grow as well or at all in freezing temperatures, which are at
32 degrees Fahrenheit (0 degrees Celsius) or lower.
●

Food spoils more slowly if you lower the liquid inside
it - the water molecules -- to freezing temperatures.


Types of Freezers
There are two principal types of freezer :
1) Chest Freezers
(sometimes called dive-in)
2) Upright Freezers
(sometimes called reach-in)


Chest Freezers
Chest freezer is that it is difficult
to get to food stored at the bottom
of the freezer.
Always buy a chest freezer
which has baskets that hang from
the top.
Most units are manual defrost
High energy efficiency
Lift-out drawers for easier
organization.
Range in size from 5.0 cu. ft. to
25.0 cu. ft.

Upright Freezers
Upright freezers open like a
refrigerator and include a variety
of shelves and storage drawers.
Units vary in size and offer a
wide range of capacities.
Take up less floor space for
easier placement.
Lighted interior enables you to
see and organize food more
easily.
Range in size from 5.0 cu. ft.
to 21.0 cu. ft.

Buying a New Freezer


●

Depending on what your budget and needs are, today's
freezers have all kinds of technologically advanced bells
and whistles.
●

In which features you select, your new unit could cost
anywhere from $500 to $4,000 or even more.


Features you might look for when
1) Digital external temperature regulator:
considering your next freezer purchase:
It keeps you from having to reach into the
back of a cold freezer to twist an icy knob
that's frozen in place.

2) Automatic ice-makers:
Icemakers in the door that you access
externally will make your freezer last
longer because that's one fewer time you
don't have to reach inside and risk wear to
the rubber seal.

3) Cold water filter:
You get fresh, chilled water dispensed from the
freezer door.

4) Cooling zone compartment:
Available in some freezer combos is a
hidden tube routing super-cold freezer air to
a space in the fridge designed for storing
items that perish quickly, such as milk.

5) Automatic defrost:
We talked about earlier, this should prolong
the life of your freezer so you won't have to
go freezer shopping again anytime soon.
