Refrigeration is a process in
which work is done to move
heat from one location to
another. The work of heat
transport is traditionally driven
by mechanical work, but can
also be driven by heat,
magnetism, electricity, laser, or
other means.
-Evaporator : The evaporator is
where the heat is removed from
your house , business or
refrigeration box.
*
Two different pressures exist in the
refrigeration cycle. The evaporator or low
pressure, in the "low side" and the
condenser, or high pressure, in the "high
side".
These pressure areas are divided by the
other two components. On one end, is
the metering device which controls the
refrigerant flow, and on the other end, is
the compressor.
*
-Compressor : The compressor
is the heart of the system.
It compresses the low pressure
refrigerant vapor from the
evaporator and compresses it into
a high pressure vapor.
-Condenser:The hot vapor enters
the condenser and changes to
liquid.
-The Metering Device: A very
common type of metering device
is called a TX Valve (Thermostatic
Expansion Valve). This valve has
the capability of controlling the
refrigerant flow(lowering pressure)

has many applications, including, but
not limited to: household refrigerators,
industrial freezers, cryogenics, and air
conditioning. Heat pumps may use the
heat output of the refrigeration process,
and also may be designed to be
reversible, but are otherwise similar to
refrigeration units.
