evaporator

EVAPORATOR
A refrigerant in liquid form will absorb heat when
it evaporates and it is this conditional change
that produces cooling in a refrigerating process. If
a refrigerant at the same temperature as ambient
is allowed to expand through a hose with an outlet
to atmospheric pressure, heat will be taken up
from the surrounding air and evaporation will occur
at a temperature corresponding to atmospheric
pressure.
If in a certain situation pressure on the outlet side
(atmospheric pressure) is changed, a different
temperature will be obtained since this is analogous
to the original temperature - it is pressuredependent.
The component where this occurs is the evaporator,
whose job it is to remove heat from the surroundings,
i.e. to produce refrigeration.
