Refrigeration: after the refrigerant enters
the pipeline of the refrigeration system, it
is pressurized by the compressor into
refrigerant gas of high-temperature and
high-pressure, and then into liquid state
(actually a vapor-liquid mixture) after being
cooled through the condenser. The liquid
refrigerant is throttled by an expansion valve
in front of the evaporation tank, enters the
evaporation tank in the form of fog, absorbs
the surface temperature of the evaporator core
to make it cool. Heat exchange occurs when the
hot air sucked by the air blower passes through
the evaporation tank, it turns into cold air
and enters the cabin from the air outlet.
Heating: A heater box is arranged in the
evaporation tank, which is also referred to as
a heat exchanger and is directly connected with
the engine water tank via a water pipe; the cold
air sucked by the blower turns into hot air when
passing through the surface of the heat
exchanger by absorbing heat, and enters the
cab.
