The above figure shows the circulation diagram of a
refrigerant which passes through the 5 main compo-
nents of the air-conditioning system.
The refrigerant shall be flowed into the compressor as
the compressed cold low-pressure steam and then
ejected as the hot high-pressure steam and get into
the condenser.
When the hot high-pressure steam passes through
the condenser core, this discharges the heat to the
colder air outside and passes the pin by engine cool-
ing fan and to be drawn.
By discharging the heat to the air outside, the steam
shall be compressed as a fluid and moved to the re-
ceiver drier where this is stored until the vaporizer shall
be discharged by the temperature extension valve as a
state of high pressure.
When the fluid refrigerant passes through the mea-
surement hole of extension valve, the refrigerant is
changed from high pressure fluid to the low tempera-
ture and low pressure injection fluid.
Such low pressure, low temperature and injected fluid
enters into the coil of the vaporizer to absorb the heat
from the hot air of the cabin and blow it to the coil and
the pin by blower motor. The refrigerant is changed
from the cold low pressure injected fluid to the hot low
pressure steam and moved from the exit of the vapor-
izer to the absorption side (low pressure) and then
repeats the circulation.
When the heat loss occurs, the moisture (humidity) of
the air in the cabin shall be compressed at the outside
of vaporizer and flowed out as a water through the drain-
age hose attached to the drainage fan of vaporizer,
which result in decreasing the humidity of the cabin.
