2. Receiver
Function
It cools and liquefies the high-pressure and
q
high-temperature misty refrigerant from the
compressor.
The receiver holds high-pressure, high-tem-
q
perature liquid refrigerant.It is capable of com-
pletely liquefying the refrigerant even when
bubbles are contained in the refrigerant due to
the condenser condition in heat dissipation.
It eliminates foreign substances in the circula-
q
tion circuit and water content in the refrigerant
by use of the built-in filter and desiccating
agent.
a If the fin crushes or is clogged with dusts, heat
exchange efficiency is degraded and complete
liquefaction of refrigerant becomes unavail-
able. As the result, pressure in the refrigerant
circulation circuit will be increased, applying
extra load to the engine or degrading the cool-
ing effect. Thus, care must be used in its han-
dling and daily inspection.
