10.1.5.4. CONDENSER AND RECEIVER DRIER
CONDENSER (PETROL)
CONDENSER (DIESEL)
The condenser is a heat exchanger used to cool the
hot vapourised refrigerant. Also the refrigerant
changes its state from vapour to liquid. The conden-
ser is placed in front of the radiator behind the
radiator is the fan used to draw in ambient air.
CONDENSER SEALING DUCTS
Sealings are used to guide the flow of the air to the
condenser and also to avoid the hot air recirculating
from the engine compartment to the condenser.
RECEIVER DRIER (R.D)
The receiver drier is integrated into the Condenser
and has three main functions.
i) It absorbs the moisture in the refrigerant.
ii) It allows only liquid (
high pressure liquid)
to pass
through to the TXV.
iii) It keeps a reserve of refrigerant to accommodate
fluctuating refrigerant requirements.
