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 in ZICA, as in many other vehicles 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.
