Expansion valve<br />

The expansion valve restricts and<br />

controls refrigerant flow to the<br />

evaporator thus lowering refrigerant<br />

temperature and pressure.<br />

Note:<br />

The R-134a expansion valve may be<br />

identified as such with a label.<br />

Evaporator<br />

Liquid refrigerant entering the<br />

evaporator absorbs heat from air<br />

passing through the evaporator fins<br />

and cools the air. As the refrigerant<br />

absorbs heat it turns to vapor and<br />

then is suctioned by the<br />

compressor.<br />
