A/C Condenser
Air Conditioning Condenser
The air
conditioning condenser cools the gas Freon low enough to turn it into cold
liquid Freon. This is done by running it through a series of fins in the
condenser. These fins are cooled by air coming into the vehicle and thus
cool the Freon.
Many newer vehicles have Verdana serpentine or parallel flow condensers that simply cannot be properly cleaned
and must be replaced
|
The condenser is located in front of the
engines radiator, on most vehicles, where a strong flow of RAM air can
be counted on to draw heat away from the hot high pressure refrigerant.
As with the radiator, air is drawn through the condenser by a fan when
the vehicle is less moving than 30 MPH. |

Condenser Function
Hot, high pressure refrigerant gas enters the condenser at the top, and
liquid refrigerant is delivered from the bottom. The refrigerant
entering the condenser is 100 percent gaseous, as the refrigerant flows
through the condenser the cooler air passing over the tubes and fins
cools the refrigerant below its boiling point, causing it to condense
into a liquid. The latent heat that was absorbed in the evaporator is
then given off to the outside air and the refrigerant is ready for
another cycle through the evaporator. |

R12 Systems
The size and design of the condenser determines the amount of heat that
can be transferred to the outside air. R12 systems utilized a serpentine
tube and fin construction. 5/16 inch diameter tubes were common in R12
condensers. |
|
|
R134a Systems
R134a systems utilize condensers with multiple passages for the
refrigerant to flow through. Some of the passages are only 1.5mm in
diameter. These condensers can be either serpentine or parallel flow in
design. |

Condenser Applications
There are OE replacement and universal condensers. OE style condensers
are listed by model and vehicle year. Universal condensers are listed in
the Illustrated Guide by size, fittings, and type. We provide Multi-Flow
Universal Condensers that can be used in older R12 systems or R12
systems that have been converted to R134a. |
