Air Conditioning

By • Category: Services


Your air-conditioning is a complex system, responsible for keeping you cool and comfortable.

The system works much like a refrigerator. A compressor pumps liquid refrigerant (often called freon) through the evaporator located under the dashboard. Here, the liquid refrigerant changes to a vapor as it absorbs heat in the passenger compartment. This hot vapor is then circulated to the condenser, where it changes back into a liquid as it releases heat through the front grille.

This process is continual, so the refrigerant is constantly cycling from liquid to vapor and back to liquid again. In this way, heat is carried away from the vehicles interior leaving you with a cooler driving environment.

AIR CONDITIONING BASICS:
Your air-conditioning system consists of four major parts, which provide cooling for the passenger compartment. The industry generally has two different system designs. These designs are identified as expansion valve or orifice tube type.

* The compressor, mounted on the engine, is the pump that circulates the refrigerant through the system, transferring the heat from the passenger compartment to the outside air. The compressor is the most important and expensive component of the air conditioning system.
* The condenser transfers heat removed from the passenger compartment to the outside air. It is located in front of the radiator, just behind the front grille of the vehicle.
* The evaporator, located near the dash board or firewall, transfers the passenger compartment heat to the refrigerant, so it can be sent to the condenser, removing heat cools the passenger compartment.
* The dryer absorbs any excess moisture from the refrigerant.
* Flexible hoses transfer the refrigerant both to and from the engine-mounted compressor and to the other system parts that are mounted on the vehicle body. The flexible hoses can be a major source of refrigerant leakage. The system also has many connections that require rubber seals that should be frequently checked for leaks.

REPAIRING YOUR AIR CONDITIONING SYSTEM
Before having your airconditioning repaired, it is important for you to communicate your complaints clearly, and to tell your Rapide technician if anyone else has recently worked on the system. Then, the technician will inspect your system, following these steps:

* First, your technician will start the engine and check the blower and vent operation.
* If all controls are working properly, the airconditioning will be set to maximum air with the fan on high, to determine the temperature of air through existing vents.
* The technician will run a performance test on the high and low pressure portions of the system.
* Next, the technician will perform a complete visual inspection of the system. This includes checking the condition of belts and hoses, making sure service port caps are screwed into place properly, and looking for oil stains or caked-on dirt along all exposed parts and hoses.
* The technician will leak test the entire system.
* Finally, the technician will check the condenser and radiator to make sure the leaves, debris, or dead insects aren’t reducing air flow over the condenser coils.
