Las Vegas, NV (Vocus) August 24, 2010

Beginning this week, Sun Auto Service, a leading automotive repair company will be providing monthly advice via an online e-newsletter for those interested in learning more about their vehicle. The first article is about auto air-conditioning. An excerpt is provided below:

In the southwest, just about every new vehicle is sold with air conditioning. It’s a must during the 110 plus degree summer temperatures. Las Vegans don’t take this modern-day luxury for granted. A press of a button and turn of the dial renders that blast of cold air flowing from the vehicle's air vents.

Air conditioning is the process by which air is cooled and dehumidified. The air-conditioning in one's car, home and office all work similarly. Basically, air conditioning systems operate on the principles of evaporation and condensation.

The principles of evaporation and condensation are utilized in your car’s A/C system by a series of components that are connected by tubing and hoses. There are six basic components: the compressor, condenser, receiver-drier, thermostatic expansion valve, the evaporator and the refrigerant. Refrigerant is a stable substance that can be condensed and under pressure gets cold.

1. The compressor is the power unit of the A/C system. A drive belt connected to the engine’s crankshaft powers it. When the A/C system is turned on, the compressor pumps refrigerant vapor under low pressure to the condenser.
2. The condenser is a device used to change the high-pressure refrigerant vapor to a liquid. As the car moves, air flowing through the condenser removes heat from the refrigerant, changing it to a liquid state.
3. Refrigerant moves to the receiver-drier. It removes moisture from the refrigerant.
4. As the compressor continues to pump, liquid refrigerant under high pressure is circulated from the receiver-drier to the thermostatic expansion valve. The valve controls the low side pressure and regulates the temperature.
5. The evaporator is very similar to the condenser. As the cold low-pressure refrigerant is released into the evaporator, cool air will be available for the occupants of the vehicle. A blower fan blows air across the cold evaporator and inside the passenger compartment that helps to distribute the cooler air.
6. Finally, the heat-laden, low-pressure refrigerant vapor is then drawn into the compressor to start another refrigeration cycle.

E-newsletters will be available on a monthly basis and shall cover topics such as Brakes, Diagnostics, Transmissions and more. For more timely tips on everything automotive readers may go to http://www.SunAutoServiceUSA.com.
