Your Access To Heating and Air Conditioning.
 

Auto HVAC


Not only do we depend on our cars to get us where we want to go, we also depend on HVAC to get us there without discomfort. We expect the heater to keep us warm when it's cold outside, and the air conditioning system to keep us cool when it's hot.

Air conditioning makes driving much more comfortable in hot weather. Your car's air conditioner cleans and dehumidifies (removes excess moisture), the outside air entering your car. It also has the task of keeping the air at the temperature you select. These are all big jobs. How do our cars keep our "riding environment" the way we like it?

Most people think the air conditioning system's job is to add "cold" air to the interior of the car. Actually, there is no such thing as "cold," just an absence of heat, or less heat than our bodies are comfortable with. The job of the air conditioning system is really to “remove” the heat that makes us uncomfortable, and returns the air to the car's interior in a "un-heated" condition. Air conditioning, or cooling, is really a process of removing heat from an object (like air).

A compressor circulates a liquid refrigerant called Refrigerant-12 (we tend to call it "Freon," a trade name, the way we call copy machines "Xerox" machines). The compressor moves the Refrigerant-12 from an evaporator, through a condenser and expansion valve, right back to the evaporator. The evaporator is right in front of a fan that pulls the hot, humid air out of the car's interior. The refrigerant makes the hot air's moisture condense into drops of water, removing the heat from the air. Once the water is removed, the "cool" air is sent back into the car's interior. Aaaaaah! Much better. Newer cars have R-134 as the refrigerant, but work in the same way as R-12.

We get heat from the heater core, sort of a secondary radiator, which is part of the car's cooling system. We get air conditioning from the car's elaborate air conditioning system.

Sometimes we worry when we catch our car making a water puddle on the ground, but are relieved to discover that it's only water dripping from the air conditioning system's condenser (no color, no smell, and it dries!).

Which Do I Choose?

The gas furnace is always more affordable to use than the electric furnace where gas is readily available. On the downside, burning fuel generates fumes. In well-maintained gas furnaces, the fumes generated are enclosed in the exchanger and then exit the house through an exhaust vent.

The electric furnace has a higher cost than a gas furnace. On the upside, since electric furnaces do not use flames, it does not generate any carbon monoxide. The electric furnace is cleaner and safer than a gas furnace.

The efficiency of gas furnaces are determined by the AFUE or Annual Fuel Utilization Efficiency ratings. The AFUE ratings identifies how efficiently is the fuel being consumed. In most cases, a higher AFUE rating means it takes less fuel to heat your home.

So how do you know the efficiency of your air conditioner? Once way is through an energy efficiency ratio measurement called the SEER. This SEER is used to rate all air conditioners on their efficient use of energy in order to set a standard of environmentally friendly machines. The term SEER stands for seasonal energy efficiency ratio. Generally the higher the number of SEER the air conditioner is given, the more energy efficient it is.

Did you know that one sixth of all the electricity generated in the United States is used to air condition buildings? With that thought in mind the U.S. Department of Energy is raising the minimum energy efficiency rating for air conditioners as of January 23 2006. Whether it is to reduce consumers’ energy bills or reduce pollution, higher energy efficiency ratings on air conditioners can only be beneficial to everyone involved.

As environmental concerns continually grow the SEER on air conditioners has changed. In 1992 the SEER minimum standard for air conditioners was 10 and by 2006 it was rumored that it would be changed to a minimum of 13 and voila, that will be the new standard when this new law is passed in January. A change from a 10 rating to a 13 rating in SEER roughly translates into a 30 percent improvement in efficiency of that particular air conditioner.
