:: Air Compressor Parts ::

Air Conditioners: In an Air Conditioner chemicals are used to cool the temperature of the room. The liquid chemicals are produced from a gas, which again converts to gas form. The chemical transfers the heat from the inside to the outside of the room.

Mainly the Air Conditioner machine has three parts, a compressor, a condenser and an evaporator. The condenser and compressor are in the outside portion of the machine while the evaporator is located inside the room.

In the processor the chemical, which is a low-pressured cooled gas, enters. The processor then squeezes that chemical. It makes the molecules of the chemical come closer together. The closer molecules create high energy and heat. The chemical leaves the compressor as hot and high-pressure gas and enters the condenser. At the backside of the machine we can see a metal fin. It works as a radiator and helps to cool down the heat very quickly. When the chemical leaves the condenser, it becomes very cold. The liquid flows in the evaporator through a small hole.

On the other end the chemical becomes colder and starts to evaporate and becomes gas. As the liquid becomes gas it soaks heat from the surrounding area. The heat of the air is needed to separate molecules of the chemical, which were packed together in the processor. The evaporator also has metal fins to exchange cool temperature with surrounding air. The liquid again leaves the evaporator and begins the same process. A fan connected with the evaporator circulates the cool air into the room.

As many as eighty percent of the new homes being built in the U.S. are built with central air conditioning units installed. Central air just makes sense, as it keeps the indoor temperatures comfortable while filtering and dehumidifying the air. This is particularly nice for people who suffer from allergies or asthma. Fortunately, central air conditioning units can be installed in preexisting homes, too.

When shopping around for central air conditioning units, there are several things to consider. One is the size of the home you will be cooling. Air conditioning units come in different sizes, so it is important to choose the most efficient size for the cooling job you have in mind. If the unit is too large, it won’t dehumidify properly. To determine the right size, consult a contractor. They should have access to a calculation method called “Manual J” that can help you choose a size.

Another important consideration in central air conditioning units is a rating called the SEER rating. These letters stand for Seasonal Energy Efficiency Ratio. New air conditioners are required to have a rating of 13. A unit that was installed over twenty years ago probably has a rating of only 7 or 8. This is because technology has improved the energy efficiency.

By replacing old inefficient air conditioners with new central air conditioning units, you can save a lot of money in cooling costs. It is estimated that increasing the SEER rating from 11.5 to 13 could save you over $500 each year in cooling costs. Also, look for “Scroll(tm) technology” when choosing a compressor for the latest in efficiency.

Another thing to look for in central air conditioning units is the “Energy Star.” This is a certification given to new appliances that use less energy than other new models. Of course, they use a lot less than equivalent units that are a number of years old.

When installing central air conditioning units, the location of the outdoor unit can make a big difference. If it is surrounded by vegetation or is under a deck, the air will not be able to flow freely in and out of it. Not only that, the units can be noisy. Don’t install it near an area where you like to enjoy eating or visiting outdoors, such as a patio or deck.
