Choosing A Cooling Option: Trane Air Conditioners

Among the many choices of air conditioning units avail, Trane air conditioners have a solid reputation. Most conditioning units are one of two types. They either regulate heat through evaporation or through refrigeration. The kind of unit that is best for any local depends on a number of factors, including humidity level.

Arid areas, where the air is very dry, lend themselves to the so-called swamp or desert cooling units. These units operate by evaporation and require water. The water is absorbed by fabric, through which hot, dry air is drawn by a fan. This combination of heat and dryness cause some of the water to evaporate. As a result of this process, some of the heat is absorbed in the water vapor. The resultant air feels cooler and more humid.

Like everything else, these units do have some negative effects as well. The moisture in the air can aid in the growth of black mold if the air is not properly vented. Creating this circulation is relatively easy, however. All that is needed is to have a window open, even if the window is only part way open. Another problem area is wooden furniture. Moisture causes wood to swell. Over time this expansion and subsequent shrinking of wood can cause it to crack. Yet another disadvantage is that when relative humidity is high, these units do not work well.

On the other hand, units operating through refrigeration are usually called central air or air con, depending on the country. They work through a heat transfer process. The air that is being conditioned passes around liquid filled coils. The liquid in the coils is much colder than the surrounding air. Heat always flows from high temperature to low temperature. Therefore, heat from the air flows into the cold evaporation coils. The liquid within evaporates and is circulated to an outside condenser unit. The refrigerant is forced to condense to a liquid which draws out the heat. The heat is then vented to the outside air. The refrigerant is cycled back to the evaporator unit and the cycle begins again.

A pair of scientists from the United States explored this type of refrigeration in the middle of the seventeen hundreds. These men were John Hadley and Benjamin Franklin. Hadley taught chemistry in college. They used a bulb thermometer to conduct a bunch of experiments. One result they obtained was that of lowering the thermometer reading by thirty two degrees Celsius. A half century later, Michael Farady, a British inventor, conducted his own experiments, using differing liquids as the coolant.

These findings led a doctor from Florida, named John Gorrie, to build a machine to create ice. He would then blow air over the ice in an effort to make his patients more comfortable. His device was so successful that he planed on producing many such units for the public. Unfortunately, however, his source of funding died, leaving his plans in ruins.

Later still, Willis Carrier from New York began building functional units in the early twentieth century. His units were designed to cool textile plants. Word of his devices spread and people began desiring units for their homes.

Through the passage of time a number of firms have joined the ranks of manufactures of these units. Trane air conditioners are well thought of with a good reputation.
