Air Conditioning- The History Of Air Conditioning

Air Conditioning- The History Of Air Conditioning


It is so easy in the modern world to take air conditioning for granted. With the advances in technology is now virtually unheard of for air conditioning not to be used in any group building. everywhere where potential customers are being courted for their business, it would be very unwise to leave them in a state of extreme discomfort, due to the failure to keep the building's facilities in line with the competition. In government buildings, failure to sound a comfortable environment would reflect very badly on those who are responsible for the upkeep of the construction and, by association, the agency that utilises it.

Air Conditioning- The History Of Air Conditioning

It has not always been this way. Air conditioning was, in days gone by, a maintain of the rich. Even as far back as ancient Egypt and ancient Persia, some form of primitive air conditioning theory was in use in the palaces of the wealthy aristocrats. These early air conditioning units were based on using water, sometimes in conjunction with cold air, to cool the brickwork of the buildings. This kind of use for a valuable reserved supply such as water, especially in the desert, was extravagant in the extreme and obviously only ready to the ruling classes.

The major breakthrough in the history of air conditioning came from the noted British creator and scientist Michael Faraday. Faraday's study proved that it was potential to compress and melt ammonia and then use the liquefied ammonia to cool the air by having it evaporate. It was nearly a century after Faraday, however, that the first serious application of this kind of technology was seen. This was not used to control the temperature of rooms, but to regulate temperature and humidity in industrial printing processes. Air conditioning technology evolved from this, to be applied in the regulation of temperature in rooms and buildings.

The term "air conditioning" did not nothing else but exist until 1906. Stuart W. Cramer, a textile mill owner, first used it. Cramer had been experimenting with ways to ameliorate the effects of the dry air created by his industrial processes. The patent he filed had used the term in conjunction with "water conditioning", which had already become a familiar and often-used term in the textile industry. The new developments that Cramer instigated had a dramatic ensue on the air capability within his factory and, as a direct consequence, on productivity.

In recent years, the prestige of air conditioning technology has taken a severe blow. The gases used in the early days of air conditioning were very similar to the ammonia first used by Michael Faraday. These very toxic chemicals were potentially lethal should they have escaped into the atmosphere. It was obviously valuable to try to furnish a far safer alternative. The types of gas advanced in the 1920s - chlorofluorocarbons and hydro fluorocarbons - were far safer to human beings and were used in many different types of air conditioning theory in the twentieth century. Towards the end of the century it emerged that these gases were harmful to the earth's ozone layer and again the need has arisen for alternatives to be developed. Amid an ever-greater awareness of environmental impact new non-harmful gases have been advanced and many of the old ones have been phased out. The time to come of air conditioning now looks promising, with ozone harming gases eliminated and a commitment to enhancing the vigor efficiency of air conditioning systems.

Air Conditioners Changing to R410a Refrigerant

Air Conditioners Changing to R410a Refrigerant


With the world craze to "go green" we are finding a new ideas being implemented in the way we use air conditioning.  The existing ideas which many population refer to as Freon is truly what is termed R-22. The R-22 refrigerant is being replaced by the R410a refrigerant which is a much more environment friendly and vigor conserving system.  This overhaul is slated for 2010 and will replace the R-22 with the R410a wholly because they work on two opposite pressure systems.

The copper lines that the R-22 use will need to be changed out because it uses mineral oils that break down into damaging carbons that are speculated to be causing the global warming crisis the governments of the world seem to be so worried about. R-410a will use synthetic oil that will be able to preserve at much higher temperatures than that of the old.

The old piping will have mineral oil deposits throughout the piping and this is what the new ideas is aimed at improving and replacing. If the piping is not replaced it will wreak havoc with the new ideas because it will not be able to take the pressure of the R410a and will found deposits on the compressor walls and damage the metering device.

The implementation of this new ideas will need a fresh start because if you were to integrate the two it will cause the very same problems that the R-22 is said to be causing.  The old ideas could have moisture retained inside the piping and this does not go well with the functions of the new R-410a.

If you are told by an installer or sales man of the new refrigerant that you can use your existing piping because they are going to blast it out or flush them out make sure you tell them you know more than they do and you want to have the piping wholly replaced when they install the new heating and air system.

Whether you believe in global warming or not is irrelevant because we are going to see a change in all the carbon systems that are currently operating across the planet. This being the case you might as well do your homework and get a firm understanding of what these changes are going to be so you know what you need to do to and how to abide by the inception of new equipment.
