The Advantages Of Air Conditioning Basically when one hears about air conditioning, it always boils down to being all about cooling down a certain room temperature, making it cold for everyone inside that certain room. Air conditioning is not only about making a certain room cold and less hot, but it is technically also all about manipulating the temperature of a room in a wider sense, also covering its ventilation and heat. In terms of construction, is is basically called HVAC. This air conditioning system was basically used since the 1900s, in a specific stock exchange building initially. After that, the very first electrically-run air conditioning unit was then made, installed, and used at a certain printing plant in the late 1900s. The unit was not only responsible of cooling the air but also on controlling the humidity. Since a lot of manufacturing facilities back then were suffering from too much heat and humidity, making their workers less productive, these air conditioning units were solutions as to solve the problem on these manufacturing sites. Since the 1950s, private civilians have already used these air conditioning units in their homes and automobiles as well so as to have more convenience with the way they lived.

An air conditioning unit basically has this system called a refrigerant which allows the temperature of a certain room less hotter. Back then when air conditioning units were not much developed, they used harmful substances to manipulate the temperature in the room, using ammonia and methyl chloride as their refrigerants. These harmful chemicals were then eventually replaced by a new one called a freon, that still has the ability to make a room cooler.

Human being can basically trust the fact that freon does not have the ability to harm them in any way possible. Moreover, freon is and can be harmful to the environment. If one releases freon into the environment, there is this certain chlorofluorocarbon gas that is emitted to the ozone layer, making it thinner, thus causing more heat from the sun to the surface of the earth. A lot of air conditioning units still use the same type of gas even up until today, to help manipulate the temperature of the air, causing it to become cooler and more refreshing. It has been believed that environmentalists and some nature lovers will have to wait until a certain amount of time before innovators will have to replaced these harmful gases and replace them with safer, better, earth-friendlier ones. There are a number of refrigeration cycles that an air conditioning unit will have to go through to manipulate the temperature of the air. A heat pump is used for the first type of refrigeration process that can basically drive out hot and humid air from the room and make it to a point to create a cooler air that comes out from the compressor in the air conditioning unit. The second type of refrigeration process just basically involves the pumping of a refrigerant.
