The Advantages Of Air Conditioning When people talk about air conditioning, the first thing that would basically come into their minds is the fact that air conditioning makes rooms cooler and less hot. 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. Later in the 1900s, the first electrically-run air conditioning unit was installed and used at a certain printing plant. The air conditioning unit was technically used for not only cooling the air but controlling the humidity as well. 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. It was only in the late 1950s when private civilians started using air conditioning units in their homes and cars as well so as to become more convenient and comfortable.

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.

Freon is considered completely safe for human beings. But sadly, freon can cause so much harm and danger for 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. Apparently, a variety of air conditioning units nowadays still use the same type of gas to control the temperature causing heat and humidity in the air. It has been said and believed that environmentalists and nature lovers alike will have to wait until a certain time that these gases will no longer be used and replaced with another more nature-friendly ones. Air conditioning units basically have a variety of refrigeration cycles that they all go through to make the temperature better and have lesser humidity. The first type of refrigeration process is through the use of a heat pump that is responsible for shooing out hot air that causes heat and humidity, letting the compressor in the air conditioning unit blow in cooler air to lessen the hotness in the room. Another type of refrigerating process technically consists of a refrigerant being pumped on.
