When people basically talk and blab about air conditioning systems and so, one thing that would right away cross into a person’s mind is cooling a certain room temperature to make that room cold and less hot. Technically, room air conditioning is basically all about controlling and manipulating the room temperature by all means that would then consist of ventilating, heating, and cooling. It is called HVAC in construction terms.
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 air conditioning unit was technically used for not only cooling the air but controlling the humidity as well.
Manufacturing facilities back then had a difficulty with regards to becoming conducive for working and having productive workers due to the intense heat and humidity in their manufacturing sites, which was why these air conditioning units were primarily used by them to increase their productivity as a whole. 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.

A refrigerant, which is found inside an air conditioning unit, is basically responsible for the manipulation of the room temperature, making the air we breathe in cooler and fresher. Some harmful substances found in the refrigerants of early air conditioning units were used to manipulate the temperature in the room to make it cooler, and these substances are namely, methyl chloride and ammonia. They were then eventually replaced by another chemical which was less harmful, called the freon.

Since safety has been something that has been considered important, they made freon 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. 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 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. 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. Another type of refrigerating process technically consists of a refrigerant being pumped on.
