The History Of Air Conditioning

The History Of Air Conditioning - Air conditioning systems prevail throughout the world, and the latest developments offer simple convenience with minimum technical issues. Fascinatingly, the first air conditioning unit of the 20th century included a "Refrigerant system" that contained harmful gasses such as gas, ammonia and methyl chloride. The chlorofluorocarbon gasses as we use today came into existence in the year 1928 with the advancements made by Thomas Midgley. Nevertheless, the credit for creating an electrical cooling system or air conditioning is attributed to Willis Carrier and his creation controlled both temperature and humidity effectively. Because their creation the a/c unit were included with technology and their size is reduced phenomenally. Also, there developed different types of air conditioners that serve for specific functions.

Kinds of Air conditioners

1. Window a/c - The most typical type of Air Conditioning utilized across the world, which is suitable for little to medium sized rooms. The parts of the window A/C such as condenser, coil, growth valve, compressor, cooling coil, evaporator, and so on are placed in a single unit so that it can be fitted perfectly into the wall of a room. This is extremely inexpensive when compared to other types of AC system, and the installation procedure is likewise easy.

2. Split air conditioning system - These are more popular with larger spaces and small office. The Air Conditioning consists of primarily of two parts namely, the indoor system and the outside unit. The indoor unit can fit inside the room with ease, and it includes components like expansion valve, condenser, and cooling coil. The external or outdoor unit is put beyond your house, and it has the compressor. The best benefit of Split Air Conditioner is that there needs no specific treatment or window sills to install it and it can be placed on any wall.

3. The packaged air conditioning system - The system is used to cool several spaces, and it can operate in two ways. In the most popular method, all the elements are put in a single package, and the cool breeze developed in the system is sent through the duct. The second way operates in a comparable style, but the cool air is provided to each with the aid of specific systems which contain cooling coil and the growth valve. The installation process is made complex to this mechanism, and if any problem occurs, it takes the attention of professionals.

4. Central air - Most ideal for large buildings such as malls, hotels, theaters, and so on the central air conditioning gets rid of the pain of installing specific systems throughout these great constructions. The system consists of a large compressor able to produce tons of cool air continuously across all the rooms. The setup process needs specialists who will comprehend the facilities of the structure and strategy to install the central air conditioning appropriately.

Apart from these, there are numerous small variations of air conditioning system that work basically with the same practical elements as given up the above four major types.

How does an ac system work?

The basic concept behind the working of an air conditioner is the conversion of gas to liquid and liquid with the assistance of chemicals. These chemicals take the heat off the within room environment, and the other components assist to send out cool air into space. The air conditioning system has three significant elements - compressor, evaporator, and condenser - that work all at once to maintain the desired temperature.

As the working fluid goes into the compressor, it is securely squeezed so that the particles achieve greater temperature and energy. The hot fluid is sent out to the condenser so that the temperature level is lowered and all the heat is sent out. The cool liquid is sent out to the evaporator through a tiny hole so that the pressure of the liquid drops substantially. As an outcome, the liquid gets transformed into a gas it is provided to the room with the assistance of a fan. The hot air builds up on top and is gotten by a vent. The process repeats itself over and over once again so that the temperature inside the room stays undamaged.


The working principle of an ac system is very easy, but the process of attaining the outcomes through various parts is extremely complicated and needs consistent monitoring from the HVAC professionals. With a correct upkeep and looking after small repairs, an air conditioner can last a life time without troubling the user.
