A basic preview as to what does air conditioning mean
Also referred to as an AC or even an aircon, this is a process that involves changing the temperature and humidity of air into conditions that would be suitable for the inhabitants. It is a technological process. It involves cooling, heating, ventilating and as well as disinfecting a particular place.
What does the process involve?
In today’s world, having an AC during the summers has become a kind of a mandatory thing. It has become a very useful home appliance over the years. An A/C helps change not only the temperature of a given place but also takes away the humidity. These are used to not only to cool a place but also heats depending upon the requirement.
The cooling process comprises of a refrigeration cycle. However, it may also use the process of evaporation so as to comfortably cool a building or even a vehicle. There is yet another process and it is known as free cooling. This method employs pumps so as to circulate a coolant from a source that is cold. This cold source becomes a temporary heat sink so as to remove the energy from the cool place.
Various types of ACs
Normally, room ACs can be of two types: there are the unitary systems and the other is known as the packaged terminal (PTAC) systems.
- The unitary system has interior controls. They are usually placed in a window or even a wall opening. According to this process, heat is sucked out of the room to the outside. In case of a single room, there is a requirement for only one unit. However, if it concerns a huge building, several units may be required which will allow different rooms to be cooled separately.
- On the other hand, the PTAC system has two separate units. Used normally in hotels, the two units are: the evaporative unit situated inside and the condensing unit placed outside. Also known as wall- split AC systems; a tube passes through the wall to connect the two units.
- Split systems: It is divided into two types: central as well as mini split. In both these systems, the heat exchanger and fan of the interior is separated from the same of the exterior.
- Ductless systems: Quite similar to that of the PTAC ACs, they are also designed so as to cool a single room. But these ductless ACs are more flexible. They have become more powerful than before, and therefore, cool bigger spaces. However, they are quite costly.
- Central AC systems: Takes care of a big space which may include a big house.
- Evaporative coolers: Used to cool in places like deserts. They are very popular in such areas, they suck the outside air and the temperature is reduced.
- Portable ACs: These can be taken from one place to another. They are either evaporative or refrigerative.
- Heat Pumps: These are another type of aircons. Here, the refrigeration process is reversed. Hence, it produces heat inside a space, rather than cooling it.
Hence, to conclude,
It can be said that for some households, air conditioners may be a luxury, but with the growing amount of global warming and heat, these are gradually becoming necessities. They take out the humidity of a particular place and turn the space cool. These are healthy as well as they don’t let harmful pesticides grow.
