The full form or meaning of the acronym HVAC is Heating, Ventilation and Air Conditioning which is related to a type of comfort technology. Heating, Ventilation and Air Conditioning is used as indoor and vehicular environment technology for comfort.
So the Heating, Ventilation and Air Conditioning technology provide a comfortable environment indoors and even vehicular.
The purpose of this Heating, Ventilation and Air Conditioning is to give acceptable indoor air quality that is needed along with thermal comfort.
The system of the Heating, Ventilation and Air Conditioning is designed and created as a mechanical engineering sub-discipline as it combines the technology as the inbuilt product so it indicates the mechanical engineering sector.
About HVAC (What is HVAC?)
The technology of Heating, Ventilation and Air Conditioning is based on thermodynamics, heat transfer, fluid mechanics etc. principles.
in simple words, HVAC is a device that works as a heater, exhaust and AC.
This means this device will cool you in summer, in cold you can use it to get heat, and in any other situation you can also use it as an exhaust fan
In some other cases, the word Refrigeration can also be added in the Heating, Ventilation and Air Conditioning term so that makes it HVAC&R or HVACR.
In some other cases the word ventilation can be removed from the Heating, Ventilation and Air Conditioning term which makes it HACR that refers to Heating, Air Conditioning and Refrigeration.
The building process of properties especially residential structures require the system of Heating, Ventilation and Air Conditioning a lot in the present so it plays a crucial role in the process building of single-family homes, hotels, senior living facilities, apartment buildings, medium and large industrial buildings, office buildings, hospitals etc.
apart from residential buildings the Heating, Ventilation and Air Conditioning technology is used in vehicles as well such as trains, aeroplanes, cars, submarines, ships, marine environments etc.
in healthy and safe marine buildings all the conditions are strictly regulated for the appropriate temperature and humidity. This is done in the Heating, Ventilation and Air Conditioning through fresh outdoor air.
In the system of Heating, Ventilation and Air Conditioning technology the ventilation process is used to remove the unpleasant smells, excessive moisture so it can provide outdoor air which is used to keep the inside interior building air circulating along with preventing unproductivity of the inside air.
There are many inventors of Heating, Ventilation and Air Conditioning technology so the system is built on the inventions and discoveries of these inventors.
The inventors of this Heating, Ventilation and Air Conditioning system are James Joule, Michael Faraday, Willis Carrier, Nikolay Lvov, Edwin Ruud, Rolla C. Carpenter, Sadi Carnot, Reuben Trane, and William Rankine etc.
The first comfort air conditioning system was designed in 1902. It happened after multiple inventions in Heating, Ventilation and Air Conditioning technology.
This invention of comfort air conditioning was done by Alfred Wolff. Alfred designed this comfort air conditioning system was for the New York Stock Exchange.
Meanwhile, Willis Carrier invented the process AC unit in 1902. Willis designed this process AC unit for the Sacketts-Wilhems printing company.
The first-ever Heating, Ventilation and Air Conditioning training was introduced by the Coyne College in 1899.
To discover the full Heating, Ventilation and Air Conditioning technology there were many inventions and discoveries along the way that designed multiple components of this Heating, Ventilation and Air Conditioning technology.
The industrial revolution and the inventions of the Heating, Ventilation and Air Conditioning components happened parallel. So the industrial revolution also prompted various discoveries in the Heating, Ventilation and Air Conditioning technology process.
Apart from the industrial revolution other activities such as new methods of modernization, system control, and higher efficiency also began in that time by various companies and inventors across the world.
These are some of the basic parts of the Heating, Ventilation and Air Conditioning technology –
- Evaporator coil
- Heat exchanger
- Condensing Unit
- Refrigerant Lines
Use of HVAC
The main use of Heating, Ventilation and Air Conditioning technology is to make a comfortable environment that seems luxurious indoor and in vehicles as well.
So the main purpose of the Heating, Ventilation and Air Conditioning Technology is to provide proper ventilation, thermal comfort etc.
What is the difference between AC and HVAC?
If the difference between HVAC and AC is understood in simple language, then AC means air conditioning, usually, this device works to keep our house, workplace or car cool.
While you can also use HVAC in all these places, and its advantage is that it can keep a house, office or car cool as well as warm, and when needed, only Can also serve as ventilation equipment.
So you can understand that where you can use AC only in one season i.e. summer days, you can use HVAC throughout the year.
To cool the house during summer, to heat the house during cold days, and also as a ventilation device when needed.
CFM full form in HVAC
The full form of CFM is Cubic Feet Per Minute in HVAC.
Cubic Feet Per Minute (CFM) is the measurement of airflow volume.
CFM gives us the calculation about how many cubic feet of air pass by a particular stationary point in one minute.
For example, A 3 Ton HVAC has 1200 CFM of airflow.
