HVAC: Heating Ventilation and Air Conditioning

HVAC is an abbreviation of Heating Ventilation and Air Conditioning. It is a sequence of orders of technologies mostly used to manage room temperature, humidity, and Airflow within a defined region. It is developed to make available for use thermal comfort and acceptable indoor air standard. In mechanical engineering, the HVAC system design is the subject. It is worked based on the fundamentals of thermodynamics, fluid mechanics, and heat transfer. For both domestic and commercial buildings, HVAC systems can be used. It consists of central air conditioning, heating, and ventilation system.

To design and develop well-furnished and extremely comfortable or elegant surroundings within a building or in vehicles, HVAC technology is used which is very fundamental and significant in the creation of methods to large industrial and office buildings. The primary example of this technology in use is Vehicles, Restaurants, Schools and Colleges, Business Offices, Hotels, Shopping Malls, etc.

Its chief aim is to make available for use thermal comfort, proper ventilation to abolish displeasing smell and non-essential moisture within the sensible installation, operational and maintenance costs.


HVAC is a set of the order of technologies. It is worked based on the inventions of some famous scientists like Nikolay Lvov, Michael Faraday, Willis Carrier, Reuben Trane, James Joule, William Rankine, Sadi Carnot, and lots of others.


It can reduce the risk of water loss and dehydration and also they can be obliging in preventing heat strokes.

It enhances air standard inside the building and creates a much healthier surrounding. It can filter out pollen, dust, and other allergens available in the surrounding.

In one unit, both heating and cooling consist of the HVAC system. This solitary saves construction space, installation time and fees, and power usage which is needed.


  • It can make a user skin loses its moisture, as a result of that becoming sensitive and dry. It can also make the annoyance happen and dryness of the mucous membrane.
  • An immediate change in temperature has been shown to aggravate the symptoms of numerous respiratory diseases.
  • Not cleaning the HVAC system can make happen the buildup of dust, bacteria, and pollen in the air filters. This will remarkably increase the risk of asthma attacks and respiratory tract infections.
