Heating, Ventilation and Air Conditioning (HVAC) Introduction
Heating, ventilation and air conditioning (HVAC) is the technology of indoor and vehicular control to aid environmental comfort. The main goal of the whole process is the achieve thermal comfort and bearable indoor air quality. The whole system is based on the principles of mechanical engineering as it directly related to Thermodynamics, fluid mechanics and transfer of heat.
HVAC is a very essential part of residential areas like housing colonies hotels senior living facilities, medium to large industrial areas and hospitals. It is also used in ships and submarines and in a marine environment where safe and healthy conditions fluctuate depending on the temperature and fresh air from outdoors.
Ventilation aids the process of cleansing the air and provides a high-quality indoor air quality. The process involves control of temperature, replenishment of oxygen and removal of harmful components such as moisture dust smoke hear bacteria Carbon dioxide, etc. Ventilation totally eliminates the unpleasant and unwanted components from the air along with excessive moisture and makes room for outside fresh air to gush in and keeps the circulation of air inside the building and even prevents stagnating of interior air.
