HVAC stands for heating, ventilation, and air conditioning. It is a system that regulates and moves heated and cooled air throughout residential and commercial buildings, from homes to offices to indoor stadiums. The main objective of having an HVAC system in a building is to make occupants feel comfortable, healthier, happier, and more productive. HVAC systems also improve indoor air quality through mechanical ventilation and filtration.
HVAC systems can provide heating, cooling, or both. Most commonly, HVAC systems are forced-air systems that provide heating and air conditioning as the air circulates through the system. Duct systems, such as central air conditioning, have a central unit that treats the air, and a blower that circulates treated air throughout a building’s ductwork and into the main living space. The selection of HVAC systems in a given building will depend on the climate, the age of the building, the size of the building, and the desired level of comfort.
In summary, HVAC systems are designed to achieve the environmental requirements of the comfort of occupants and a process. They are used for controlling the overall climate in a building, balancing the temperature to make the inside cooler or warmer during the cold season. HVAC is an important part of residential structures, commercial buildings, vehicles, and marine environments.
