HVAC stands for Heating, Ventilation and Air Conditioning, and is a system that provides heating and cooling to residential and commercial buildings. It is a broader term than air conditioning, as it includes heating, ventilation, and air conditioning systems. HVAC systems can be found in single-family homes, submarines, and other places where environmental comfort is needed. The V in HVAC stands for ventilation, which is the process of exchanging or replacing air within a space.
This provides better indoor air quality by removing moisture, smoke, odors, heat, dust, air bacteria, carbon dioxide and other gases, as well as temperature control and oxygen replenishment. HVAC systems can be classified into central and local systems according to multiple zones, location and distribution. Central HVAC systems are located away from buildings in a central equipment room and deliver air conditioning through a supply duct system. Local HVAC systems can be located within or adjacent to a conditioned area and no ducting is required.
Air conditioning is generally used to refer to systems that are designed to cool the air in your home. Window units and central air conditioning are standard systems that are widely used. HVAC systems can include heat pumps and gas ovens, as well as air conditioning units. This means that HVAC deals with heating and cooling, and includes air conditioning units under its umbrella. Ground source heat pumps, or geothermal, are similar to ordinary heat pumps but rely on the stable and uniform temperature of the earth to provide heating and air conditioning.
At one point in time, a building may be using cold water for air conditioning and the hot water it returns may be used in another building for heating. HVAC systems are milestones in the construction of mechanical systems that provide thermal comfort to occupants along with indoor air quality. Increasingly popular in new construction, these systems use fresh outdoor air to provide high indoor air quality. In conclusion, HVAC stands for Heating, Ventilation and Air Conditioning. It is a system responsible for heating and cooling your home and includes products such as ovens, air conditioners, heat pumps, as well as ducts, thermostats and other home comfort controls. Not all HVAC units are air conditioning units but all air conditioning units are included under the HVAC umbrella.
