HVAC stands for heating, ventilation, and air conditioning.
In data centers, HVAC systems manage the environment and must be designed to operate along with other data center mechanisms such as computing hardware, cabling, data storage, fire protection, physical security systems and power.
There are many different types of heating systems in the HVAC structure. Central heating is generally used in cold climates to heat private houses and public buildings. These systems contain a boiler, furnace, or heat pump to heat water, steam, or air in a main location such as a furnace room in a home or a mechanical room in a large building.
Another element in the HVAC arrangement is ventilation, which is the process of replenishing oxygen in any space to maintain temperature or remove unwanted elements, such as moisture, heat, dust, bacteria, or carbon dioxide. Ventilation involves exchanging the air inside the building with air from the outside and the circulation of air within the building.
The last element in the HVAC system is air conditioning, which removes heat by radiation, convection, and heat pump systems. An air conditioning system provides cooling, ventilation, and humidity control for houses or buildings.
