How does HVAC work in an office building?
Commercial buildings need HVAC systems. Well-functioning HVAC systems are essential for commercial buildings such as restaurants, hospitals, schools and hotels. They keep their occupants comfortable, no matter what season it is.
What's an HVAC System?
HVAC stands for Heating, Ventilating, and Air Conditioning. HVAC systems control buildings' temperature, humidity, and air quality to create a comfortable environment.
Now that you are familiar with their purpose, the next question is how it works.
Heating is achieved by heating the building with radiators or supply air systems.
Ventilation involves removing contaminated air from the building and maintaining clean air. It circulates the air inside and removes humidity. Ventilation is often performed by mechanical systems such as fans. Cooling systems are also helpful in maintaining the proper humidity and temperature within commercial buildings.
What Does a Commercial HVAC System Do?
Interconnected HVAC systems are used in commercial buildings to provide heating, ventilation and cooling for individual floors or other areas. Heat pumps are used in commercial HVAC systems to heat the air. Water source heat pumps are pipes that transport water throughout a building.
Rooftop units are usually located on the roof but can also be found on the ground. They are responsible for circulating the conditioned air throughout the building. Cool water is generated by chillers and distributed through pipes to cooling coils. There are two types of heaters in commercial HVAC systems: Radiant heaters, which use infrared radiation, and furnaces, which burn fuel to heat air.
What Types of HVAC Systems are Commercial Buildings Using?
The majority of commercial buildings use one or more of these HVAC systems:
Central HVAC systems are a unit that is located in one area or zone and supply all HVAC requirements for a commercial building. These systems use water to cool and have extensive ductwork for air distribution. A centralized system offers many benefits, including excellent load management capability and easier control. They are also more challenging to manage and maintain.
A packaged HVAC system typically includes one unit's heat pump, air conditioner, and fan coil. These systems are most commonly used in commercial buildings with limited space. The thermostat controls the system, and optional accessories such as air quality enhancers, cleaners, and ventilators are also included.
Decentralized systems are often used to describe individual HVAC systems. These HVAC units provide heating, cooling and ventilation in commercial buildings. They use multiple units at different locations. These units are simple to manage but not recommended for large commercial buildings. Individual HVAC systems include rooftop units, air-to-air heaters, and AC units for offices or rooms.
Commercial buildings have unique heating, cooling, and ventilation requirements that differ from residential spaces. It is essential to find a reliable HVAC contractor that understands commercial HVAC systems.
