Different Types Of Hvac Systems
The components and design of Heaving, Ventilation and Air Conditioning (HVAC) systems
differ mainly on the basis of their application, especially in the case of Commercial & Industrial HVAC. Different types of settings including manufacturing units, warehouses and multi-story office buildings all have special climate control needs and provide a wide range of designs, installation and maintenance challenges to the building engineers and maintenance staff.
Forced and Radiant Air Commercial & Industrial HVAC
Forced and Radiant Commercial & Industrial HVAC systems consist of a two main methods for conditioning temperature of the interior area. The conventional radiator is the ideal radiant HVAC system, as it transfers hot or cold temperature through a number of tubes or pipes that carry hot or cold water. This type of tubes or pipes are generally buried under floors or within the walls. In a radiator, the tubes can be seen as a part of a stand-alone system.
The forced air Commercial & Industrial HVAC systems would rely upon a network of ductwork along with several fans for circulating the air in and out of the building. When the air gets sucked out of the building, the air conditioner coils or the furnace coils would condition the air, change the temperature and push it back into the ductwork.
Multi-Zone and Single Zone Commercial & Industrial HVAC
Multi-zone and single zone terms refer to the volume and the system used for controlling a single
Commercial & Industrial HVAC system. In the case of a single zone system, there is just one control panel for the entire system. This system can be spread across several rooms and even floors. In the case of a multi-zone system, there are multiple controls, just like a programmable sprinkler mechanism. The different zones created in the rooms and floors would experience different temperature levels as per the preference of the programmer.
Even though there is a good chance that the single zone Commercial & Industrial HVAC system can heat up certain rooms more than others, it would require lesser amounts of equipment and therefore, it doesnt cost as much as the multi-zone system. In the case of the multi zone system, it would enable the occupants in a zone to change the temperature of the room without making any impact on the other zones. If the occupants in a zone are getting afternoon sun, they can lower the temperature of their room without ever altering the temperatures in other zones that are receiving shade.
Steady and Variable Volume Commercial & Industrial HVAC
When it comes to this type of Commercial & Industrial HVAC systems, the terms constant and variable volume stands for the air volume flowing through the system. The constant volume HVAC systems would provide a constant air volume through the ducts. However, the variable systems would keep adjusting the air volume that flows through the ducts to keep altering the temperature of the room.
The constant volume Commercial & Industrial HVAC system would keep changing the temperature of an area by heating or cooling the air that flows through the ducts. On the other hand, the variable volume HVAC system keeps changing the temperature of the room by increasing or reducing the flow of hot or cold air through the space.
These are the leading types of
Commercial & Industrial HVAC systems available on the market. You can choose the system to create multiple zones with a centralized control panel for altering the temperature of each and every room. On the other hand, you can choose a relatively inexpensive system by purchasing a single zone system where you have the need for creating and controlling the temperature of only a single zone in your building. Whichever system you want to choose, the guide given above can be of significant help in choosing the right system. Therefore, the next time you want to purchase a Commercial & Industrial HVAC system make sure to consult this information.
