10 Important Industrial and Commercial HVAC Parts Of HVAC System
Industrial and Commercial HVAC Parts: An HVAC system is an intricate web of different components and sub components, each one of which is equally important. Despite the fact that there are many Industrial and Commercial HVAC parts in the overall system, the most critical ones are only 10. All of them perform different functions, so it may be impossible for the entire system to function without any of them.
Listed below are the top 10 main Industrial and Commercial HVAC parts of an HVAC system in a commercial or industrial setting.
- Air conditioner
- Thermal expansion valve
- Air handler
- Terminal units
- Ductwork and ventilation system
In simplest terms, a thermostat is simply a device that regulates temperature so that specific areas of the building can be cooled or heated as per the parameters programmed into it. Right now, there are various types of thermostats available in the market.
2. Air Conditioner:
As the name implies, air conditioners do what they are supposed to do; they provide cooling to the property. In spite of this, one should keep in mind that ACs in commercial and industrial facilities are completely different from ACs in residential homes. They are distinguished by the fact that the former is made for heavy-duty tasks, and therefore is much more complex in its build and design.
In contrast, the compressor circulates refrigerant between the evaporator and condenser coil. Additionally, liquid refrigerant is also converted to gaseous form, and vice versa with the help of compressor. As a rule, refrigerant is in the form of a gas, which is its natural state. In order to increase its temperature, the compressor compresses the gas. The cooling process begins in earnest when it moves on to the condenser.
Now, for the the heating side of Industrial and Commercial HVAC parts, we have the condenser. This part, known as the heat exchanger, is responsible for transferring heat from the interior of the building to the exterior of it. Aside from that, it should also alter the physical state of refrigerants. In contrast to the compressor, the condenser is much more directly involved in this process. Heat pumps also work in opposition to AC, by collecting heat from the outdoors.
5. Thermal Expansion Valve:
Although the name may suggest otherwise, the thermal expansion valve plays a vital role in the air conditioning process. Normally, it can be found either inside the air handler or near the evaporator coils. The purpose of this particular HVAC part is to lower the pressure on the liquid refrigerant so it can expand and become gaseous again.
6. Air Handler:
Usually, air handlers are primarily used as housing to house other HVAC components like evaporator coils, blowers, and subcomponents e.g. racks, sound dampeners, dampers, chambers, heating and cooling elements, etc.
7. Terminal Units:
The terminal units are used to house the blower, coils, and air filters within the system. However, unlike other Industrial and Commercial HVAC parts, these have a range of sizes to choose from. You can usually find them near duct returns or ceiling walls.
The chiller is one of those Industrial and Commercial HVAC parts that aren’t strictly necessary, but they do make a significant difference in the operation of the system. In various parts of the building, chillers are utilized in order to lower the temperature throughout.
Furnaces are part of the heating system. By using the blower, it distributes the heat to the vents. It actually works in opposition to the air conditioner.
10. Duct Work + Ventilation System:
Last but not least are the ductwork and the ventilation system. They are responsible for not only connecting the entire HVAC system, but also circulating air throughout the building. Contrary to the previous components, however, they do not have any technological features.
