Unbelievably, commercial HVAC is tricky. If you thought residential HVAC systems were complex, you’re in for a surprise. Similarly, vents find their way through, selling for a superb airflow. Each ductwork has HVAC duct connectors to connect ducts for better building airflow.
That’s why, with this guide, you will get the information you need to stay on top of everything HVAC in your building. It will keep your utility costs of HVAC and repair costs low.
About Commercial HVAC System
A system has the same goal as a residential HVAC system. It provides its building occupants a comfortable environment throughout the building.
There are fans in ventilation systems for air circulation. It introduces the ductwork to outside air, filtering it for reuse. It keeps CO2 levels below 1000 molecules per million.
An effective ventilation system reduces odors, dilutes gases, and prevents diseases. Without it, unwanted particles would block the air, promote mold and mildew growth.
How does it work?
According to Air Duct Repair and Replacement Suwanee services, to control the climate in a commercial building, you need three things:
- Warm or cool air
- A distribution method
- Ventilation Controls.
How Commercial HVAC Differs From Residential HVAC
Size
It’s said that HVAC systems should ventilate larger structures as compared to residential HVAC systems. However, If you think its components are much larger than expected, you’d be right. Thus, A residential design is a stand-alone unit, but a commercial system is modular. However, its components are close by to ease their installation and maintenance.
Location
The indoor unit, such as the furnace, is usually located in the basement, closet, or attic. Therefore, the outdoor unit is outside in the backyard or on the side of the house.
Economizers
Did you know that these could be the best-kept HVAC duct connectors secret? They remove heat from the building by bringing in cool air from outside.
Zones
Air Duct Cleaning Suwanee usually states that HVAC systems make up a slew of packaged units. Thus, Each has its thermostat, allowing for various indoor climates/zones to coexist in the same building.
Yet, it enables complete customization by separating each area from the others. Further, To minimize disruption, technicians can repair one zone at a time.
Ventilation
Because of the larger size of a commercial building, ventilation is more complicated. Thus, Smaller residential buildings have more windows per square footage. Therefore, making it easier to open them to get rid of stale air. Commercial buildings require fresh air intake and a designated mechanical ventilation system.
Drainage
During the heating or cooling process, HVAC systems extract humidity from the air. Furthermore, It drips into a tray after passing through piping which could damage HVAC duct connectors. Hence, The cost factors affect the brand, type of unit, building size, type of business activities, installation costs, etc.
Maintenance
Commercial systems are generally more expensive to repair. Moreover, HVAC equipment needs a different set of expensive tools with technicians. Thus, You might need maintenance, which is now costly.
Parts in Heating and Cooling Systems
Here is a list of the most common parts found in a commercial heating and cooling system:
- An air handler (or air handler unit AHU). It’s a large box that houses major parts of an HVAC unit. Moreover, these include blower, heating/cooling elements, sound attenuates, and dampers.
Most units come in a metal box made of galvanized sheet metal. It makes circulating air part of the ventilation system.
AHUs
So, AHUs are for indoors or outdoors. Thus, according to Air Duct Repair and Replacement Suwanee, they come in two varieties:
- Packaged units
- Rooftop units.
- Did you know? Dampers control the flow of air. Thus, Volume control dampers adjust the volume of the airflow. Furthermore, dampers may close a duct if they detect smoke or fire.
- Duct fittings and configurations are in-charge of balancing airflow and equalizing duct pressure. These include ells, tees, and reducers.
- A vent cap is another type of ductwork fitting. It protects the open end of a ductwork vent stack. Each fitting and configuration contributes to the overall performance of commercial ductwork.
- Another type of outlet is a register box (known as a floor box). According to Air Duct Cleaning Suwanee. It’s a galvanized steel grille with moving parts.
- The plenum is arguably the most critical component of any ductwork. It’s an air distribution box for an HVAC system’s central airflow unit.
- A High-Efficiency Takeoff (HETO) is a tap. It is used on a rectangular duct. It increases the upstream side of the fitting. Its design allows the most air to flow downstream, creating a balance and saving energy.
- You’ll find vents installed in the ceiling. Most of them have their edges aligned with the opening in the above duct. Vents allow air to flow into the rooms below as it passes through the commercial ductwork.
- Because the ventilation system is usually made from a metal sheet, it can easily withstand a wide number of expressions. It includes working on a wider range of temperatures.
Choosing The Best Duct Connector
There are several important factors to consider when deciding which flexible duct connector is best for your job. At what pressure will the duct system operate? Will the equipment be installed inside or outside the building envelope? What are the typical minimum and maximum temperatures to which the ductwork is subjected? Will the flexible duct connector be exposed to other airstream constituents (chemicals, for example)? What is the length of the distance you need to span? These are only a few of the critical factors to consider.
