Commercial rooftop HVAC units are often used to heat and cool smaller buildings. Are rooftop units right for you? The HVAC technicians explain how rooftop HVAC units work and how they compare to other options. They also discuss their disadvantages and advantages.
What is a Rooftop HVAC Unit?
Rooftop HVAC units are usually installed on roofs of buildings but they can also be installed on slabs. Flat-roof commercial buildings have plenty of space above the structure to install the HVAC equipment. HVAC systems can be installed on the roof to protect them from theft, and there is also plenty of ground space.
Packaged units for rooftop HVAC systems are also known as packaged units. All components are contained in one cabinet. Depending on the system, all components of the cooling and heating system are contained within the cabinet housing. Rooftop units are designed to withstand sun, rain, wind, and frost.
Rooftop units are not the same as split systems which have separate equipment that is housed inside and outside. An air handler and furnace are installed inside the building. A heat pump or air conditioner is installed around the perimeter.
How do Rooftop Heating and Cooling Units Works?
Rooftop HVAC units work in the same way as other heating and cooling equipment. They provide comfortable comfort for occupants. These systems are connected directly to the building’s HVAC ductwork. The heat or cool air passes through the system, which distributes the conditioned air throughout interior spaces.
The air hood on the roof allows air to enter. The air hood is shaped like an awning and has an opening below. This allows air to pass through while keeping snow and rain out.
Air flows through dampers to regulate airflow. The system’s filters remove contaminants from the air supply.
Next, the air is heated or cooled using heat exchangers or coils depending on the system configuration.
The fan also circulates conditioned air through the ducts.
Why Rooftop HVAC Units are Important?
There are many reasons why business owners choose roof plant platform.
Space Savings
Commercial buildings have limited square footage. A rooftop unit allows all HVAC components to be installed on top of the building. This frees up space that would otherwise be used by indoor equipment.
Security
Because of the location of their installation, are well protected against theft and vandalism. Ground-level HVAC units are more accessible. If the building is not heated or cooled, copper theft or vandalism can cost businesses valuable production time.
Quiet Operation
Operating noise indoors is less noticeable when all components are located outside the building than when a split system has been in use. Rooftop systems reduce distractions within the building.
Easy Access
Rooftop HVAC units are easier to access for technicians if all parts are in one place. All parts can be found in one place, making maintenance and repairs easier.
Avoid Rooftop Units If…
Rooftop HVAC units may not be for everyone. These are reasons why you might prefer a different type of commercial HVAC system.
Potential Roofing Damage
Rooftop HVAC units can be very heavy. If they are not installed correctly, their weight can cause roof membrane damage.
Storm Damage
Rooftop units are designed to withstand the elements but can be damaged by lightning strikes, strong winds, and other weather-related damages. This damage can be caused by split system components at ground level but is much more common in rooftop units.
