How Is an RTU HVAC Different from Other HVAC Systems?
HVAC contractors often recommend an RTU HVAC unit as a new addition or replacement option for smaller commercial buildings. RTU stands for rooftop unit, and as the name suggests, it is HVAC equipment installed on the roof of a structure. The flat roofs of stores and other commercial buildings have enough space to accommodate HVAC equipment easily. The standalone unit is the most popular and effective commercial heating and cooling solution. It works like other systems, heating and cooling a space by treating and circulating the air that passes through it.
How RTU HVAC differs from other HVAC systems?
RTU HVAC systems are positioned on a roof, as can other units like water-cooled chillers or the condenser of a split-system air conditioner. Conventional HVAC units have their components set separately indoors and outdoors. What sets a rooftop unit apart from other HVAC systems is the inclusion of all of its parts required for heating and cooling in a single cabinet. It is also known as a packaged unit and uses ductwork and registers to transfer the heated and cooled air to different building areas and is equipped with return registers to pull the air back into the system.
A typical rooftop unit comprises of a large metal box that contains:
Evaporator coil to absorb heat
Condenser coil to release heat
Intake for outside air
Compressor
Supply fans
Heat source
Benefits of choosing RTU HVAC systems
Here are a few reasons why several business owners choose rooftop HVAC systems over others:
Saves indoor space
Since RTU’s, except the ducts, are installed on the top of a commercial building, it frees up the expensive indoor space for other purposes.
Better energy-efficiency
Rooftop HVAC systems are highly energy efficient as all of their components are configured and assembled in a factory under optimal conditions. It increases their efficiency, and they use less power, resulting in low energy bills.
Simple installation
RTU HVAC systems are easy and affordable to install since most parts come pre-installed from the factory.
Quieter operation
All the components of the RTU HVAC systems live atop a roof, making it less disruptive. The system’s operating noises are not noticeable, hence, minimizing the disturbance indoors.
Simple to diagnose issues and perform repairs
As all the components are packaged together, it offers the HVAC technician easy access to the rooftop unit for performing required maintenance and repairs.
Drawbacks of RTU HVAC systems
Though it offers various advantages, rooftop HVAC systems are not ideal for every business.
They are ideal for installations only if the roof is spacious and easily accessible.
Though built to withstand the elements, rooftop installations make these units more prone to weather-related damage than the systems installed on the ground.
RTU HVAC systems work best only for buildings under ten stories.
Improper installation can damage the roof membrane due to the unit’s weight.
As the whole system is situated outdoors and away from any disturbances, it increases the possibility of animal and bird infestation that can cause severe damage to the system.
Since the RTU HVAC system is located out of sight, it is likely to suffer negligence.
Large, open spaces are ideal for RTU HVAC system installation. Contact an HVAC contractor to select the best unit to match all the business needs.
