Typically used for buildings up to eight floors in height, rooftop HVAC units offer numerous incentives as a heating and cooling solution. Ideal for their ease of customization and maintenance, they are also very efficient systems that can be easily adapted to the unique needs of a specific structure.
Understanding the Core Components of Your Commercial Rooftop Unit
Rooftop HVAC units operate on simple scientific principles but are quite complex. Here are the core components of your commercial rooftop HVAC unit:
- Evaporator core: When cooling your building, this is part of the system that absorbs heat from indoors by running air through refrigerant coils.
- Condenser: Functioning as the opposite of an evaporator core, the condenser captures and releases hot air into the outdoors. The refrigerant that has absorbed heat is cycled through coils where its heat is released and cycled out of the unit via fans.
- Compressor: The compressor acts as the intermediary in the HVAC cycle. Taking refrigerant fluid from the evaporator core where heat is absorbed, the compressor then cycles it through the condenser, where heat is released.
- Fans: Throughout the HVAC process, fans play an integral role in how hot, and cold air is directed through a system through the evaporator and condenser.
- Air intake: Whether the rooftop unit is cooling or heating, air will need to be brought in from the outdoors to cycle through the system. The air intake uses a series of fans and vents to direct air toward the heating and cooling sections of the unit.
- Heat source: In a rooftop HVAC unit, the heat source may vary but typically is a fuel-burning system that uses a constantly burning flame to generate heat, which is then transferred to airflow directed throughout the building.
- Exhaust: Every Commercial HVAC unit produces potentially harmful gases that must be safely transferred away from the building via exhaust systems.
The advantages of a proactive maintenance program (PMP) for your commercial HVAC rooftop unit:
- Extended lifespan: A system that’s running efficiently is a system that will last. An Commercial HVAC unit will burn out before the end of its anticipated lifespan because it has not been properly maintained. By proactively keeping it running smoothly, you not only ensure your unit lasts its full lifetime but even beyond it.
- Improved efficiency: When your rooftop unit is proactively maintained, it prevents breakages or anticipated wear, which can cause the system to consume more energy to do the same job. This can save thousands of dollars per season in electricity bills.
- Reduced maintenance: By booking regular maintenance appointments with our team of expert technicians, you are helping to reduce the overall number of visits you will need throughout your unit’s lifetime. This is because anticipating problems before they occur keeps the system healthy and reduces the likelihood of future breakages.
