Properties of a Commercial HVAC Parts

Read Time:5 Minute, 8 Second

Have you ever imagined what makes up the gigantic HVAC systems on the rooftops of office buildings or its surrounding? They comprise several essential HVAC parts to function correctly. While the functions of some components are unmistakable, others may be unfamiliar.

Each component relies on the others to maintain the system’s integrity and proper operation. If any of these parts fail, the whole system could be jeopardized, or at the very least, its performance will decrease. You should know the essentials if you oversee a facility with one of these HVAC systems.

HVAC Parts

So, this information will discuss the function, purpose, and potential future repair needs of the essential HVAC components. After reading this, you should understand the affected HVAC part and who to contact if you need commercial HVAC services.

Unit Compressor 

The HVAC system’s heart is the unit compressor. This unit component recirculates the refrigerant between the closed loops of the condenser coils and the evaporator. Most compressors are located outside, and their main job is to alter the refrigerant so that it can enter the condenser.

The compressor needs to be serviced regularly. During these maintenance visits, technicians will inspect the compressor for signs of wear, faulty wiring, and other concerns that could result in a breakdown.

Compression failures typically result in the need for a new part, and depending on the extent of the damage, the entire HVAC system may have to be replaced. That’s why proper maintenance of the compressor is so crucial.

Air Handler

The air handler, composed of most HVAC systems and has a blower to distribute air throughout a structure, should also be included. The evaporator coils will be stored in the air handler.

The heated air in the building or dwelling is sent to the air handler’s evaporator coil through a blower. After absorbing the air’s heat, the refrigerant condenses into gas and returns to the compressor.

The blown air is then recirculated throughout the building. The air handler’s HVAC system includes tracks, dampers, sound attenuators, racks, heating, and cooling components, etc. The evaporator coil is the most fragile component here, necessitating frequent upkeep.

The Terminal Unit

This part of a business HVAC system regulates how much-conditioned air is piped to different rooms. Coils, a filter, and a blower are the three main components of most terminal units.

Debris, like dirt, pollen, and dust, is filtered out by the filter. As filters become clogged, airflow is restricted, negatively impacting the system’s efficiency. Filters can be cleaned or replaced regularly to improve efficiency, but cleaning them at least once a month is recommended.

Routine filter cleaning may be required if the structure is in a region prone to high winds and airborne particles.

The Chiller

Chillers and other HVAC system components will also be installed in more significant commercial buildings. Chillers can be air- or water-cooled and typically placed outdoors. These components cool the fluids circulating through the pipes of a structure.

Water-cooled chillers are typically used in structures where cooling may be required for long periods. These machines use recycled water to transfer heat and bring cold water from an exterior cooling tower.

The Furnace

After receiving a signal from the thermostat, the furnace will begin coordinating the heating process. Then, the burner is lit after the gas valve is turned on.

After passing through the generator, the hot air is transferred to a heat exchanger. It is heated before being pushed into the ducting and distributed to various sections by a blower.

The Thermostat

The thermostat is also an essential part of the HVAC system, wired into the network. It controls the unit’s primary features, such as sending the signal for the HVAC system to either heat or cool the air, depending on the thermostat setting.

A sensor inside the part can determine whether the cooling or heating system should be activated. In most cases, a building with separate thermal zones will also have individual thermostats for each zone.

The Air Conditioner

A commercial HVAC component functions similarly to a home air conditioner in that it removes heat from the interior of a building and vents it outside while also recirculating and dehumidifying the air.

A split system air conditioner is the most common type, consisting of parts installed inside and outside the structure. The refrigerant removes the heat from the air as the init pulls it in from the building.

The air conditioner cannot adequately chill the building on its own. Proper temperature control depends on properly operating all other components and HVAC subsystems.

The Condenser

This external HVAC component facilitates heat exchange throughout the system. Using a network of pipes and a fan, it is often responsible for venting the building’s interior heat to the exterior.

Cooler outside air sweeps over the condenser’s coil, drawing heat from the high-pressure, high-temperature refrigerant and expelling it into the atmosphere. Once this happens, the thermal expansion valve will be exposed to the refrigerant.

The Thermal Expansion Valve

That’s a crucial component of the system as well. The expansion valve reduces the pressure on the liquid refrigerant, allowing the vaporized refrigerant to enter the evaporator coils.

The evaporator coils are the most common location for the thermal expansion valve. However, it can also be found inside the air handler.

The Duct System

The last function of an HVAC system is to distribute the conditioned air to the various rooms. They are also responsible for reintroducing the system’s original, unconditioned air.

A professional should also clean these ducts regularly as they will need maintenance.

Need An Expert?

Maintaining a well-functioning HVAC system requires familiarity with its fundamental components. Therefore, when problems arise, managers should avoid attempting to fix them themselves. Repairing a heating, ventilation, and air conditioning system is not a DIY project, no matter how minor the issue is.

As the leading commercial HVAC contractors, we are here whenever you need us for repairs or maintenance. Our teams will see that your HVAC system runs smoothly from start to finish, allowing you to reap the benefits of a properly functioning system without interruption and interference.
