Commercial HVAC systems are astonishingly complex. Their primary purpose is to offer a comfortable working environment for everyone in the building. It is achieved by getting rid of contaminated air through filtration or exhaust systems, managing energy, and taking air from outside to control indoor temperatures.
While most people may find that the systems are quite complex, it is important to have a clue on how they work. It might help out loads in case a problem crops up in the future.
Essential Parts Of The Commercial Systems
The systems are made up of different parts that may include:
- Fans- these are responsible for the circulation of the supply of air as well as return air.
- Air devices- such as outlets and inlets.
- Supply air ductwork- it is where the heated air flows through after it is released from the fans.
- Auxiliary heating device- it can be an electric heating system or a natural gas heating furnace.
- Filtering sections- their main work is to remove any dust particles and dirt from the system and in the air.
- Controls- they handle the regulation of the flow of air, and they also start and stop the unit.
The above list is not exhaustive as many other parts work together to warm your business premise during cold weather.
How Do The Systems Function In Huge Buildings
Taking a look at standard commercial HVAC systems, you will note that burners in the system generate combustion gases when the heating system is turned on. From here they are transported to a heat exchanger.
Air is warmed when it is blown across the heat exchanger. Warm air is finally carried through various ducts to heat up the whole building.
What Are The Factors That Define Your HVAC System
All HVAC systems come with some standard components. However, there are different ways of optimising and implementing HVAC systems. When choosing the system to use some of the elements that contribute to efficient performance include:
- Fuel that is responsible for heating is it gas, oil or electricity?
- The coolant- is it an air conditioner, chiller, gas air conditioner or electric heat pump?
- How is the cooling or heating delivered through space- Is it a water system or ducted air?
- What is the type of ventilation approach used? Does the system have a dedicated ventilation system used?
Types Of Commercial HVAC Systems Available
Commercial buildings can take advantage of various interconnected systems that offer cooling and heating for individual floors as well as other areas. Some solutions that you may see in the large-scale systems include:
- Roof top units- these are installed on the ceiling and some of the ground. Conditioned air is then ducted into space. A majority of businesses prefer to use this kind.
- Heat pumps- they extract heat from water or air before it is heated. They work just like refrigerators but in reverse. For the water source heat pump, the pipe transports the water via the structure in a bid to supply the heat pump.
- Heaters- these are available in two types- hot air furnace which burns fuel to heat air and the radiant heaters that make use of invisible infrared radiation to directly heat the objects.
- Chillers- they generate cool water that is distributed to air cooling coils through sophisticated piping systems.
