What Is Meant By The Term “HVAC”?
As most people are already aware, the acronym “HVAC” stands for Heating, Ventilation, and Air Conditioning. But knowing the words and understanding the extent of their meaning are two different things. After all, the individual systems that constitute an HVAC system each have their own complexities, subcategories, and specific service requirements. Having a deeper understanding of each system and how they all work together to form a whole is especially useful for the homeowner, who will inevitably experience some sort of problem with their own HVAC system at some point. Keep reading to learn all about the individual elements of HVAC.
Heating Basics
In the context of HVAC, heating almost always refers to central heating - generating heat in one central location to be delivered throughout the rest of the building viaducts or other conduits. There are many different forms of central heating used today, and nearly as many fuel sources are used to power them, including natural gas, propane, electricity, and even oil.
Gas or electric furnaces are perhaps the most common type of heating system. These use gas burners or electric heating elements to heat air, which is then distributed throughout the building. Boilers use a similar method, but the heat is instead transferred to water, which gets piped through radiators or baseboard heaters to provide warmth. Electric heat pumps draw existing thermal energy from the outdoor air and amplify it to heat indoor air.
The Ventilation System
Ventilation is, in many ways, the key to central heating and air conditioning systems. Without it, hot or cold air would largely be confined to the room in which it was produced. The primary function of the ventilation system is to deliver hot or cold air throughout the building and bring it back for recirculation.
The critical elements of the system are the blower unit, ducts, air return, and air filter. The blower moves air through the ducts while the return vent draws air back in, and the filter traps dust and other debris to prevent it from damaging the unit or being blown around the house. The ventilation system also plays a critical role in removing humidity from the air with the help of the filter.
Principles of Air Conditioning
Air conditioning is an indispensable part of an HVAC system. It also helps to keep indoor humidity levels down, but its main purpose is to remove warm air from the inside and bring in cool air from the outside. This is typically accomplished using two units - one inside and one outside. This employs the same process as heat pump heating systems, only in reverse. Essentially, refrigerant lines transport thermal energy between the indoor evaporator coils and the outdoor condenser coils, releasing warmth outside and cooling the air inside.Due to the complexity of HVAC systems, there are plenty of opportunities for things to go wrong. And with the interconnected nature of each subsystem, it’s crucial to make sure they’re all operating correctly and efficiently. This is why regular maintenance visits are the best thing homeowners can do for their HVAC systems.
