What Exactly is an HVAC System?

You may have heard the fancy name HVAC; You vaguely know it has something to do with heating up and cooling down. But you’ve never really understood the basics or why someone decided to just lump up equipment for increasing temperature and that for decreasing temperature, putting everything under one single nomenclature. Well, you’ve stumbled on the right page. We are here to rescue you from your semi illiteracy about HVAC systems.
You may ask “why do I need to know about HVAC systems”. The answer is that there are a couple of legit reasons why you shouldn’t be in the dark, they’re:
1. Knowledge is cool: Ignorance isn’t trust me.
2. You’re most likely using an HVAC system: Either it’s at home (on a small scale) or at work (on a larger scale) or in between home and work (in your vehicle); There’s definitely an HVAC system that’s been used to ensure the quality of air in your building or car and to maintain pressure between spaces. Yeah, what were we talking about? You need to know about HVAC systems since they’re all around you. The knowledge will help you to use them safely and at least know when to call the attention of maintenance staff.
3. No one knows the future: Yep, you could wind up having to switch industries and work as an HVAC professional. The knowledge you’ll get here could save your life and career. Just joking, you definitely can’t learn nearly enough here to start a career in HVAC, but this is at least a step in the right direction.
We’ll cut to the chase now. What is HVAC? HVAC is an acronym for Heating, Ventilation and Air Conditioning. As the name implies, HVAC systems are used to achieve temperature control basically making used of ambient air. HVAC systems help to regulate thermal conditions to suit human comfort and also ensure the quality of air present within a closed environment. We shall take a brief look at the various components in isolation:
Heating: Getting rooms warmed up during winter is a perfect example of this. Heating is basically bringing about an increase in temperature. Various equipment can be used to generate heat, the major one is a furnace (which may be powered by various solid fuels, liquid fuels or gaseous fuels). Many modern heaters are more likely to be powered by electricity. The heat is circulated around the target space either through hot water or steam. Radiators and other types of heat exchangers are also used in circulation
Ventilation: The real definition of this may be a little difficult to keep up with. In simple terms, we can just define ventilation as “air cleansing” removing odour and contaminant from airspace by letting in fresh air from an external source. This is basically what you try to do when you open your windows after a pollution.
Air Conditioning: This aspect involves the process of cooling an environment by the use of refrigerants.

Now that’s basically what HVAC systems involved. Be sure to do some further reading to learn more.  More Info
