Hvac Systems Main Parts And Functions

Of all the different ways for people to heat and cool their homes, by far HVAC systems are the number one choice. This comes as no surprise because HVAC systems do their heating and cooling jobs very efficiently, are very easy to maintain and also are very simple top operate. It is an essential appliance that despite the fact its found in many homes, not many people really understand how they work. Here is an overview of the main parts found in HVAC systems and what role they play in the functioning of HVAC systems as a whole.

1. Combustion Chamber

Of course one of the main functions of HVAC systems is the production of heat to warm a home or business; producing the heat for this job is the main function of the combustion chamber. Most forced air furnaces produce heat by means of a fossil fuel such as natural gas, propane or oil. The combustion chamber is made up of parts that bring in both the fuel source and air and then mix them together. Once these are mixed, they are then ignited by a small flame (pilot light) or a super-hot electric coil to start the mix on fire and in turn produce the heat that an HVAC system then distributes to the rooms in the structure.

2. Air Conditioning Component

It must be noted that not all HVAC systems have an air conditioning component. When they do it makes a convenient system that keeps a home or business very warm during the colder months of the year and much more comfortable and cool in the hot summer months too. The cool air that is produced by the system conveniently is distributed to the home or business by the same means that distribute the heat that the system produces.

3. Forced Air System

It was mentioned that the heat and cool air that HVAC systems produce needs to be distributed to the various places in a home or business that need it; this is the function of the forced air component of the system. The unit will have a large fan that brings the air into the system to not only move the warm and cool air but to also supply the air to the combustion chamber to help produce the flame. There are hundreds of feet of ductwork in the walls and floors of a structure that bring the heat or cool air to where it is needed.

4. Controls

No forced air furnace can work without the essential controls that tell the system how it needs to operate and what the desired temperature is for the structure that is being cooled or heated. Controls can be very simple and do such things as just turn the system on and off or the can be so sophisticated that they can heat and cool individual areas to different temperatures and control the exact time when the HVAC system comes on and off. Like any type of appliance, HVAC control technology has come a very long way over time.

HVAC systems are very essential to home comfort to say the least and there really is no better or easier way for a person to both heat and cool their home or business.
