Understanding How HVAC Systems Function

Nov 14

There's nothing more soothing on a hot summer day than entering an air-conditioned space. What is happening inside your home to help keep your home cool?

 

The air conditioning system in the building is part of an overall system called the heating, ventilation, as well as air conditioning (or HVAC, which stands for heating, ventilation and air conditioning system). The heating and Cooling Colorado Springs system in your house is in essence an enormous machine that comprises an air conditioning system, a thermostat, as well as a variety of other devices which cool or heat the air.

 

Knowing the basics of the way this system operates is extremely helpful in deciding whether to repair the issue or even replace it. This article explains what happens behind the behind the scenes to keep your home cool in the summer and warm in winter, in layman's terms.

 

Ventilation duct system (V)

 

Vents for supply and return (also called registers) as well as ductwork, filters and a circulating fan form the ventilation component in your HVAC unit. The circulator draws air from your home via return vents, through the ductwork, and over the cooling and heating systems. The air is then pumped back to your rooms via supply vents.

 

This system, also referred to as a forced-air system is the basis for the heating and cooling system in your house. But, before we dive deep into the details of the cooling and heating processes it is important to learn a brief physics course is necessary.

 

Heating Pumps for Heat Systems

 

Although heating systems for domestic use differ from their counterparts in A/C but the basic concept remains the same. The air is inserted through the ductwork of the HVAC unit, then heated and circulated around the home. There is a lot of variation in the manner that the air is heated.

 

Certain technologies, like heat pumps, are basically reversed systems for air conditioning. They can be used to cool and heat by switching the cold and hot coils. The function of the heat pump is as described above when it is it is in the air conditioning mode. The cold and hot coils are switched in heating mode. The heat pump pulls in air from the outside and then delivers the heat within your home. Certain heat pumps draw warmth from the ground.

 

Other options, like furnaces, heat the air through burning the fuel (oil or natural gas).

 

Heating and cooling units, as well as Central Air Conditioning vs. Heat Pumps

A lot of homeowners are unsure how to cool and heat their home with the use of a heat pump or a combination furnace with a central AC.

 

The advantages of heat pumps are:

 

  • Since a heat pump is able to simultaneously heat and cool the air, it only requires one unit maintenance.

  • They are also more efficient in terms of energy consumption than furnaces and central air systems and all types of systems can be found in various efficiency levels.

 

Benefits of a furnace as well as central air conditioning:

 

  • Since each component is only operational for a specific amount of time during the year, combinations typically last longer.

  • While this could be subject for change over time, in the past, natural gas or oil that is used in furnaces has been cheaper than electricity.

  • The majority of experts believe that a heat pump is the most suitable option when your climate isn't prone to freezing temperatures. A central air and furnace system however tend to be the best option if you live in an area that has long winters and cold.

 

Hybrid cooling and heating systems

 

Alongside the two options mentioned above, a third hybrid system is now emerging as a preferred choice for homeowners. The hybrid heating system is comprised of two furnaces and a heat pump and the other depending on the temperature outside.

 

The system calculates what temperature it's more economical to run the furnace or the heat pump (the economic equilibrium point) and then switches between the two when the temperature increases or decreases. Based on the environment you live in the hybrid system could be the ideal choice for you. To help you assess your options, talk to an experienced HVAC contractor.

 

A qualified HVAC expert should fix the condenser that is malfunctioning.

 

You'll be more confident about identifying when and where issues arise now that you've got an understanding of the way HVAC systems function. You'll also be more comfortable when talking to the HVAC contractor or considering your choices.
