What’s HVAC And How Does It Impact The Environment
By Jon D Aguilar
“Green” is the latest buzzword in the HVAC industry. These systems were designed to heat, cool and ventilate air, but this added comfort came with a cost. When chemicals used were found to be harmful to us and the environment, steps were taken to phase them out and use more eco-friendly materials.
What’s HVAC ?
Do you know what’s HVAC ? HVAC is an acronym for Heating, Ventilation, and Air Conditioning. Ventilation may control the flow of air for both heating and air conditioning. However, ventilation also includes many more tasks.
Aside from distributing air that has been heated or cooled, ventilation can encompass all processes for exchanging air inside a given space. It may be necessary to ventilate in order to :
- Refresh Oxygen Supply.
- Remove Carbon Dioxide.
- Eliminate Bacteria.
- Reduce Moisture.
- Prevent Odors.
- Clear Dust.
- Circulate Natural Heat.
That means it happens in one place and is distributed throughout the vents. Modern skyscrapers work by letting hotter air escape through the top of the building while simultaneously drawing in cooler and fresher air from the bottom. This type of natural ventilation is seen as reducing the burden on the environment.
HVAC Systems And The Environment
Speaking of the environmental impact, you may have heard a buzzword associated with HVAC called CFCs (chlorofluorocarbons). There is actually a long history about this issue because of the impact on the ozone layer and ultraviolet rays. Before CFCs, the chemicals used for cooling were often flammable or harmful to breathe. In 1928, Thomas Midgley, Jr. introduced CFCs. This was an improvement at the time.
The agreement to phase out CFCs began as the Montreal Protocol. As of today, all the members of the United Nations have signed it. In total, there have been 196 countries participating. What does all of this mean for you? When you hire an HVAC company to install, repair or upgrade your home’s system, you can choose “green” options. Most companies are now offering lots of ways consumers can help protect their health and the environment. There are also things you can do to keep your system in good shape so that it works more effectively, which saves you money and helps to save the environment.
