electricity mains. A brownout occurs when there is a decrease in voltage from an
electrical power supply. Both of these conditions have serious causes for public
health, safety, the economy, and the environment.
The next topic is climate change and smog which air conditioning is a primary
contributor for. Air conditioners are one of the leading causes in climate change
around the world. Energy given out by air conditioners will play a part in carbon-
dioxide emissions that cause the current problem of global warming. The
government every year tries to find out an efficient way to solve the energy crisis.
Businesses demand that they be more energy efficient as well as make their air
conditioners let out a minimal amount of carbon emissions. Europe has found a
technological system for air conditioning to reduce carbons emissions and be
more energy efficient. This system is called the Daikin‟s VRV and was just
initiated to address all of these worldwide concerns.
Social isolation in this case happens when the temperatures are too hot outside
and instead makes a person stay inside to get cooled by the air conditioner.
Being inside all the time for air conditioning will cause a person to be isolated
from his neighbors and communities, and as well contribute to social, emotional,
and behavioral problems. Being alone all the time is not always a good thing
even when it comes to deciding whether or not to have an HVAC system.
Schools across the country have a tough time trying to figure out how to
distribute their resources as well as investing their money. The EPA in 1995
started the Indoor Air Quality Tools for Schools Program. School districts goals
were to manage indoor air quality and also improve the health and academic
performance of students.
Later on in 2007 the EPA wanted to see how if progress was being made in the
Indoor Air Quality Tools for Schools Program. They visited and evaluated these
three school districts which consist of elementary, middle, and high schools.
These districts received positive results because of improved HVAC rules such
as routine maintenance, cleaning, and construction and renovation management.
Contrastingly, before 1995 the EPA noticed that there were problems in the
HVAC systems. As a consensus of all three school districts, the problems that
happened are cleanliness issues, dangerous and hazardous storage of
chemicals, dampness and mold occurring in the HVAC ducts, as well as pests
and food storage violations.
2.15 Dampers
The Efficient HVAC Control and Feedback System controls the flow of air
throughout the system with a series of dampers. These dampers are powered
typically with low 24 V AC electric motors. The dampers are referred to as doors
on the control process.
