Introduction of green technology
Green technology is a technology that provide us the clean energy and also helps
repair environmental damages or offers solution to wasteful practices. The green
technology is environmentally friendly, advanced and used in such a way so that it
doesn’t affect our environment and conserves natural resources. It uses renewable natural
resources that will not depletes easily, so it can also benefit our future generation. Green
technology contain various characteristic of technology which help us to reduce human
influence on the environment and create ways of sustainable development. Green
inventions are environmentally friendly invention that often involve energy efficient,
economic, social and environmental. Green technology uses different type of materials
such as non-toxic to produce thing. This technology can provide positive changes to us in
our daily life. By applying this green technology, our environment requires to recover
from pollution immediately. It helps to reduce pollution and improve the cleanliness of
our environment as well. Nowadays, many countries are changing to green technology to
protect the environment from negative impacts. By implementing green technology
wisely, our mother earth can be protected which reduces the negative impact of human
activities. It is important to protect our earth because when the earth is sick from
pollution, it will affecting on human’s health. Moreover, human being need to prepare
and participate in going green activity to make our mother earth become healthy again.
Human being should understand and aware the importance of green technology before
things become worst. There are various type of national green technology policy which
includes energy, environment, social and economy. To manage energy independence and
promote efficient utilization while the purpose for environment is used to conserve and
minimize the negative impact on the environment, energy can be used to implement it.
By using this technology, it can helps to improve the national economic development.
Besides that, to improve our quality of life, social can be used to implement it.

Effects of air conditioning system
Air conditioning plays an important role in our daily life. It provides us cool air to
cool down our interior’s air and to ensure we have a comfortable environment. During
hot summer season, the hot temperature is very high and air conditioning definitely is a
must equipment for us. It helps us to reduce the heat and humidity of our interior’s space.
It is important for us to stay and work in a comfortable environment because having a
comfortable environment will affect a person’s performance and mood. Besides that, air
conditioning will also help us to renew and improve the air quality of our house to ensure
us having clean air. Although air conditioning can provides us many benefits, but at the
same time it also brings many disadvantages to human being and our mother earth. Air
conditioning is the main contributor of causing global warming because turning on the air
conditioning will causes the release of carbon dioxide into the air and carbon dioxide is
the main element that will destroy our mother earth. Moreover, the increase of using air
conditioning will increase the production of greenhouse gases into the air. Due to the
global warming, air conditioning is also the one who is causing our environment to heat
up because when we are using the air conditioning, it will release the poisonous gas
which include chlorofluorocarbons and hydro-fluorocarbons into the air and causing our
environment become warmer and become not healthy. The continuous use of air
conditional not only will cause the happens of global warming but also leads harmful to
human health such as breathing problems, chronic headache, low blood pressure and so
on. It will become a serious problem if we did not take action about this concern.
Ways of air conditioning to enhance green technology
The air conditioning is one of the most important invention in our daily life. There
are many effects causes by using air conditioning. In this 21st centuries, technology is
very advance and it leads the scientist to come up with the creative idea of solution to
solve the problems of effect causing to the environment. There are some ways to reduce
the impact of uses air conditioning such as applying green technology. Many countries
already starting to use green technology in the industry. The main purpose of using green
4. 4 | P a g e
technology is to sustain the environment. Nowadays, propane is one of the popular
solution because many people are using propane gas for their residential energy needs
because it does not harm the environment. Propane gas consists of hydrocarbon and it is
produce from natural gas and oil refining which can makes it a clean gas. It is usually
used in domestic fridge and freezer and can be stored and used at anywhere. The
appliance that contain propane are more energy-efficient than those are using electricity
or natural gas. Besides, propane is more environmental friendly compared to others
because it produces less pollution like carbon monoxide and nitrogen oxide than the
electricity, this will helps to protect the environment by providing cleaner air and
effectively when compete with others fossil and fuel on efficiency. Propane has great
compatibility with materials usually used in the construction of refrigeration and air
conditioning tools. In addition, propane also able helps to cut discharges and protect the
environment.
Variable air volume systems (VAV) is also one of the method to improve the green
technology. Variable air volume is a sort of system using a large handler and central duct
system to control the capacity of a heating, ventilating and air conditioning system. A
variable air volume system permit its damper to open or close to allow the air to flow
through. VAV systems were created to be more energy efficient and to provide the
comfort for different heating and cooling needs on each building’s needs. It is
responsible to maintain suitable levels of comfort in air quality, temperature and moisture
level. A building that contains the similar heat gain and heat loss characteristics in a
small room or cluster room. The VAV system should be used in a larger buildings that
often needs cooling because the system can only provide one temperature of air. There
are different parts consists in this system which includes air handling unit, the supply of
ductwork system and the return of ductwork system. The VAV controller receives the
flow signal based on the different pressure from the pick-up device mounted in the duct.
The changes of pressure in the duct system may cause by the filters or effects from other
rooms are rewarded automatically to become a true pressure independent system. VAV
systems is an economical system because it works right around the levels of the cooling
loads. Besides that, it requires a low cost for installation in this system and it also reduce
5. 5 | P a g e
the system energy consumption cost. VAV system can control humidity in building zones
by separating the humidification and dehumidification equipment. Moreover, it has a
greater flexibility to varying loads which are easier zoned to control comfort and energy
saving.
Ice powered air conditioning is one of the company’s technology named Ice Bear
system. Ice bear turns the air conditioning into a more efficient appliances. It uses ice
batteries to cool buildings and helps to reduce a building’s total energy consumption.
Besides, it is compatible with 85% of all air conditioning unit. Ice bear is controls by
making ice during off-peak hours and releases by consuming the stored ice to cool
buildings during peak of the days. Ice bear system is a smart distributed energy storage
solution that work in combination with commercial direct expansion air conditioning
systems. The ice bear works by freezing 450 gallons of water in a tank at night and
making that offered for cooling the next day. It takes six hours for cooling when the ice
bear is switched its ice charging to ice cooling. This system usually deliver energy at
night when electricity generation is more efficient, cleaner and has lower cost, and
distributes the energy during peak hours to offer cooling to the building. Ice bear storage
consists of several benefits which can helps to reduce greenhouse gas emissions such as
carbon dioxide which could prevent early death. To allow the qualified HVAC
contractors can be trained easily to install and maintain the systems, ice bears can
produce significant commercial opportunities for local installers. The cost for ice
batteries is much cheaper than the lithium ion batteries. Furthermore, the ice storage
provides productive use of solar over generation, ice batteries can always work with solar
for the whole life. Both commercial and residential applications can be applied by ice
bear storage.
Next, chilled ceilings is a water-based cooling system which uses ceiling-based
radiant cooling panels joined with chilled water pipes or coils. It is usually used in those
building that requires energy use level below 50% in conventional buildings. It is vary
6. 6 | P a g e
from chilled beams because they will depends on radiant as different to convective
heating or cooling. The combination of natural convection and radiation can cools the
room by using the system. The main heat which is the radiation will transfer mechanism
for chilled ceilings. The “radiant chilled ceiling system” and “radiant ceiling panel
system” are also another named of this system. The chilled ceiling consists of a metal
sheet with water pipes running above it. One of the benefits using chilled ceiling can
helps to improve thermal because not only indoor air temperature can be controlled but
also mean radiant temperature, it will increase the satisfaction of human thermal comfort.
Thermal loads are satisfied because the comfort levels is better than those of other space-
conditioning. Moreover, it can helps to reduce maintenance cost because this system does
not contain fans or filters to maintain and it only require service like vacuuming of the
dry coil.
Inverter technology is refer to the changes of the compressor speeds to maintain
desire temperatures with minimal fluctuations. The inverter air conditioning is becoming
one of the popular technology in the HVAC field due to its environmental friendly and
provides energy savings. One of the common way to use the inverter is when the
incoming AC supply to DC voltage and then modify it by changing the voltage, current
and frequency of the power to the compressor. For example, the air conditioner with
inverter technology works like an accelerator in a car. When compressor requires more
power, it will provides it more power. When it requires less power, it will provides less
power. The compressor used in an air conditioning system is an ON or OFF type, it is
works either at the maximum capacity or none at all. For this technology, it uses more
power or less power will only depends on the temperature of the incoming air and based
on the level set in the thermoset. This technology was established in Japan and it is being
used effectively for air conditioners and refrigerators. In this system, the only appliances
that can be used is spilt air conditioning. One of the most important factors is energy
savings because the benefit balances the initial cost in the long run. This technology can
reduce the uses of energy compared to the traditional system. In addition, the compressor
can run full speed to provide fast cooling to the room during start up. The fluctuation of
temperature is minimum compared to the ON/OFF type of compressor. It provides a
comfortable environment for the residents all the times. Another benefits that inverter
7. 7 | P a g e
technology can provides is quiet operation. The external unit of the converter compressor
is much more silent than the non-inverter compressor.
Lastly, the problems of air pollution is getting very serious nowadays. We should
stop all the actions that are destroying our environment. Our mother earth is very
important to us because we only have one planet to live on. Our mother earth can live
without us, but we cannot live without our mother earth. Human beings have the
responsible to protect and conserve our nature environment. We have to save our mother
earth for ourselves and also for our future generation. We should appreciate and blessed
that the air we breathe for us to live in our daily life. We should take good care of the
beautiful trees that give us oxygen to breathe. At the same time, we should take action to
protect our environment. For example, we should prefer green technology instead of
using the technology that brings negative impact to our environment. I believe that every
of us makes a little changes, we still can make this planet to become a beautiful place.
