Automobile air conditioning is use to cool the occupants of the car in hot weather reducing the temperature of the cabin to a reasonable level. This system is associated with increased fuel combustion within the vehicle by about 20%. The transfer of heat process takes place inside automobile air conditioning by the aid of refrigerant substance that carries out the "transfer of heat process" by cycling through the air conditioning system and absorbing heat after being in the gas state and giving off it in the liquid phase. In the United States, vehicles are the major factor contributing to about one third of all U.S air pollution. Automobile result in increased vehicle exhaust emission that affect local air quality and CO2 (greenhouse gases). …show more content…
When these chemicals are released in the atmosphere during the heat transfer process, the ultraviolet rays break its molecules releasing chlorine atoms which attach to the upper ozone protective layer destroying it. The net result is that more U.V rays reaching the earth s surface with the resultant bad effect both on health and environment. The health hazards include increased percentage of people affected by cataracts and skin cancer. According to the US Environmental Protection Agency, the degradation of the ozone layer will cause 12 million people to develop skin cancer within the next 50 years. Significantly, more than 200,000 of those cases will be fatal. Also, ozone depletion will result in compromised the human immune system. On the other hand, agriculture and animal and plant life will be …show more content…
On the other hand, automobile owners should not ignore any defect or damage in the conditioning system and repair it as soon as possible. Also, automobile service technicians should be well qualified and certified for proper work. Additional control of environmental cost of automobile air-conditioning can be made by designing new vehicles that need less cooling thus lowering the amount of fuel used and emissions of the refrigerant substances used for cooling. Also, developing new air-conditioning technology by designing new systems with high cooling Performance and reliability, operational and service
Stratospheric ozone absorbs 97-99% of ultraviolet radiation. As this protective layer continues to dissentigrate, human health will suffer. One American dies every hour from skin cancer, a direct result of ozone depletion by anthropogenic chemicals, primarily CFCs, which damage the ozone layer. Alternate chemicals are now being used in the place of CFCs that will not damage statospheric ozone, and there is international recognition of the importance of developing these chemicals. The Montreal Protocol is an international treaty which limits the production of ozone depleting substances. Still, human health is at risk from the deletion of ozone, and the risk factor will continue to rise unless people and industries become more aware of the implications connected with everyday use of chemicals which destroy stratospheric ozone.
For the times in life where the automobile doesn’t work like it use to before. This is the person behind keeping the automobiles in top shape so in any weather, and always making them start under any condition other than if the gas tank was empty. The automotive technician is needed for society because this person corrects one’s automobile problems in all shapes and sizes; he or she performs regular maintenance, major engine repair, and other unnoticable problems not seen to the naked eye.
Inventers are trying their best to lower the chances of our global climate changing so much. Every year 15 million gas powered cars are sold around the world. When people use gasoline powered cars, the fumes from the exhausts rises into Earth’s atmosphere and helps destroy our ozone layer. The ozone layer helps keep UV rays from beating directly on our skin. The ozone has a cavity or small hole appearing in the middle of it, which mean it can’t block UV rays. Fumes from the car play a huge part in this catastrophe. While the hole gradually increases, more heat is allowed into our atmosphere which makes Earth’s temperature rise. To solve this predicament we can stop using gasoline and diesel powered vehicles. Electric cars can eliminate this huge issue with our planet and its
The depletion of the ozone layer has been a trending topic after it was first discovered in 1970. The ozone layer is a portion of the earth’s stratosphere which absorbs most of the sun’s UV rays hence preventing cancer and other fatal illness to the skin. It contains high concentrations of O3 and at a constant rate is being broken down and. Since 1970, it has been discovered that about 4% of the ozone layer wears off every decade and is as a result of day-to-day human activity.
Along with being aware about air pollution, we should also be aware about ozone concentrations and fossil fuel burning. The public should be concerned with ozone concentrations because they are constantly increasing. Ozone levels are increasing because of the heat and pollution. The public should be informed on how to reduce pollution and heat. Some steps the public can take to reduce pollution are to use public transportation and electric vehicles, conserve energy and recycle. Moreover, planting more plants will reduce heat and decrease ozone levels. Ozone is considered “bad” when found in the lower troposphere because it leads to many health effects in humans. Breathing ozone can cause bronchitis, emphysema, and asthma. Therefore, humans should stay indoors in the afternoon during the summer months. “Bad” Ozone also damages our crops and forests, affecting our food chain and the economy. Ozone is considered “good” in the Stratosphere because it protects us from dangerous ultraviolet rays released by the sun. Ozone in the Stratospheres protects us from conditions such as skin cancer and cataracts. Furthermore, ozone in the atmosphere protects our crops, thus playing
A thin layer of gas called atmosphere surrounds the Earth. The atmosphere serves two important purposes: it is a filter for the suns dangerous ultraviolet radiation rays and keeps the heat, necessary to maintain life on earth, within the stratosphere (Vorlat 361). Ultraviolet light is incredibly dangerous to all the organisms within the Earth's ecosystem because it causes skin cancer, effects the immune system, and harms plant and animal life. For that reason the atmosphere and the ozone layer within it are crucial to a stable life on this planet. The ozone layer is in danger, however. It is facing depletion by a toxic man-made substance called chlorofluorocarbons (CFCs). Together the international community is working through treaties and conventions to stop this environmental problem.
The increase in air conditioning usage will also increase the amount of heat released into the atmosphere, this will also contribute to air pollution, as more greenhouse gas emissions are being released. This negatively impacts air quality which can result in an increase of urban smog.
If progress is made toward making cars and trucks continuously more and more environmentally friendly, then the biggest source of harmful emission into the atmosphere will be put to a stop. On average, for each mile driven in a standard vehicle, 411 grams of carbon dioxide are emitted into the atmosphere, this equates to roughly 4.7 metric tons of carbon dioxide per year, whereas a car that operates fully on electricity releases no tailpipe emissions into the atmosphere(EPA, 1). As this staggering
Ozone depletion directly affects society and the environment through increased exposure to UV radiation on humans, animals, plants and materials.
As the ozone layer continues to be depleted, more harmful ultraviolet rays are able to penetrate the earth's atmosphere and are absorbed by its surface. Although the sun's emissions of UV rays remain constant, decreases in stratospheric ozone levels cause a reduction in the Earth's protection from the sun's harmful rays. Research has recently shown that over exposure to UV-B radiation can impair the body's ability to fight off disease, in addition to causing skin cancer and a range of eye disorders. Ultraviolet radiation also deleteriously affects plant growth by reducing leaf size and the...
Many hazardous pollutants escape from the internal combustion of the engine. Conventional gas powered vehicles use irreplaceable fossil fuels to run. When burned, these fossil fuels create numerous toxins like carbon dioxide (Larminie 246). Carbon dioxide is considered the main greenhouse gas that creates the foundation for global warming (hybridcars.com, pollutants). This harmful pollutant may not have a serious effect on people at first, but it does have consequential effects on the environment that in turn put people in danger (Nutramed.com). The major consequence caused by global warming is the rise in average temperature. This results in a domino...
A notable automotive manufacturer had asked Heliotrope Enterprises to conduct a detailed research on hybrid electric vehicles in terms of cost effectiveness, affordability and environmental issues. The main purpose of this research was to recommend a vehicle which is not only fuel efficient but also partially or fully dependent on electricity as compared to the conventional cars. The hybrid electric vehicle is the new generation car which works partially on electric battery and partially on the conventional combustion engine.
Climate change has been one of the most discussed issues in these modern days. It is prove on many researches that the increase in man-made green house gas emission can significantly affect the climate in the world, on every part of the globe. In the last few years, climate change has become the most researched subject in science. The reason is that because climate change can affect significantly to the earth and it has to be taken care of. In a business world, particularly in Automotive Industry, climate change is also one of the must discussed subject, and because of automobile is one of the factors that produce the most CO2 (Carbon dioxide), it become one issue that force automotive industry to change their product to reduce the amount of CO2 emission.
Car pollutants cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, causing global warming, acid rain, and harming the environment and human health. Engine noise and fuel spills also cause pollution. Cars, trucks and other forms of transportation are the single largest contributor to air pollution in the United States, but car owners can reduce their vehicle's effects on the environment. Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
Both of the two auto vehicles are brought into the human industry as the use of benefit students’ lives become more convenient traveler. In commons, the two automobile created opportunities jobs in the economic companies’ nation. Plus, several students did not noticed that both cars and public transportation have one major similar concept where two of the transit vehicle produce environmental pollution, traffic congestion, and oil consumption problems. Encounter, the public transportation and cars can cause a huge impact to the environmental which it can lead human health problems. Mostly, both of the automobile still release noxious gases into the air, and over time the built up can change the environment global warming to like an unhealthy
