How Does Global Warming Occur?
The Earth maintains a balance of heat: in the daytime, heat from the sun warms the planet, while at night this heat is emitted back out of the Earth’s atmosphere. But if greenhouse gases like CO2 increase, heat is trapped and the Earth’s surface temperature rises. This is the global warming phenomenon.
The sun’s heat escapes back into space after warming the earth, thus maintaining an atmospheric temperature ideal for life. The greenhouse effect causes the temperature to rise. CO2 and other greenhouse gases. Greenhouse gases in the atmosphere increase.
How Does Ozone Layer Depletion Occur?
The stratospheric ozone layer above the Earth’s atmosphere protects us by absorbing the sun’s harmful ultraviolet (UV) rays. However, a little more than 20 years ago, it was discovered that the ozone layer above the Antarctic had become thin. Scientists pointed out that this was the result of the ozone layer being broken down by CFCs (designated fluorocarbons) used as refrigerants in air-conditioners and refrigerators.
To prevent refrigerants from entering the atmosphere, Daikin takes great care to ensure that air-conditioners and refrigerators that have reached the end of their useful life are properly handled by retail outlets.
What Should Air-conditioners Do for the Environment?
There are two main ways that air-conditioners impact the environment in a life cycle that includes manufacture, use by customer, recovery, and disposal at the end of useful life.
Air-conditioners need electricity to operate, and power plants generate CO2 (carbon dioxide) through the process of power generation. This is one of the cause of global warming.
Air-conditioners use fluorocarbons as refrigerants. Fluorocarbons affect the ozone layer and contribute to global warming. In addition to the above, there are other things that must be done: making efficient use of the resources used as raw materials for air-conditioners; and properly disposing or recycling used air-conditioners.
