Total number of air conditioners worldwide tripled by 2050 and global warming may accelerate

byTjflex2

Air conditioners indispensable for comfortable use of the hot summer consume electricity and emit greenhouse gases as they are used. The horrible cycle that the consumption of electricity increases by the use of the air conditioner and the greenhouse effect gas emitted by the power generation further increases the temperature of the earth and the air conditioner's use time increases more and more now is not only for developed countries but also for emerging countries It is spreading.

The World Wants Air - Conditioning. That Could Warm the World. - The New York Times

International Energy Agency (IEA)According to a report released by the report, the number of air conditioners in the whole world is about 1.6 billion units in 2016, but it is expected to increase to about 5.6 billion units by about 3 times in 2050. According to the report of IEA, it is expected that 10 air conditioners will be sold per second over the next 30 years.

Greenhouse gas emissions associated with power generation in 2016 was about 1,250 million tons, but in 2050 it is expected to increase to about 2.28 billion tons, nearly doubling. With the use of electric appliances, electricity consumption increases, the amount of greenhouse gas emissions associated with power generation increases, and the global warming of the earth further increases the demand for air conditioners.

Be an energy specialistFace Bior"About 90% of people living in the United States use air conditioners, but in extremely hot countries like Asia and Africa, Latin America and the Middle East, people who have air conditioners for a population of 2.8 billion people It is about 8%, "but in the future it is said that the rate of household air-conditioner installation will rise as incomes of emerging economies with low air conditioner holding rate increase. In cities such as Chennai and Mumbai in India, compared with Miami in the United States, the average temperature is twice as high as 24 degrees Celsius, and the number of days requiring air conditioning by air conditioners is very large.

As the income increases, the number of appliances installed at home increases, the IEA report points out that the room will become hot due to the heat released by those appliances, and the increase in income is related to the increase in demand for air conditioners . Moreover, it seems that it is said that "outside air temperature is rising by 1 degree in some cities due to use of air conditioner" in order to release hot air to outdoors instead of chilling indoors when using air conditioner.

The heat wave has an adverse effect on human health, the heat waves that hit Chicago in 1995 drove more than 700 people to death, and several tens of thousands died each time due to the rise in the temperature occurred in Europe in 2003 and Russia in 2010 Researchers are thinking. Introduction of air conditioner is necessary to avoid death due to abnormal heat, extreme thought that "do not use air conditioner to prevent global warming" can be said to be nonsense.

Researchers are proposing to increase the energy efficiency of air conditioners as a solution to global warming by air conditioners. Air conditioners sold in India consumes twice the power of air conditioners sold in the United States and China, and air conditioners sold in Japan and Europe are 25% more energy efficient than air conditioners in the US and China And that. Mr. Bior said the government should set standards for the energy efficiency of air conditioners and said, "Over the next few years air conditioners will continue to be a huge industry that occupies the second place among all industries, while at the same time, 21% is due to the demand for air conditioners, "he says. It is urgent to solve the problem of air conditioners to cope with global warming.
