Indian summers have always been hot. Finally, the heat reaches the limits of human survival.area to tryApproaching.
If notworldThe country's most populous country has seen warmer temperatures across the country in recent weeks. Dozens of people at an event in Tsouboupass awayThousands of people rushed to hospitals with symptoms of heatstroke. hundreds of schoolsclosed schoolAnd the temperature continues to rise.
Fortunately, more immediate solutions, at least in the short term, are available. Demand for air conditioners has increased in markets such as India, China, Indonesia and the Philippines, where both incomes and temperatures are rising. According to one estimate, by the end of the 2020s, the number of air conditioners will increase by 1 billion units worldwide, and the market will grow almost at the same level as 40 years ago.duplicationis expected.
Air conditioning is good on a public scalehealthand economic activity, but it is certainly bad for the climate. A global agreement to phase out the most environmentally damaging refrigerants in air conditioning systems could put them out of reach for many who need them most.
The background of the air conditioner boom is simple. Economists say that family income is10.000 $(about 1.38 million yen), sales will skyrocket.
This level has recently been reached or will soon be reached in many of themworldwarmer places. The Philippines generally topped $10,000 in the past year, while Indonesia has caught up over the past decade. With more than 80% of the population still without access to air conditioning, India's GDP per capita purchasing power parity will reach USD 9,000 for the first time this year.
"Sales have increased more than 15 times in the last few years," said Kanwaljeet Jawa, who heads the India division of Daikin Industries.
Buying an air conditioner is a way out of poverty for both individuals and communities. The hottest countriesworldthey are often the poorest countries, but people in these countries tend to suffer from poor sleep quality and cognitive performance, which undermines productivity and performance. to be.
A study covering thousands of factories in India with different climatic conditionsTo seekshowed that productivity decreases by about 2% for every 1°C increase in temperature. This is a big problem for Indian Prime Minister Narendra Modi, who is seeking to boost exports and attract foreign companies. E. Somanathan, a professor of economics at the Indian Institute of Statistical Studies (ISI) in Delhi, who wrote the study, said heat-related losses over the past three decades amounted to about 1 percent of India's GDP, or about 32 billions of US dollars. there is a possibility.
But if climate change spreads too quickly, it could exacerbate the environmental problems facing the country. Most air conditioners use refrigerants that are said to be much more environmentally friendly than carbon dioxide. Countries with the fastest growing demand are still heavily dependent on coal power, and most people can barely afford the cheapest and least energy-efficient products.
Abbas Jar, a World Bank climate change specialist based in Singapore, says that if efficiency standards are not improved, "the planet will literally burn."
Countries with relatively rich and milder climates are tightening the rules for air conditioning systems, requiring greater energy efficiency and the use of environmentally friendly refrigerants. However, if such rules are implemented, the unit price will increase.InternationalClimate change agencies are pressing developing countries to cut carbon emissions, but their share of global emissions is lower than in countries such asUSA, where 9 out of 10 people have air conditioning. it is much smaller, India and others argue.
In the working-class neighborhoods of metropolitan Delhi, such arguments are abstract concepts, and for many people, whether or not they can benefit from air conditioning is a matter of survival.
Piyu Hardar, a 27-year-old domestic worker, said her humble home was like a fire in summer. The tin roof is hot enough to bake bread, and Haldar and her husband used to pour water on the bed before going to bed to cool the room.
A son was born at 16, but he had a fever because of the heat. That was already the limit. To get a lower price from Indian climate giant Voltas, Haldar stopped buying clothes, cut back on food, took out loans and doubled the number of houses he cleaned.
Hardar avoids using the air conditioner during the day, but turns it on at night and closes the door to keep the mosquitoes out and cool. In a windowless room decorated with teddy bears and toys, Yasir's son pressed his face to the air conditioner, rejoicing in the "cool breeze". “Relatives come to visit us just to sit next to us. They think our house has become too modern,” Haldar said.
As more people like Haldar buy air conditioners, manufacturers are trying to improve energy efficiency without crowding out their biggest growing markets with higher prices.
Godrej Appliances, one of India's largest retailers, said reducing the tax on air conditioners to 18% is a way to encourage people to buy better products. Currently, a tax of 28% is levied on luxury goods. "Air conditioning has become a necessity, not a luxury anymore," said Kamal Nandi, the company's general manager.
For manufacturers such as Daikin and Haier, regulatory plans to curb climate change could dampen growing demand for air conditioners. Part of this problem could be solved if countries adopted cleaner energy sources, but the refrigerant problem is more worrisome.
Hydrofluorocarbons, one of the representative refrigerants, are said to have 1,000 times the global warming effect of carbon dioxide. Scientists estimate that failure to drastically reduce our reliance on fluorocarbons could lead to half a degree of warming by the end of the century.
In 2016, more than 170 countries agreed to begin phase-downs in fluorocarbons from 2019, with a group of developed countries demanding reductions first. Soft drinks with a lower environmental impact from Chemours and HoneywellInternationalon the market, while Daikin and Mitsubishi Electric also have their own productsWe work.
"If you're not using eco-friendly refrigerants, you're a loser," said Jawa, managing director of Daikin's India division. The sector grew to $1 billion last year and is expected to double in three years.
Daikin's R32 refrigerant, which has about a third of the global warming potential of conventional refrigerants and is relatively cheap, is often used in household appliances sold by India's Godrej. But it's still slightly more flammable than traditional refrigerants and still very heavy, said Prima Madan, a refrigeration and energy efficiency expert at the US-based Natural Resources Defense Council (NRDC).
for gradual reduction of fluorocarbonsThe Kigali weddingthey are legally binding and although many of the targets are still in the distant future, developed countries are accelerating the pace of their achievement. For now, however, the alternatives are often expensive and even wealthier countries are struggling.
The challenge in India is to import cleaner productstechnologybefore millions of consumers buy new, greener air conditioners and use them for the next decade.
Last year, India experienced some of its hottest weeks since 1901. Severe heatwave with temperatures reaching 50 degrees Celsius across the Indian subcontinent. Hundreds of people died, power outages lasted for hours and even caused a spontaneous fire at a huge dump near the capital.
Naresh Tatabet, a driver from the Delhi metropolitan area, is someone who believes enough is enough. This month he bought his first air conditioner for his family. It's one of the biggest financial investments, he says, compared to buying a motorcycle.
No matter what happens in faraway Washington or Brussels, one thing is clear for Tatabet: she no longer wants to see her baby throw up in the heat. I'm sorry I woke up,” he said.

Why is air conditioning bad for global warming? ›
The more we run AC, the more electricity we use; more electricity releases more greenhouse gases, heating the planet and requiring even more AC to stay cool. “It's both a response to what is happening and also a driver,” says Renee Obringer, an energy researcher from Penn State University.How much of global warming is caused by air conditioning? ›
The researchers calculated air conditioning is responsible for the equivalent of 1,950 million tons of carbon dioxide released annually, or 3.94% of global greenhouse gas emissions.Why is the heat mode not working on my Fujitsu air conditioner? ›
Fujitsu Air Conditioner Heat Mode Not Working
In some cases, dirty filters, circuit breaker problems, or obstructed airflow are the reasons for this. If the settings are incorrect, set the AC unit to 'HEAT' and not 'Auto'. Next, look for the heating function and set the temperature higher than for cooling.
Most of the time, your heater releases cold air because the air filter is dirty. Every heating system has at least one air filter between the inlet and outlet ducts. When left unchecked, the filter will accumulate dust, fur, and other pollutants.Is air conditioning bad for the earth? ›
Because they use a large amount of energy, electricity production is increased, which emits more carbon dioxide into the atmosphere. At excessive levels, this greenhouse gas can trap heat near the planet's surface and contribute to global warming. Another factor is refrigerant.Is air conditioning a necessity? ›
Many more deaths have heat as a contributing factor but not the main cause. Keeping cool with an efficient air conditioner is the best means of preventing heat-related deaths and illnesses, according to the Centers for Disease Control and Prevention.What are the disadvantages of air conditioners to the environment? ›
Air conditioners affect global warming by emitting greenhouse gases that cause the earth to warm. These gases include carbon dioxide and methane. When the earth warms, ice caps will start to melt which will cause sea levels to rise.How did humans survive without air conditioning? ›

- Check your thermostat to be sure it's properly set.
If you're having trouble switching from heat mode to cool mode and vice versa, then there might be an issue with the reversing valve. The reversing valve is responsible for switching the heat pump from one mode to the other. It reverses the refrigerant flow and allows your heat pump to both heat and cool your home.Why heat pumps can't keep up with cold weather? ›
The reason that heat pumps tend to struggle in colder weather has to do with their method of heating. A heat pump is not a combustion based system. Instead of burning fuel, a heat pump will move heat from one area to another to heat a space. With most heat pumps, that heat has to come from outside.Why is my AC blowing cold but not too cold? ›
If your filter is dirty or clogged, your AC can't pull in as much air as it needs to per cycle. If your AC pulls in less air, it cools less air and pumps less cooled air throughout your home.Why is my AC blowing cold air outside and warm air inside? ›
It's either a dirty unit or a capacitor problem. If the unit is very dusty you need to clean out the dust to let it breathe. If the capacitor went bad, when you look at it the top will be bubbled up. Most likely it's the capacitor.Is air conditioning banned in Switzerland? ›
