The poet Friedrich Holderlin left a famous line: "Man lives in the world, achieves outstanding results, but still dwells poetically on the earth."
But this summer, the days of "roasting in the north and steaming in the south" make people anxious. In Beijing, where I live, the temperature frequently breaks through 40°C. It is no exaggeration to say that the air conditioner is responsible for my life. The latest report from the World Meteorological Organization shows that the El Niño phenomenon is currently in the early stages of development and is expected to lead to more extreme temperatures and marine heat waves in the second half of the year.
The hot weather has become more and more severe, and it has become a fuel for the growth of the air-conditioning market.
In some cities, it is also difficult to install air conditioners and require queuing. After finally installing the air conditioner, I accidentally encountered an "air conditioner assassin" with level 5 energy consumption. Facing the high electricity bill, I began to feel heartbroken. It is an "impossible triangle" to not only have high cooling efficiency, a good cooling experience, but also save energy and electricity. Today, Haier air conditioners have once again led the technological change in the industry through scientific and technological innovation to solve problems for users in order to allow users to enjoy the summer easily.
On July 19, Haier Air Conditioning and Xinhuanet jointly held a high-quality air-conditioning industry development forum and a press conference on variable shunt new technology with the theme of "green technology and low-carbon life". At the meeting, Haier Air Conditioning released the revolutionary green technology "Variable Split Flow", which has obtained the energy-saving and power-saving certification.
If you want to live poetically, you might as well find out how Haier air conditioners solve the "impossible triangle".
User has a question:
When can an air conditioner be economical and efficient?
To this day, air conditioners have not yet become a household appliance that is widely enjoyed by the public. One of the concerns that plague many people when using air conditioners is not the cost of equipment, but the "use cost" of high electricity bills caused by high energy consumption.
What everyone is waiting for is products that save money, low cost, and cool experience, so that we can truly live poetically in summer. However, in the "impossible triangle", the cooling efficiency and comfort experience of the air conditioner are mutually restrained. In the past forty years, the upper limit of the energy efficiency of the air conditioner has been firmly locked. To solve this problem, what is needed is a technological innovation that can change the industry.
Here it is necessary to understand the three technological revolutions in China's air-conditioning industry:
The first technological revolution was a subversive change in the form of air conditioners, from traditional window-type units to split-type air conditioners with low noise and higher performance.
The second technological revolution is the transformation of air-conditioning electronic control, from "fixed frequency" in which the compressor can only operate at a fixed speed to "inverter frequency", which can automatically adjust the operating speed of the compressor according to changes in indoor temperature to achieve a more comfortable effect.
The first two times were initiated by Haier Air Conditioning, and the third technological revolution is no exception. This year, Haier Air Conditioning launched the self-developed heat exchanger variable split technology, which revolutionized the air-conditioning and refrigeration system that has not had intergenerational technology for decades.
Traditional air-conditioning refrigeration adopts a single fixed flow path, which is equivalent to a fixed one-way lane. The flow mode of the refrigerant is single, which will affect the heat transfer characteristics of the refrigerant in the tube and reduce the cooling efficiency. Haier air conditioners have realized variable cooling and heating flow paths through the design and transformation of heat exchanger structures, and flexibly adjusted the number of branch circuits and pipeline layout, which is equivalent to variable lanes.
Masato Mori, a top expert at Nagoya University in Japan, commented, "This is an epoch-making technology."
It is not difficult to find that technological innovation is the key that everyone has been waiting for, which can unlock the "impossible triangle" and open the door to a new world.
Haier has a solution:
Synchronization of technological innovation and user needs
But here comes the problem again. Technological innovation relies on top-level research and development capabilities. Whether it can be implemented smoothly, at low cost, and with high reliability determines whether users can really use high-quality and cheap black technology. Otherwise, it is just a "high-altitude flower" in the laboratory.
In this regard, Haier Air Conditioning's technological productization capabilities over the years have realized the synchronization of technological end and user needs.
In every change of air-conditioning technology, Haier air-conditioning has appeared as a key leader, completed the landing of new technologies and new products, and continued to lead the industry forward, and this time is no exception.
For users, air-conditioning electricity bills are becoming one of the biggest burdens on public spending in summer. Saving money with real money is the last word for innovation. So, we might as well do the math directly.
The air conditioner really saves electricity, and the user can really save money. Once launched, Haier Refrigerant Inverter Air Conditioner won the "Energy Saving and Emission Reduction Science and Technology Progress Award" issued by China Energy Conservation Association.
Ten years ago, the energy efficiency of air conditioners for household appliances to the countryside was mostly level 5 energy efficiency. Compared with the energy efficiency level 5 of the current super-level 1 energy efficiency level, a single air conditioner can save 458 degrees of electricity per year, which can indeed save users a lot of money.
The industry is expected to:
Technology leads green, low-carbon and high-quality development
Under the background of the dual-carbon strategy, enterprises and society must actively take carbon-neutral actions to reduce their own energy costs and carbon emissions, and continue to achieve energy-saving and emission-reduction goals.
Once the variable shunt technology innovation and products are launched, it has also become a phased achievement of Haier Air Conditioning's efforts to develop green and low-carbon technology for buildings.
According to the Ministry of Ecology and Environment's "Notice on Doing a Good Job in the Reporting and Management of Greenhouse Gas Emissions of Power Generation Enterprises from 2023 to 2025", saving 1 kilowatt-hour of electricity = reducing the emission of 0.5703 kg of carbon dioxide. Taking Muhe, which has a strong carbon sequestration capacity, as a conservative conversion, every Haier refrigerant inverter air conditioner sold is equivalent to planting 20 trees every year. Based on an annual output of 8 million units, it is equivalent to planting 160 million trees.
Of course, the green and low-carbon air-conditioning industry cannot rely solely on the efforts of one company. Haier air-conditioning, as the industry leader, also plays a key role as an explorer and demonstrator.
On the one hand, Haier Air Conditioning "leads by example" and explores low-carbon standards. All seven factories have conducted carbon inventory according to international standards, and established the "China Inspection and Testing Society Room Air Conditioner Testing Green and Low-Carbon Laboratory". On the other hand, to accelerate the convergence of China's industrial forces in the cause of green energy conservation and environmental protection, lead and draft the "Carbon Neutral Technology Smart Home Appliance Low-Carbon Operation Evaluation Technical Specification Part 3: Room Air Conditioner" standard in 2022, pressing the accelerator key for the overall improvement of the air-conditioning industry's green and low-carbon level.
Break the "impossible triangle", bring a relaxed and comfortable summer to users, and return the beautiful green environment to the earth.
In the eyes of many people, the category of air conditioners has stabilized and the competition has become homogeneous. Is it possible to move forward? Haier's continuous breakthroughs in air conditioners are the best explanation and self-proof - as long as technological innovation and user needs are synchronized, there will always be new opportunities in the air conditioner industry.
This summer, because of technology, I live poetically.
