Household air conditioners have always been "large energy consumption" and the focus of low-carbon development in the refrigeration industry. How to reduce air conditioning and cooling industry gas emissions through refrigeration technologies.

Recently, at the award ceremony of the Global Refrigeration Technology Innovation Grand Prix, industry experts have said that as the world's largest household air conditioning market and household air conditioning, the development and application of breakthrough refrigeration technology, the strong support of policy, low carbon for my country's refrigeration industry It is especially important.

Removal reduction of reduced pressure reduction

According to International Energy Agency, by 2050, the global household air conditioner or more than 4.5 billion units, energy consumption will exceed 10% of the total global energy consumption. At that time, my country's home air conditioning stock will also reach 1 billion units.

"The global socio-economic development and gas warming promotes people's demand for comfort-free air conditioning. At present, the air-conditioning electricity load in large and medium-sized cities in the world, accounting for 40% -60% of summer peak load, and the amount of electricity consumption brought by air conditioning And greenhouse gas growth is one of the major challenges of global. "Academician of the Chinese Academy of Engineering, the director of the China Refrigeration Society said.

International Energy Transformation Energy Policy - Heating and Refrigeration and Refrigeration of Energy Transitional Era, "Heating and Refrigeration Accidents account for approximately half of global energy consumption, and most of these energy is inefficient from fossil fuel or biomass energy. Utilization, its carbon displacement accounts for more than 40% of global energy carbon emissions. Therefore, the development of efficient heating and refrigeration technology has become a matter of priority to countries. "

It is understood that my country's refrigeration energy consumption is still facing the total amount of high and high growth, especially in the need to solve the climate impact of household air conditioning refrigeration.

It is worth noting that on April 16, my country announced that "the" Montreal Protocol "will enhance the control of non - carbon dioxide vapor vat gases such as hydrofluorocarbides. Hydrofluorocarbides are just refrigerants commonly used in refrigeration industries. Jiang Zi believes that this is a higher demand for my country's refrigeration industry, and it also brings huge opportunities for the green development of the industry.

Some air conditioner refrigeration efficiency is less than 20%

Liu Yanya, former deputy director of the Ministry of National Climate Change, Department of Science and Technology, believes that it should deal with the change of gas and carbon peaks, carbon neutralization goals, which depends to a large extent on the improvement of science and technology, especially the breakthroughs of core technology, and standards Level improvement. my country's energy consumption and carbon dioxide emissions, electricity, industrial, architecture and transportation are inseparable from refrigeration technology and equipment. According to estimates, global refrigeration accounts for about 10% of global electricity. The advancement of refrigeration technology is significant for energy saving.

"There is currently 20% of domestic air-conditioning products in the market, and the potential of theoretical upper limit is less than 20%, compared to LED, solar photovoltaic, etc.," Jiang Zi believes that my country is produced as the world's largest refrigeration products. , Consumption and exporting countries, with the largest scientific and technological personnel in this area, should lead the role in technological innovation.

The "Air Conditioning Additional Function Development Status and the Influence of Air Conditioning Additional Function" issued by Natural Resources Protection Association and China Standardization Research Institute show that additional function of different types of air conditioners is different. Therefore, encouraging development and promotion of significant improvement of performance, efficiency, which helps further increase air conditioning energy efficiency.

Support policy needs to be strengthened

"The carbon peak, carbon neutralization target is clear, accelerated the process of carbon emission reduction in my country. For air conditioning refrigeration industries, main research directions include low GWP refrigerant replacement, reduce actual emissions and improve equipment energy efficiency, these three aspects It is also an important challenge for the air-conditioning refrigeration field in the next period of time. "Said Wang Baolong, a professor of the Department of Architecture Science, Tsinghua University.

"Emissions in the refrigeration industry come from the use of electricity, carbon dioxide emissions from the production process, and on the other hand, from the discharge of non-carbon dioxide greenhouse gas such as refrigerant." Wang Baolong believes that the refrigeration industry should be adjusted by internal energy structure through the industry. And add the scale of cleaning energy to reduce emissions. "For example, optimized use can be elastic, improve renewable power usage; reduce refrigerant disclosure, promote recovery, regeneration and reuse of refrigerant, and do refrigerant alternatives."

In the view of the chief engineer of Huashang International Engineering Co., Ltd., the refrigeration industry is in deep participation in carbon reduction, but also increases policy support. "It is recommended to include the refrigeration industry into the scope of carbon emissions transaction. At the same time, through tax, credit, safety supervision, environmental protection and other policies form a joint force, jointly promote the process of carbon reduction."

Dong Mingzhu, Chairman and President of Zhuhai Gree Electric Co., Ltd. expressed similar views. She said that the state should speed up the standard and technical specifications of "zero-carbon development" in the refrigeration industry to promote the progress of the industry.
