At 10 o'clock in the morning on April 7, the atmosphere of the new conference room W201 was warm and the halls of more than 200 people were packed. The theme forum of the 21st Refrigeration Exhibition was held here.
Several experts attending the conference were called “heavyweight” by Wu Desheng, the forum host and deputy chairman of the China Refrigeration Association, and they also made serious preparations. Including Xu Tingming, the counselor of the State Department who has not yet come to the forum due to official business, he also printed multiple copies of his report "Technology and Low Carbon" and put it in the conference hall for everyone to read.
The report of Wu Jisong, a foreign academician of the Royal Swedish Academy of Sciences, started from his familiar and controlled thermonuclear fusion and peaceful use of hydrogen, interspersed his own experience at home and abroad, and analyzed the current national low-carbon policy with interesting and lively language. He said that with the current consumption rate, the world’s oil will be exhausted after 45 years. If we do not change the development mode, then each household’s car will become the sedan chair of the Qing government official. It can only be a decoration. . Low-carbon development is actually a compelling development. Carbon is the source of resource depletion, environmental pollution, and ecological deterioration. From carbon to low carbon, carbon-free and carbon-free cycles tend to be inevitable.
As the first person in China’s knowledge economy, Dr. Wu summarized the source of low-carbon development as a new economic theory. He explained the theory and practice system of the new economic concept in detail through the chart. This theory is specifically the 5R theory of Rethink, Reduce, Reuse, Recycle, and Repair. Such as reduction is the formation of reasonable demand, the establishment of new values ​​in harmony with nature; reuse is the full use of renewable resources, the establishment of optimal allocation of new resources concept; recycling is an economic system from the production of extensive open chain into Closed-loop intensive, the establishment of a new industry concept of the ecological industry cycle.
“We often say that independent innovation, from the perspective of air-conditioning and refrigeration industry, I think that innovation should first of all be a big system and ideological innovation, rather than entangled in the local whip. Open a new path is to crack the Achilles chase The only way Turtle said it,” said Professor Jiang Yi of the Tsinghua University Building Energy Conservation Center at the theme forum.
As the only academician of the Chinese Academy of Engineering in the refrigeration industry, Jiang Yi's report directly cuts the topic—the thinking on the future development of air-conditioning and refrigeration. It covers the status quo and market demand of air conditioning and refrigeration systems; the major problems faced by air conditioning and refrigeration systems; possible solutions and core key technologies to be solved. Although there is no direct low-carbon idea, energy conservation and consumption reduction go through the beginning and end of his speech.
Jiang Yi pointed out that there are many problems in the current air conditioning and refrigeration systems in terms of condensation and dehumidification, system structural systems, elimination of heat and moisture losses, transmission and distribution forms, end forms, and delivery of fresh air. Our main task is to significantly reduce energy consumption and costs through technological innovation, achieve China's creation, and lead the global market. In the future, the development direction of air conditioning and refrigeration is based on the different heat load characteristics of different functional building spaces, and the operation of different needs; according to the actual needs of different uses different characteristics of different forms of air conditioning refrigeration. For example, civil buildings and industrial buildings have completely different requirements for refrigeration. In terms of civil buildings, we need the unification of winter and summer, high-temperature cooling, and low-temperature heating; the air-conditioning system with independent control of temperature and humidity; and at the same time, reduce the energy consumption of transmission and distribution systems. Focus on the unified disperse phase, fully guarantee the supply of fresh air and the use of effective fresh air.
Mr. Didier Coulomb, Director-General of the International Refrigeration Institute, concluded his report entitled "The Copenhagen Conference and our Low-Carbon Responsibility." He pointed out that refrigeration has been indispensable in people's lives and has been widely used in food, health and energy. So it has some impact on the environment. In the future, mankind will face many challenges from the energy side, and the ecological and environmental issues are imminent. He also briefed everyone on the situation of the Copenhagen conference and called on everyone to do their part for low-carbon development.

N95/KN95 Mask Machine

HTD is a professional machinery manufacturer with more than 15 years. Since its establishment, we have been adhering to the core of user needs, and have been providing stable quality equipment, raw materials, and thoughtful after-sales service to customers in more than 30 countries and regions around the world, winning the trust of customers and praise from many companies.
Our main products are:fully automatic medical Mask machine,fully automatic 2D folding mask machine like KN95 mask making machine and N95 mask making machine,3D mask making machine like the fully automatic Cup Mask Machine,disposable 3ply flat face mak machine,KF94 fish type mask making machine and others non-woven fabrics products and raw materials,spare parts and so on.


The fully automatic KN95 N95 folding face mask making machine is a fully automatic machine for producing folding mask production lines. It uses ultrasonic technology to fuse 3 to 6 layers of PP non-woven fabrics, activated carbon and filter materials, non-woven fabrics, ear bands, printing, half-folding, edge-sealing, and roll cutting. It can also process 3M 9001, 9002 and other folding masks. Depending on the raw materials used, the produced masks can reach different standards such as FFP1, FFP2, N95, etc., without manual operation, all are produced by mechanization.
This machine is an all-in-one machine of automatic three-dimensional folding mask. From the feeding of cloth to the completion of automation of finished products, including (upper bridge strip, printing), spot welding of elastic belt, folding, forming, welding and cutting of finished products, waste removal, and finished product output, the automatic production on a machine is fully realized. (The whole machine only needs one person to operate).


Through our unremitting efforts and continuous research and development, we provide customers with labor-saving, efficient and stable automated production equipment,We offer free consulting, can strongly supply the mask materials and machine efficient after-sales service in One-stop service.All of our products have CE and test reports.
