如果中国不加快空调企业降低成本，提高材料的替代技术，竞争和外国投资将处于不利地位。

空调在国内推广铝代铜的技术和产品的上游厂商熟悉：青岛海青机械厂业务，以堵塞电阻压力焊接技术，生产铜，铝连接管说，浙江新龙实业的在今年年初召开的“全铝空调热交换器”，“分体式空调（铝）连接管”省级新产品的省级鉴定;江苏兴荣高科技公司的独立研究和发展铜铝复合管（行政控制），一铜和铝之间的冶金结合的成功实施;浙江闳厶嗯管道替代品。目前，经过空气中的产品的三家公司，空调行业还处于试验期推广还没有实现大批量生产和商业化应用的铜，铝连接管清已达到满负荷生产，目前占用超过20年的连接管％的市场份额。

今年年初，浙江新龙控股于2002年自行申请的“分体式空调器连接管的实用新型专利”，控方称，铜和铝的南方管道准备使用一空调生产企业（江苏清企业的生产焊接技术模仿），要求赔偿费大量的公司。

“不提案件本身，非铜，铝连接管和空调专营权是最终的，因为压力电阻焊接技术包含了30几个专利是在青岛海青和中国海洋大学手里，所以清与企业共同被告。这项诉讼的真正目的是针对企业超过100万台订单的竞争。“材料研究所的中国海洋大学，高级工程师赵吁屙说：”这是从上明显关于知识产权的名义另一方面，铝铜市场报告中已变得日益重要。“

专利金

代铜与铝的空气现实问题空调技术是如此的关注，其背景是近年来国际铜的价格迅速上涨，从每吨2万吨左右，上升到800万元，目前价格仍高，有6万吨左右。对于一个半空调为例，按照现有的技术需要使用6-7公斤左右，空调成本将直接达到约200-250元铜。 （包括管防腐蚀材料）价格是相同规格的铜价格3 / 10，空调行业以铝代替铜，将有效地降低成本，空气调节业务。 “特别是明年，提高能源效率标准，每个企业都面临着如何降低成本的问题，材料替代，企业不认为是最现实的解决办法。”赵说。
在今年的全国知识产权大会，海青的“薄壁铝合金管的焊接技术”荣获“第十届中国专利金奖，”这项技术的发明人开始
是，赵钺海青机械厂厂长，高级工程师左铁。该技术使内部和外部之间的航空网络连接，空调，以减少一半管成本，使每一个空调生产空调公司空调可以节省一电解铜1公斤。 “直到现在，海清有十多个国内和国际合作的空调制造商，清以铝，铜技术节省了国家的1.5万吨铜资源，为100元人民币的每个值用黄铜铜连接后，才管成本30-50元，节省了至少百分之五十的费用。“赵启正说。

左铁赵吁峨合作被称为工业界，学术界，研究合作，实现就地典型科研产业化。我离开铁在山东省的焊接研究所副所长，他介绍，从知识的不同特点，铜，铝：铜的密度，可扩展性和空气连接的两端，内部和外部的机器只能用空调铜，以确保密封性和压缩，而中间部分的管道，以确保只扮演流的作用，所以只要对铜，铝连接问题的解决，对铝铜场所使用没有问题。左铁军说，30多项专利清电阻压力焊接方法，焊接实现无脆性组织铝，铜，铝原子结合，焊缝非常强大，无论是拉伸，弯曲，压扁不是会有任何的差距。 “直到现在，海清率先向市场推出已在第一个五年。但至今没有任何问题，投诉的质量。按照一般标准的企业按照规定黄铜故障率低于1.6出色的产品，他和清作为一个0.1的失败率。“

，但是，离开的感觉钢铁赵吁锇不幸的是，与去年相比，国内空调企业使用铜铝管没有增加的总额，这意味着，国内空调在今年铝铜的应用仍处于停滞状态的企业代表。 “原因是去年发生的与空调之间的斗争，铜和铝业务，战争的话。”左铁说。

一项营销计划代表后遗症

铜铝如家喻户晓的技术上游，但也“感谢”美国去年，策划营销活动。

介绍，据知情人士透露，去年上半年，美国一直在精心策划，在大型空调店举行了“永结铜”的活动，而且还专门在“铜印”和“铜铝连接管“的优势和比较表，铜缺点铝连接在”密度管指示，质地柔软，预期寿命短，制冷效果差，压缩弱，容易导致破灭“的三大处于不利地位。促销员美容，甚至直接向终端铝管的“黑心管”之称。

直接引起了7月美国与规划去年空调行业，铜，铝约占口水战管，虽然当时包括中国家电协会，其中包括一些权威机构站起来对支持基地代表铜技术，但争论还没有完全解决，消费者的认知错误，所以很多消费者代铜这一新技术的铝有排斥的态度。此外，铜，铝连接管的国家标准尚未实施，导致空气中多空调企业放慢了步伐，铝铜替代。

据了解，铜，铝管，海信科龙在去年7月举行的记者招待会上，有高的代表科龙空调高调宣布空调铝铜连接从原来的3年保修期管道至10年。但今年，海信的铜，铝管材科龙刻意保持低调。虽然海尔清今年发行超过百万的铜，铝管套订单，但也只是工作的努力，并没有公开支持铝代铜技术。格力和志高，更是减少的订单数量。

格力现在在美国“声称，产品的国内销售无用的铜和铝管，每个包含两个。最近，媒体打破了美国，也悄悄地增加了铜，铝管材的数额，但在表面上不愿公开承认，一个营销计划，使空调企业对保密这一新技术，大企业对行业的影响可以看出。“左铁毫不感情不是。

等待格力

美丽留在按照铁军提供的数字，去年海青许可证，铜和铝的空调连接管超过400万台，今年的销量，完成了600多万套。这包括美国超过100万台的订单业务，韩国，日本，巴西，印度。 “这意味着，国内空调企业使用铜铝管总量没有增加的基本。”

“到目前为止，格力和美国是唯一的出口产品使用铜和铝管。”但左铁认为：“国内空调企业迟早会认识到这一技术。”

铁军留下的帐目计算的：假设美国家庭格力分体空调，供10万台，空气一套与铜和铝生产空调管空调节省50美元的平均，则节省的费用每年为500亿美元。 “要知道，空气已进入低利润时代，一年的净利润是五六亿元，为他管我这么多的省份，他是没有理由不”！左铁

另一个原因是，今年，美国，韩国，日本，巴西，印度和其他国家开始频繁空调巨头送到清检查，逐步提高铜，铝管材的订单，只有大空调企业在韩国明年订单将超过100万套。也在测试明年有相关产品的国内子公司将是采购量几十万套，“如果中国不加快空调业务，以降低成本和材料替代技术，是在不久的可能在未来的外国竞争中处于不利地位。“铁去了，并非没有隐忧。

“虽然以一铜的各种技术的混合代表铝行业，该行业有一个清洗的问题，虽然铜，铝管材只设有带空调铜1 / 6，空调业，大幅降低成本还取决于散热器，开关铜替代，但铝代铜铜资源无疑代表了时代枯竭的空中发展方向调节行业，我们的任务是首先要建立这个市场。“左铁说。

空调行业资深观察家认为

张彦斌国家标准颁布

可以摆脱资源的障碍，铝铜替代的稀缺资源范围广泛，有空调的发展史技术革命。 “铝代铜”，一个简单的外观不仅降低了成本，但好处是深度了解当代，在长期的技术进步功能的空调产品的青睐，进一步代表的农村市场渗透34。

空调行业是铜的消费，在空调行业，以促进“基地代铜具有重要意义”，但现实是，空调行业开展“基地代铜”是仍处于初期阶段，远离其他消费铜大—汽车业的更快的替代方案。事实上，空调的“基地业务代铜工业”，可促进一刀切非常期待，毕竟这是一个技术进步，可以减轻日益增加的成本压力。然而，在真实环境中市场因素迫使只是谨慎的空调制造商。我们都在等待机会，如果一个国家颁布的标准，市场推广介绍了将无后顾之忧。市场上的介绍，是国家标准的办法，打破障碍之一。

GB missing aluminum substituting copper air-conditioning very difficult

if China does not speed up the air-conditioning businesses reduce costs and enhance the material substitution technologies, competition and foreign investment will be at a disadvantage.

air-conditioning business on the domestic promotion of aluminum-generation technologies and products of copper upstream manufacturers familiar: Qingdao Haiqing Machinery Plant to plug resistance pressure welding technology to produce copper and aluminum pipe to connect the said; Zhejiang New Dragon Industrial in the beginning of the year the convening of the “all-aluminum air-conditioning heat exchangers,” “split-type air conditioner (aluminum) to connect pipe” provincial-level appraisal of new products; Jiang苏兴荣high-tech company independent research and development of copper-aluminum composite pipe (ACC control), the successful implementation of a metallurgical bond between copper and aluminum; Zhejiang Hong Sing a pipe alternatives. At present, after the three companies of the products in the air-conditioning industry is still in the promotion of the trial period has yet to realize large-scale mass production and commercialization of applications of copper-aluminum connecting pipe Haiqing has achieved full production, currently occupy more than 20% of the connecting pipe market share.

the beginning of this year, Zhejiang Xinlong holding their own in 2002 to apply for the “split-type air conditioner connecting pipe” of the utility model patent, the prosecution claimed that the use of copper and aluminum pipe preparation of the South in a air-conditioning manufacturing enterprises (from Jiangsu Haiqing imitation of an enterprise production welding technology), require the companies huge amounts of royalty compensation.

“not to mention the case itself, the non-copper-aluminum connecting pipe and air conditioning franchises are in the end, because the pressure resistance welding technology contains 30 Several patents are in Qingdao Haiqing and Ocean University of China hands, so Haiqing the enterprise together with the respondent. The real purpose of this lawsuit is against the business for more than one million sets of competing for orders. “Materials Research Institute Ocean University of China, Senior Engineer Zhao Yue said,” This is evident from the On the other hand note on behalf of intellectual property rights in the aluminum copper market has become increasingly important. “

patent gold

trouble with reality substituting copper aluminum air-conditioning technology is so concern, and its background are In recent years the international price of copper rose rapidly, from 20,000 yuan per ton per ton rose to 8 million yuan, now the price is still high 6 million yuan per ton. To a semi-air-conditioning as an example, in accordance with the existing technology required to use copper in about 6-7 kg, air-conditioning costs will be directly up to about 200-250 yuan. And tubes (including anti-corrosion materials) price is the price of the same specifications brass 3 / 10, air-conditioning industry to replace aluminum copper, will effectively reduce the cost of air-conditioning business. “Especially next year, improve energy efficiency standards, each enterprise are faced with the problem of how to reduce costs, materials alternative enterprises are not considered the most realistic solution.” Zhao said.

in the beginning of this year’s national Intellectual Property Conference, Haiqing’s “thin-walled aluminum pipe welding technology” won “the Tenth China Patent Gold,” the inventor of this technology is that Zhao Yue and Haiqing Machinery Factory director, senior engineer left Iron. This technology enables connectivity between internal and external air-conditioning to reduce the cost of pipe in half, so that every production of air-conditioning companies air conditioners can save one electrolytic copper 1 kg. “Until now, Haiqing has more than a dozen domestic and international co-operation of the air-conditioning manufacturers, Haiqing substituting aluminum for copper technology has saved the country 15,000 tons of copper resources, the value of 100 yuan each of the brass used Copper connecting tube only after the cost 30-50 yuan, saving the cost of at least 50 percent. “Zhao said.

left Iron and Zhao Yue cooperation be called industry, academia, research cooperation, realize the industrialization of scientific research in situ typical. I left Iron are in Shandong Province, deputy director of Institute of Welding, introduce him copper and aluminum from the different characteristics of knowledge: copper density, scalability, and to connect the two ends of air-conditioning inside and outside the machine can only use copper to ensure tightness and compression of , while the middle part of the pipe to ensure that only play the role of flow, so as long as the solution to copper and aluminum connection problem, the use of aluminum in place of copper there is no problem. Left Iron Army, said several patents Haiqing 30 resistance pressure welding method, to achieve a weld-free aluminum brittle organization, copper and aluminum atoms combine, weld very strong, whether it is stretching, bending, flattening is not there will be any gap. “Until now, Haiqing the first to market products that have been the first five years. But so far there is no question the quality of complaints. In accordance with the enterprises of general standards, brass failure rate requirement is lower than the 1.6 great , and Haiqing of him as a failure rate of 0.1. “

, however, left feeling Iron and Zhao Yue Unfortunately, compared with last year, domestic air-conditioning businesses to use copper and aluminum tubes did not increase the total amount, which means that the domestic air-conditioning this year on behalf of enterprises in the aluminum copper applications still in a stagnant state. “The reason is that happened between the last air-conditioning business of the struggle between the copper and aluminum that war of words.” Zuo said Iron.

the sequelae of a marketing plan on behalf of

copper aluminum upper reaches of the technology such as a household name but also “thanked” the United States last year, planning a marketing campaign.

introduction, according to informed sources, the United States in the first half of last year has been meticulously planned, in large air-conditioned store held a “Wing-knot copper” activities, but also specialized printed on “brass” and “copper-aluminum connecting pipe “advantages and disadvantages of comparative table, copper-aluminum connecting pipe directed at a” density, soft texture; Life expectancy short, the effect of poor refrigeration; compression weak, easily lead to the bursting of “the three major disadvantage.促销员beauty even terminal directly to the aluminum tube known as the “black heart tube.”

directly provoked the United States and the planning in July last year in air-conditioning industry, copper and aluminum pipe about a war of words, although at that time, including the Association of Chinese household electrical appliances, including a number of authoritative bodies to stand up on behalf of support of Al-Cu technology, but the controversy has not been fully resolved consumer cognitive errors, so many consumers substituting aluminum for copper this new technology have the attitude of exclusion. In addition, the country of copper and aluminum pipe to connect the standard has not yet been introduced, resulting in more than air-conditioning business slowed down the pace of Al-Cu substitution.

It is understood that Hisense Kelon in July last year for copper and aluminum tube held a news conference, a high-profile announcement on behalf of Kelon air-conditioned aluminum copper connecting pipe from the original warranty period of 3 years to 10 years. But this year, Hisense Kelon of copper and aluminum tubes are deliberately keeping a low profile. Although Haier Haiqing issued this year to more than one million sets of copper and aluminum tube orders, but that is just working hard at work, did not openly support Al-generation copper technology. And CHIGO Gree and more are to reduce the quantity of orders.

“Gree now in the United States claimed that its domestic sales of products useless copper and aluminum tubes, each contain two. Recently, the media broke the United States has also quietly increased the amount of copper and aluminum pipe , but on the surface are reluctant to openly admit, a marketing plan so that air-conditioning business-to-secrecy of this new technology, big business-to-industry effect can be seen. “Zuo Iron Say not without emotion.

waiting Gree

beauty left in accordance with the figures provided by Iron Army, Haiqing license last year, sales of copper and aluminum air-conditioning pipe connecting more than four million units this year, completed more than six million sets. This includes the United States, South Korea, Japan, Brazil, India more than one million sets of business orders. “This means that the domestic air-conditioning businesses to use the total amount of copper and aluminum tubes did not increase in the basic.”

“So far, Gree and the United States are the only export products that use copper and aluminum tubes.” but left Iron believe: “The domestic air-conditioning companies will sooner or later recognized this technology.”

Iron Army left the accounts are counted this: Suppose the United States Gree home split air-conditioning for the production of the 10 million sets, a set of air-conditioning with copper and aluminum tubes to save fifty dollars on average, then the cost savings a year is 500 million million. “To know that air has entered the low-profit era, one-year net profit is五六亿million, a tube I can for him so many provinces, he is no reason why not”! Iron

left another reason is that this year, the United States, South Korea, Japan, Brazil, India and other countries began to frequent air-conditioning giant sent to Haiqing inspection and gradually increase the copper and aluminum pipe orders, only a large air-conditioning business in Korea next year, an order will be more than one million sets. Its domestic subsidiaries are also on the relevant products for testing next year there will be hundreds of thousands of sets of procurement volume, “If China does not speed up the air conditioning business to reduce costs and materials, alternative technology, is likely in the near future with foreign competition Medium at a disadvantage. “Iron left that are not without worries.

“Although the industry on behalf of a variety of aluminum mixed with copper technology, the industry there is a purge of the problem, although copper and aluminum pipe only to fully air-conditioned with copper 1 / 6, air-conditioning industry, substantially reducing costs also depend on the radiators, switches copper alternative, but substituting copper aluminum copper resources certainly represents a depletion of times the direction of development of air-conditioning industry, our task is to first make up this market. “Zuo said Iron.

air-conditioning industry veteran observers think

Yan-Bin Zhang national standards promulgated

can get rid of the obstacles to resource a wide range of aluminum substitution of copper scarcity of resources, are air-conditioning history of the development of a technical revolution. “Substituting copper in aluminum,” a simple look only reduces costs, but depth is a benefit to understand the contemporary, functional in the long-term technological progress, in favor of air conditioning products has further represented to the rural market penetration 34.

air-conditioning industry is the large consumption of copper in air-conditioning industry to promote the “Al-generation copper” of great significance, but the reality is that air-conditioning industry to carry out the “Al-generation copper” is still in its infancy, far from the other consumption copper large — the automotive industry in the faster alternative. In fact, air-conditioning business for the “Al-generation copper” in the industry can be promoted across the board are very much looking forward to, after all, this is a technological advancement, could alleviate the ever-increasing cost pressures. However, in the real environment of market factors are forcing the air-conditioning manufacturers only with caution. We are all waiting for the opportunity, if a country has promulgated standards introduced in the market promotion would be no worries. Introduction of national standards on the market is one of the ways to break barriers. (08-9-1)
