通风新风系统使用仍有待发展

新风系统在欧洲国家的家庭使用率在90%以上,而在我国的使用率仅为0.5%左右。新风系统从商用领域向民用领域推广之所以遇到阻力,与消费者对新风系统的认知误区有关。很多人都将新风换气机与换气扇、排风扇相混淆。
Fresh air systems are used by more than 90% of the households in European countries, while in China the use rate is only about 0.5%. The resistance to the promotion of fresh air system from commercial field to civil field is related to the misunderstanding of consumers. Many people confuse the fresh air ventilator with the ventilator and exhaust fan.
通风是住宅健康的关键,房屋密闭容易滋生霉菌,影响人体健康。但是,经常开窗通风,冬天不能保暖,夏天又浪费冷气,新风系统很好地解决了建筑通风与节能两个问题。在建筑上使用时,新风换气机是空气-空气能量回收通风装置的俗称,也称新风能量回收装置,新风换气机在换气的同时,还能对排风进行能量回收,是一种能对室外空气进行净化处理、对室内排风进行能量回收的建筑环境节能、净化用换气设备。
Ventilation is the key to the health of a house. It is easy to breed mold and affect human health. However, often open the window ventilation, winter can not keep warm, summer and waste of air conditioning, fresh air system to solve the building ventilation and energy-saving two problems. When used in buildings, fresh air ventilator is commonly known as air-air energy recovery ventilation device, also known as fresh air energy recovery device, fresh air ventilator can recover energy from exhaust air while ventilating. It is an energy-saving building environment that can purify outdoor air and recover energy from indoor exhaust air. And ventilation equipment for purification.

据统计,都市人有70%~80%的时间是在室内度过的,老弱病残和儿童在室内的时间更长,可达90%以上。另据美国专家的研究显示,室内空气污染的程度要比室外严重2~5倍,人类大部分疾病是由室内空气污染造成的。2003年的;非典、2009年;甲流;的爆发,让人们开始认识到空气质量对于人体健康的重要作用。
According to statistics, 70% to 80% of urban people spend time indoors, and the elderly, infirm, disabled and children spend more time indoors, up to 90%. According to American experts, indoor air pollution is 2-5 times more serious than outdoor air pollution. Most human diseases are caused by indoor air pollution. The outbreak of SARS in 2003 and influenza A in 2009 has made people realize the important role of air quality in human health.
目前我国新风行业的生产企业以中小企业为主,年产值大约只有三四千万元,即便是最近几年,新风行业取得了一定发展之后,年产值能够过亿元的新风产品生产企业仍然很少。
At present, the production enterprises of fresh air industry in China are mainly small and medium-sized enterprises, and the annual output value is only about 34 million yuan. Even in recent years, after the new wind industry has made certain development, there are still few fresh air product manufacturers whose annual output value can exceed 100 million yuan.
新风系统生产企业的规模普遍较小与其行业性质有关,通风空调末端本身大企业就很少,所以单独做热回收的企业更不会太大。由于新风系统生产企业的规模普遍较小,没有规模优势,难以降低成本,使得新风系统向中低端住宅市场推广步履维艰。不仅是生产规模,在生产工艺上,新风行业也存在着瓶颈。新风系统的很多生产企业,都采用OEM(代加工)的形式加工新风系统,这些企业并不具备自己的生产车间。另外,对于新风全热交换器的生产工艺,国内在关键技术(热交换芯体)上还没有取得突破,主要依赖进口。
The scale of fresh air system manufacturing enterprises is generally small related to the nature of its industry, ventilation and air-conditioning terminal itself on the small number of large enterprises, so a separate heat recovery enterprise will not be too large. Because the scale of the production enterprises of fresh air system is generally small, there is no scale advantage, it is difficult to reduce costs, making it difficult to promote the fresh air system to the low-end residential market. Not only is the scale of production, but also the bottleneck of the new wind industry in the production process. Many manufacturers of fresh air system use OEM to process fresh air system. These enterprises do not have their own workshop. In addition, for the production process of fresh air total heat exchanger, there is no breakthrough in the key technology (heat exchange core) in China, mainly relying on imports.
