螺旋风管-随着暖通空调行业不断发展，产品布局正在悄然发生变化。低碳节能已经成为暖通空调产品的基本诉求。暖通空调企业不断运用先进的科技，提高空调产品的能效等级，开发能源替代和再生能源利用，研制新制冷剂等。

Spiral duct - with the HVAC industry development, product layout is quietly changing. Low carbon energy saving has become the basic demands of HVAC products. HVAC enterprises continue to use advanced technology, improve the energy efficiency of air-conditioning products, develop energy alternative and renewable energy utilization, develop new refrigerants, etc..

螺旋风管市场上按材质一般分为三类：镀锌螺旋风管、不锈钢螺旋风管以及复合螺旋风管。为了使设备达到节能环保的目标，各企业均围绕节能环保的主题开展相关活动， 在新产品开发、产品设计、制造工艺、生产线技术改造等方面加大投入力度，促进设备的升级。同时，在生产方面也注重节能，各企业均制订完善的考评系，在产能增加的前提下努力争取降低能耗，生产中间环节也尽量减少污染物的排放。

The spiral pipe market is generally divided into three types according to the material: galvanized spiral duct, stainless steel spiral duct and composite spiral duct. In order to enable the equipment to achieve the goal of energy saving, energy saving and environmental protection enterprises all around the theme of the activities, to increase investment in new product development, product design, manufacturing technology, production line technological transformation, promote the upgrading of equipment. At the same time, the production also pay attention to energy saving, each enterprise is to develop a sound evaluation system, in the premise of increasing production capacity, strive to reduce energy consumption, production in the middle link also try to reduce the emission of pollutants.

螺旋风管的安装显著地减少了管与管之间的连接点，使管件结合部的泄漏减少到最低程度，典型的螺旋风管长度是3~6m，而典型的矩形风管的长度只有1~1.5m；且连接两 个螺旋风管只需一个管接件，而传统的螺旋风管的连接则常常需要一个完全独立的双法。

Installation of spiral duct significantly reduces the connection point between the pipe and the pipe, the pipe leakage with reduced to the lowest level, the typical spiral duct length is 3~6m, and the typical rectangular duct length is 1~1.5m; and connecting the two spiral duct just a pipe connector, and the traditional spiral tube connection is often in need of a fully independent dual method.
