The global construction market is pursuing different ways of improving energy efficiency, and actively investing in energy efficiency solutions to meet the increasing cost of energy, while not lowering the quality of service. The commercial sector is adopting more green systems in the building to enhance the comfort and efficiency of the indoor environment, improve energy efficiency and reduce the impact on the external environment. As a result, these systems can receive energy and environmental design (LEED) certification or energy star certification.
Analysis and forecast, in the 2017-2021 years period, the global HVAC pipe market will increase by 5.25% CAGR (CAGR). Heating, ventilation, and air conditioning are among the most energy intensive systems in commercial and residential buildings. Ventilation ducts are used for air distribution in HVAC systems. The ventilation, return air and exhaust air necessary for a HVAC system are required through the air duct. Ducts are also used for ventilation. As a result, the air duct is also a method of ensuring indoor air quality and thermal comfort.
The development of the construction industry has greatly promoted the global HVAC duct market. New buildings in residential, commercial and industrial areas have increased the demand for HVAC systems, thus creating demand for wind pipes. Architectural design innovations and concerns about building energy efficiency have created a good opportunity for HVAC manufacturers to expand their market size.
At the same time, the HVAC market is a capital intensive industry, which limits the wider use of HVAC systems, which has had a negative impact on the air duct market. Suppliers of HVAC market are faced with the difficulties of equipment development and market development. Many end users are also very much involved in the purchase of HVAC equipment because it requires a lot of initial investment. Especially in developing countries, high costs have prevented many families from buying household fireplaces, air conditioners and other electrical equipment.
SIG dedicated to the manufacture of wind pipe production line for nearly 20 years, has rich experience in equipment manufacturing, the production of automatic air pipe production line performance stability, high efficiency, can meet the demand of the wind pipe manufacturers growing, to create more economic benefits for wind pipe manufacturers.
Precautions for maintenance of duct production line
The normal operation and operation of the duct production line can not be separated from the normal operation of the air duct machine. Therefore, in order to ensure the normal operation of the machine, and ensure that the daily air duct production does not stop failure, it is necessary to maintain and maintain the pipe production machine. Comifo, the duct production line manufacturer, said that the maintenance of the duct line should be carried out from all aspects
1, for the duct cleaning system, flexible pipe material requirements are relatively high, must have dustproof, airtight, smooth and so on. The connection between the pipe and the duct equipment must be more strict. And the appearance of the tuyere requirements are more stringent, the quality should be qualified, border and blade to be smooth and smooth.
2, in the production of air valve, there should be signs of opening and closing. Multi blade valve blade joints need to overlap consistent, and wheelbase deviation in less than 1mm. For flexible pipe, the tightness should be suitable, the length should be within the scope of construction specifications, and meet the design requirements. Cracking and twisting are not allowed.
3, the hood production requirements, the specific performance of the complete rules, keep balance of shape, size deviation within 2mm per meter. Fire valve rotating parts need corrosion resistance is very strong, and its close to tight airtight.
Structure and function of fire damper
What are the structures and functions of fire dampers?
On the air duct of the air conditioning system, the purpose of the installation of fire dampers is to quickly cut off the air flow in case of fire, so as to prevent the fire from spreading. The fire valve diagram, when the fire duct, influence by ambient temperature and temperature, so that when the fire duct reaches a certain temperature, the fusible film fuse, the valve plate connected by the original fusible film and then fusible film closed stop airflow through off. In order to stop supplying air to the system and to install electrical signals and interlocks on the fire damper, the valve plate will signal when it is closed so that the fan will stop running.
Fire valve installation position:
(1) the main air duct on the air outlet of the air conditioning equipment (fresh air unit, unit, etc.).
(2) air passage through fire compartment.
(3) the air passage passes through the expansion and subsidence joint of the building structure.
(4) air passage, in unavoidable circumstances, through flammable workshops or rooms. The fire valve can be divided into self tipping, fire control valve type, manual reset, fusible film movement temperature is 70 DEG C.
