通风空调风管制作与安装要点(国外英文资料) Ventilation and air conditioning duct production and installation points With the improvement of high-grade writing room and office environment, air-conditioning system is more and more widely used in daily life. How to make the selected air conditioning system to achieve the best results, in addition to the rationality of the design, air conditioning ventilation project construction is also an important factor. As an important part of air conditioning ventilation project, the construction quality of air duct directly affects the installation quality and operation effect of the system. In a number of air conditioning and ventilation engineering, because of the wind pipe fabrication and installation quality problems caused by the lack of the air leakage, exceed the standard requirements, resulting in energy waste, insufficient heat and air conditioning ventilation engineering operation unstable phenomenon, affect the normal operation of air conditioning. In this paper, the manufacture and installation technique of air duct, common quality problems and corresponding countermeasures are introduced in combination with a specific engineering example of air conditioning ventilation project. 1. air pipe assembly technology A building is a meeting, guest, negotiation, conference center, exhibition in a comprehensive building, two floors underground, five floors on the ground, the ground floor of the two floor for the power distribution room, equipment and property management room. Two kinds of air conditioning chilled water of the building air conditioner adopt a 3.3 DEG ~14.4 DEG, provided by a set of ice storage device used for building air conditioning box all units; another is 7.8 DEG ~14.4 DEG, provided by a conventional chiller, air supply and future use of coil. The ice storage system is set according to the partial load of ice storage, ice storage and ice storage tank in series to the host, the host upstream, design condition operation strateg
