The ventilation system installed will help control the temperature, add oxygen or remove odors, moisture, harmful bacteria as well as CO2. When the air source is circulated through this system, the outside air will be brought in, and at the same time, the exhaust gas from the inside will also be pushed out, forming a continuous circulation cycle, helping to prevent air pollution. prevent stagnation of the air.<\/p>\n<p><strong>Typical construction ventilation systems of P69.JSC:<\/strong><\/p>\n<ul>\n<li>Factory ventilation system.<\/li>\n<li>Office ventilation system.<\/li>\n<li>Ventilation system basement, garage.<\/li>\n<li>The ventilation system pressurizes the stairs.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-322 aligncenter\" src=\"https:\/\/khachhang2.web3b.com\/hdec\/wp-content\/uploads\/2021\/12\/mau-chinh-mau-anh-300x160.jpg\" alt=\"\" width=\"964\" height=\"514\" srcset=\"https:\/\/p69.com.vn\/wp-content\/uploads\/2021\/12\/mau-chinh-mau-anh-300x160.jpg 300w, https:\/\/p69.com.vn\/wp-content\/uploads\/2021\/12\/mau-chinh-mau-anh-600x320.jpg 600w, https:\/\/p69.com.vn\/wp-content\/uploads\/2021\/12\/mau-chinh-mau-anh-1024x545.jpg 1024w, https:\/\/p69.com.vn\/wp-content\/uploads\/2021\/12\/mau-chinh-mau-anh-768x409.jpg 768w, https:\/\/p69.com.vn\/wp-content\/uploads\/2021\/12\/mau-chinh-mau-anh-1536x818.jpg 1536w, https:\/\/p69.com.vn\/wp-content\/uploads\/2021\/12\/mau-chinh-mau-anh.jpg 1600w\" sizes=\"auto, (max-width: 964px) 100vw, 964px\" \/><\/p>\n<p><strong>When installing ventilation systems, we need to comply with the following regulations:<\/strong><\/p>\n<ul>\n<li>All dimensions must be checked on site prior to duct production.<\/li>\n<li>All ductwork installation must be carried out by a specialist approved for duct manufacture and installation. Ducts should not come into direct contact with the building structure or building finishes but must be isolated by means of an isolating pad.<\/li>\n<li>Manufacturing shall be carried out in a compact and finished manner with all ducts of the correct size\u00a0dimensions and cross-sections, braced and stiffened as specified and all internal and external surfaces not protruding and have sharp edges.<\/li>\n<\/ul>\n<p>During the installation of the ventilation system, at each main branch in the duct, and the inlet and outlet of each fan, arrange a sufficient number of test holes to balance the system. Also, arrange test holes for fan ejectors and at all equipment. Inspection holes shall be located within easy reach of the working platform or ladder. Each inspection hole shall be of the appropriate size for the equipment used and shall be closed with a ribbed rubber stopper to ensure airtightness. The connection between ductwork sections must comply with\u00a0installation details.<\/p>\n<ul>\n<li>Reinforcement holes must be arranged at the place where thermometers, manometers, sensors, gauges, damper bars, etc. are installed in the pipeline. Expansion rings shall be provided for reinforcement holes where they are located in the insulated ductwork.<\/li>\n<li>In places where copper pipes go through ducts or equipment casings, rubber washers must be arranged to avoid damage to copper pipes.<\/li>\n<li>Ducts must be suspended or firmly supported from the building structure. Expansion bolts are used. Splints activated by particles generated by explosives are not acceptable.<\/li>\n<li>Angle trapezoidal hangers with supports up to 2m apart must use \u201cC\u201d beams, clamps will not be accepted. Provide necessary angle steel as required to brace ducts or equipment and to support ducts from the building structure.<\/li>\n<li>A layer of 5mm burlap of compressed thickness shall be provided between any supporting members which are designed to clamp or hold the pipe (e.g., round pipe strip clamps) or the member on which the pipe rests. All brackets are not hot-dip galvanized.<\/li>\n<\/ul>\n<ul>\n<li>Pipe size increase must be increased gradually. When the maximum width or dimension of the conduit is over 450mm, the pipes shall be reinforced by bending at a break-through corner in either direction.<\/li>\n<li>Ducts must be self-supporting. Single thickness bulkheads between pipes are not accepted. The interior parts that are visible through the vents will be painted matte black.<\/li>\n<li>All tolerances must be made during the \u201cinstallation of pipes\u201d to frame the structure of the building, and where changes or offsets are required, sections must be maintained.<\/li>\n<li>However, all these changes must be approved and installed according to the instructions at the time.<\/li>\n<li>During installation, the open ends of pipes should be protected by sealing, corrugated iron screens are fastened to prevent debris and dirt from entering.<\/li>\n<\/ul>\n<p><span style=\"font-size: 12pt;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-787 aligncenter\" src=\"https:\/\/khachhang2.web3b.com\/hdec\/wp-content\/uploads\/2022\/01\/He-thong-Thong-gio-3-300x169.jpg\" alt=\"\" width=\"957\" height=\"539\" srcset=\"https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/01\/He-thong-Thong-gio-3-300x169.jpg 300w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/01\/He-thong-Thong-gio-3-scaled-600x338.jpg 600w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/01\/He-thong-Thong-gio-3-1024x576.jpg 1024w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/01\/He-thong-Thong-gio-3-768x432.jpg 768w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/01\/He-thong-Thong-gio-3-1536x864.jpg 1536w, https:\/\/p69.com.vn\/wp-content\/uploads\/2022\/01\/He-thong-Thong-gio-3-2048x1152.jpg 2048w\" sizes=\"auto, (max-width: 957px) 100vw, 957px\" \/><\/span><\/p>\n<ul>\n<li>When pipes are shown connecting to openings along the edges of floors, walls, etc. Provide 30 X 30 X 4 mm galvanized angle steel that is bolted to the structure and must be gas sealed with compounds. putty in the corners.
