风管验收的步骤通常包括以下几个关键环节，以确保风管系统的安装质量和性能符合设计要求及相关标准：

　　The steps of duct acceptance usually include the following key steps to ensure that the installation quality and performance of the duct system meet the design requirements and relevant standards:

　　一、检查设备与材料

　　1、 Check equipment and materials

　　核对内外机型号：确保风管机的内外机型号与合同或设计图纸上的一致。

　　Check the models of the internal and external units: Ensure that the models of the internal and external units of the air duct fan are consistent with those on the contract or design drawings.

　　检查机器外观：查看风管机及辅助设备（如铜管、保温管、冷凝管等）是否有磕碰变形或损坏。

　　Check the appearance of the machine: Check whether the air duct fan and auxiliary equipment (such as copper pipes, insulation pipes, condenser pipes, etc.) are bumped, deformed or damaged.

　　核对辅料品牌型号：检查所有使用的辅料（如螺丝、管卡、扎带等）的品牌和型号是否符合要求。

　　Verify the brand and model of auxiliary materials: Check whether the brand and model of all auxiliary materials used (such as screws, pipe clamps, zip ties, etc.) meet the requirements.

　　二、检查安装工艺

　　2、 Check the installation process

　　内机安装：

　　Installation of internal unit:

　　检查吊杆是否使用双螺母减震，以减少运行噪音。

　　Check if the suspension rod uses double nuts for shock absorption to reduce operating noise.

　　确保内机至少下吊2厘米，避免出风口受遮挡。

　　Ensure that the internal unit is lowered at least 2 centimeters to avoid blocking the air outlet.

　　检查内机安装后是否用保鲜膜缠绕并包裹防尘罩，以及是否标注了出风口和回风口的尺寸。

　　Check whether the internal unit is wrapped with cling film and wrapped with a dust cover after installation, and whether the dimensions of the air outlet and return outlet are marked.

　　管卡与密封：

　　Pipe clamps and seals:

　　检查管卡间距是否符合要求（通常为1.2米）。

　　Check if the spacing between pipe clamps meets the requirements (usually 1.2 meters).

　　确保螺丝管卡使用不锈钢材质，以提高耐腐蚀性。

　　Ensure that the screw pipe clamp is made of stainless steel material to improve corrosion resistance.

　　检查接头处是否用扎带密封，墙缝接触处是否打发泡胶防止移位。

　　Check if the joints are sealed with zip ties, and if foam glue is applied to the wall joints to prevent displacement.

　　铜管与排水管：

　　Copper pipes and drainage pipes:

　　检查铜管折弯是否使用折弯机，避免折扁影响流量。

　　Check if a bending machine is used for bending copper pipes to avoid flattening and affecting flow.

　　确保排水管有坡度，方便冷凝水排出。

　　Ensure that the drainage pipe has a slope to facilitate the discharge of condensed water.

　　检查排气管是否做弯头，防止灰尘进入。

　　Check if the exhaust pipe is bent to prevent dust from entering.

　　电源线：检查空调电源线是否达到4平方以上，以防止过载发热产生安全隐患。

　　Power cord: Check if the air conditioning power cord is over 4 square meters to prevent safety hazards caused by overload and heating.

　　三、性能测试与实验

　　3、 Performance testing and experimentation

　　冷媒管路打压测试：对冷媒管路进行打压测试（如40公斤压力），保压48小时检查气密性。

　　Refrigerant pipeline pressure test: Conduct a pressure test on the refrigerant pipeline (such as 40 kg pressure), hold the pressure for 48 hours, and check the airtightness.

　　冷凝水管排水实验：进行冷凝水管排水实验，确保排水顺畅无阻。

　　Condensation pipe drainage experiment: Conduct a condensation pipe drainage experiment to ensure smooth and unobstructed drainage.

　　运行测试：开启风管机进行运行测试，检查是否有异常噪音、振动或漏风现象。

　　Run test: Turn on the air duct fan for a run test to check for any abnormal noise, vibration, or air leakage.

　　四、记录与报告

　　4、 Record and Report

　　记录验收结果：详细记录每一步的验收结果，包括合格与不合格项。

　　Record the acceptance results: Detailed records of each step's acceptance results, including qualified and unqualified items.

　　编写验收报告：根据验收结果编写验收报告，总结风管机的安装质量和性能是否符合要求。

　　Write acceptance report: Based on the acceptance results, write an acceptance report summarizing whether the installation quality and performance of the air duct fan meet the requirements.

　　整改与复验：对于不合格项，要求安装单位进行整改，并重新进行验收直至合格。

　　Rectification and re inspection: For non-conforming items, the installation unit is required to rectify them and conduct re acceptance until they are qualified.

　　综上所述，风管验收的步骤涵盖了设备与材料的检查、安装工艺的检查、性能测试与实验以及记录与报告等多个方面。这些步骤确保了风管系统的安装质量和性能符合设计要求及相关标准，为后续的使用和维护提供了有力保障。

　　In summary, the steps of air duct acceptance include equipment and material inspection, installation process inspection, performance testing and experimentation, as well as recording and reporting. These steps ensure that the installation quality and performance of the duct system meet the design requirements and relevant standards, providing strong support for subsequent use and maintenance.
