静压箱有没有无所谓，一般来说都是一个空箱子，用来方便机房接管，按照规定是断面流速小于2，实际上除了接管并没有其他作用，如果需要按消声器的话。送风根据送风量和安装位置来确定风速和送风口的尺寸大小。回风根据回风量来确定回风口面积，回风一般风速小与2， 长宽则以安装位置来确定。根据以上大概做好选型，再把长管算下风阻，只要小与机组机外静压就可以了。
It doesn't matter whether there is a static pressure box or not. Generally speaking, it is an empty box to facilitate the connection of the machine room. According to the regulations, the cross-section flow rate is less than 2. In fact, it has no other function except the connection. If it is necessary to press the muffler. The air supply determines the wind speed and the size of the air supply outlet according to the air supply volume and installation position. The area of the return air outlet is determined according to the return air volume. The return air generally has a small wind speed of 2, and the length and width are determined according to the installation position. According to the above, select the type, and then calculate the wind resistance of the long pipe, as long as the static pressure outside the unit is small.
暖通工程是整个建筑工程的收尾工作，所以尾期工程一定要做到细致。无论是施工单位采购材料还是甲方供应材料，技术人员都要对其规格、型号、质量进行全面严格检查，对质量检查合格单、合格证件检查不合格的不予进场，要求必须各项测验报告符合国家技术标准和设计要求。防腐、保温工程的质量控制。要求保温材料粘贴牢固、接口严密，隔气防潮层要严密。水管、风管在穿墙、穿楼层处和技术缝处保温层连续紧密，管道和作垫用的木条防腐要合格。
HVAC project is the final work of the whole construction project, so the final project must be meticulous. Whether the materials are purchased by the construction unit or supplied by Party A, professional technicians shall comprehensively and strictly check their specifications, models and quality. Those who fail to pass the quality inspection form and certificate shall not enter the site. It is required that all test reports must meet the national technical standards and design requirements. Quality control of anti-corrosion and thermal insulation works. The thermal insulation material shall be pasted firmly, the interface shall be tight, and the gas barrier and moisture-proof layer shall be tight. The insulation layer of water pipe and air pipe shall be continuous and tight at the places where they pass through the wall, floors and technical joints, and the anti-corrosion of pipes and wooden strips used as pads shall be qualified.
由于建筑空间的控制，以及管道加工难度大的问题，要将管道之间紧密的排列在一起，从而实现整个管道施工布局的合理性和功能的完整性。这也是管道施工的基本原则。?看完上述的内容您就知道空调管道施工要注意的原则是什么了，这样的施工方式不仅有利于管道的排列合理化，而且还能节约管道的使用量，在用户的角度上来讲是非常有用处的。
Due to the control of building space and the difficulty of pipeline processing, the pipelines should be closely arranged together, so as to realize the rationality and functional integrity of the whole pipeline construction layout. This is also the basic principle of pipeline construction.? After reading the above contents, you will know what principles should be paid attention to in the construction of air conditioning pipes. Such construction method is not only conducive to the rationalization of pipe arrangement, but also saves the use of pipes. It is very useful from the perspective of users.
