How to identify the assembly sequence for segmented transportation of combined air-conditioning boxes?

When transporting combined air-conditioning boxes in sections, the equipment number, section serial number, wind direction, observation direction and interface markings should correspond to each other. The assembly sequence should be traceable from the packaging list and drawings. You cannot just use 'first paragraph, second paragraph' without indicating the unit to which it belongs. In particular, it is necessary to prevent multiple similar equipment from being mixed.

Allow on-site personnel to find the drawing location from the label

Each transport unit should have a clear and transport-resistant identification mark, and the list should indicate the quantity, main accessories and corresponding connection surfaces. Segment numbers can be arranged along the direction of air flow, but directional arrows and confirmation diagrams are still required. The purpose of fasteners, sealing materials and individually packaged accessories should also be clearly stated to avoid guessing based on appearance after arrival.

The identity information should include the project, equipment number and independent segment number; the direction information should include the wind direction, adjacent segments and confirmed observation standards; the attachment information should include the corresponding relationship between connecting materials, independent components and packing list. The three types of information correspond to different verification links, and cannot just be posted with one paragraph number.

Segment numbers should be arranged along the direction of air flow

Section numbers are usually arranged along the direction of air flow to make it easier for on-site personnel to understand the assembly sequence. The number can be written as 'Equipment Number-Section Serial Number', for example, 'AHU-01-03' means the third section of Unit 1. Just write 'first paragraph, second paragraph' without indicating the unit it belongs to, which is easy to mix when multiple similar equipment arrives at the same time.

The numbering should also match the wind direction arrow. The wind direction arrow indicates from which side the air enters and from which side the air is sent out. The observation reference should be unified as the operating side or the non-operating side. How to determine the order of function segments, please refer toOn what basis should the sequence of functional sections of the air conditioning box be determined?。

Adjacent connecting surfaces and interfaces should be marked in pairs

The connecting surfaces on both sides of each segment should be marked accordingly, such as 'AHU-01-02 to AHU-01-03'. Flanges, air inlets, water pipes and electrical interfaces should be marked with their respective segments and connection objects. The sealing gaskets, fasteners and connection accessories of the connection surface should be packaged with the corresponding sections or independently, and marked in the list.

The sealing quality of the segmented joints will affect the air leakage of the box. Please refer toUnder what pressure conditions should the air leakage rate of air conditioning boxes be compared? . The protection of the connection surface should be done well during the transportation stage, please refer toHow should the air vents and pipe joints of air-conditioning boxes be protected before leaving the factory for transportation?。

Label materials must adapt to transportation and on-site environments

Labels should be resistant to transportation vibration, moisture-proof, non-shedding, and remain readable during on-site installation. Double markings can be set inside and outside the packaging. The outer packaging label facilitates unloading and inventory, and the internal segmentation label facilitates installation and verification. If the label is damaged during transportation, it should be traceable through the packaging list and drawing number, and cannot be judged based on the appearance alone.

The equipment number and section number should be consistent with the packing list, delivery list and drawings. When multiple similar units arrive at the same time, it is recommended to add a unit number color code or area mark outside the package to reduce the risk of mixed packaging.

Accessories and independent packaging must be listed separately

Fasteners, sealing materials, flange gaskets, sensors, actuators and special tools should be packaged separately and marked with the corresponding unit and segment. The accessory package number should be associated with the segment number to avoid finding the corresponding accessory during installation. The list should indicate the quantity, specifications and usage, and cannot just say 'one box of accessories'.

For the removal and inventory of transportation protection parts, please refer toHow should the air vents and pipe joints of air-conditioning boxes be protected before leaving the factory for transportation? . The hanging point and center of gravity identification should also correspond to the section number, please refer toCan the loading and unloading lifting points and operating lifting points of the air-conditioning box be mixed?。

How to use markings during unloading and assembly

When arriving at the site, first check the damage and missing parts according to the list, and then arrange them according to the on-site installation path to avoid discovering that the order of the sections is reversed after assembly. When the label is damaged or the drawing is inconsistent, the version should be verified first. After the connection is completed, keep the final serial number and assembly record of the device so that subsequent maintenance can have a corresponding basis.

For on-site placement, the maintenance side and foundation position should also be considered. Please refer toWhen a horizontal air-conditioning box is arranged against a wall, which side should be left for inspection? . Foundation height and drainage conditions, please refer toHow to determine the foundation height of a horizontal air conditioning box based on drainage conditions?。

Assembly records must be traceable

After assembly is completed, each section number, actual installation sequence, connection surface sealing inspection results and accessory usage should be recorded. If the segment sequence is adjusted or accessories are replaced on-site, the reason and version should be stated in the record. Before debugging, you can check the sequence of functional segments and interfaces against the records to reduce the difficulty of subsequent troubleshooting.

Aili industrial supporting equipment

When confirming segmented delivery with Aili Industrial, the label and list format can be agreed in advance so that manufacturing, transportation and on-site installation use the same set of numbers. Aili's industrial manufacturing end covers the independent research and development and production of motors and fans, control systems, sheet metal, air filters and complete machine assembly. Equipment numbers, segment structures, connection surfaces and accessory lists can be corresponded in the same set of delivery materials; non-standard segments can be marked according to the transportation size and on-site installation sequence.

Product form can be viewedAir handling unit andFan box page; clean air supply package can be combinedFFU fan filter unit andEFU equipment end fan filter unit verification; terminal particle filtration can be combinedHEPA/ULPA filter confirmation; when it comes to gaseous pollution control, you can communicate separatelyChemical filter solution; multiple devices can be linked together to understandFFU computer group control system . Supporting method of The specific marking scheme, assembly records and delivery scope still need to be confirmed based on the corresponding configuration data and on-site transportation conditions. Actual results are subject to on-site assembly inspection and performance test results.

Related questions and answers

Is it enough to just write 'the first paragraph and the second paragraph'?
not enough. The equipment number, wind direction and adjacent sections should be marked at the same time, otherwise it will be easy to mix and install multiple similar equipment when they arrive at the same time.

What should I do if the label is damaged during transportation?
It should be traceable through the packaging list, delivery list and drawing number, and the segment sequence cannot be judged based on the appearance alone.

Can Aili Industrial help develop a segmented signage plan?
The numbering, labeling and list format can be agreed upon based on the segmented structure, transportation method and on-site installation sequence. The specific plan needs to be confirmed according to the project conditions.
