Can the evaluation of non-standard solutions be started if the air-conditioning box only has installation drawings?

When the air-conditioning box only has installation drawings, you can first evaluate the feasibility of space, transportation, interfaces and maintenance, but it is usually not enough to complete the performance selection. The installation diagram explains where the equipment is placed and how to connect it. It is still necessary to add air tasks, air volume and pressure, air inlet and outlet status and available energy to determine the internal configuration.

Separate what can be read on the diagram from what is still missing

The installation diagram may have outlines, air inlets and water pipe locations, but it does not indicate at what pressure the air volume is achieved, nor does it give the moisture content of the outlet air that the coil needs to achieve. It should be noted whether the dimensions have been measured, whether the interface can be changed, and the missing performance inputs should be listed item by item. If the drawing version is inconsistent with the on-site version, on-site verification is required first.

You can first evaluate the outline boundaries, transportation, interfaces and maintenance paths; you must complete the air volume pressure, air status, cold and heat sources and filtration tasks; you need to confirm the actual measurement basis, drawing version and which interfaces can be adjusted. The three types of information correspond to different evaluation depths, and the preliminary sketch cannot be regarded as the final equipment confirmation drawing.

What preliminary judgments can the installation diagram support?

Installation drawings can support preliminary judgments about space feasibility, transportation access, interface orientation, and access space. Whether the shape of the equipment can fit into the computer room, whether the segment size can pass through the door opening, and whether the air duct and water pipe interfaces match the site, these issues can be initially evaluated during the installation drawing stage.

Horizontal and vertical types require different space, please refer toWhat kind of space do horizontal air-conditioning boxes and vertical air-conditioning boxes require? . Transportation channel and section identification, please refer toHow to identify the assembly sequence for segmented transportation of combined air-conditioning boxes? . These preliminary judgments can help narrow the scope of solutions, but they cannot replace performance selection.

Internal configuration cannot be locked when performance parameters are missing

Without the air volume, external static pressure and air inlet and outlet status, it is impossible to determine the number of coil rows, filter area, fan operating point and functional section length. Without hot and cold source conditions, it is impossible to determine the hot water coil, electric heating or humidification method. Without target gas or particle requirements, filtration levels and chemical filter section configurations cannot be determined.

Non-standard constraints should be marked with priority

On-site door openings, load-bearing and fixed interfaces usually require actual measurements or drawings, which are relatively hard constraints; there may be some room for negotiation in shape allocation, segmentation methods and some interface adjustments. In the installation drawing stage, constraints can be divided into fixed conditions, necessary performance and negotiable items, and it can be marked which dimensions have been measured and which are still tentative.

The priority of constraints is clear, and you will know which ones can be adjusted and which ones cannot be moved until you add parameters later.

How to advance the initial evaluation to a manufacturable solution

First, space feasibility opinions and a list of missing data are formed, and then the designer or project party completes the performance conditions. The tentative items in the plan should be clearly marked and closed one by one before the technology freeze. The preliminary outline sketch cannot be regarded as the final equipment confirmation drawing, and it is not advisable to directly lock the fan or coil when key working conditions are missing.

After completing the data, check the order of the function segments. Please refer toOn what basis should the sequence of functional sections of the air conditioning box be determined?。

Aili industrial supporting equipment

After submitting the installation drawing to Aili Industrial, you can gradually fill in the parameters according to the missing items list, so that non-standard structure evaluation and performance selection can be promoted under the same version. 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. The installation boundaries, transportation sections, interface positions and internal configurations can be matched in the same package; non-standard boxes can be confirmed in stages according to the on-site space and data completion.

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 solutions. The feasibility, performance and delivery scope of the specific solution still need to be verified based on the completed technical data and on-site working conditions. Actual results are subject to on-site leak detection and performance test results.

Related questions and answers

I only have installation drawings, can I quote directly?
A preliminary price range can be given, but the performance configuration has not been determined, and the quotation can usually only be used as a reference and cannot be used as the final contract price.

Can the dimensions on the installation diagram be used directly for manufacturing?
Not recommended. It should be confirmed whether the dimensions are actually measured and whether the drawing version is consistent with the site before freezing the structural plan.

Can Aili Industrial make a preliminary assessment based on the installation drawings?
You can first make a preliminary assessment of the space and interfaces, and list the parameters that need to be completed. The specific configuration needs to be confirmed after the information is complete.
