What unchangeable conditions should be determined first for non-standard customization of air-conditioning boxes?

Non-standard customization of air-conditioning boxes should first lock in the truly unchangeable conditions, such as transportation channels, installation boundaries, interface locations, available energy and required performance, and then distinguish negotiable items. Drawing a shell first and cramming in all the features makes it easy to rework it repeatedly during airflow, maintenance or manufacturing phases.

Give each restriction a basis and priority

On-site door openings, load-bearing and fixed air duct interfaces usually require actual measurements or drawings, and performance requirements require design confirmation. The tentative height or habitual takeover direction can be marked as an item to be optimized to leave room for the plan. Don't write all preferences as hard constraints, and don't treat real safety and performance conditions as arbitrary compromises on appearance dimensions.

Fixed conditions include space, transportation, load-bearing and confirmation data of existing interfaces; required performance includes air tasks, pressure, filtration and allowable operating range; negotiable items include shape allocation, segmentation methods and some interface adjustments. Only after the three types of conditions are distinguished can the discussion of the plan have boundaries. What information should be prepared before selecting an air-conditioning box? Please refer toWhat project information should be prepared before selecting an air-conditioning box?。

Transportation aisles and installation boundaries are usually the first to be locked

Just because the equipment can be built does not mean it can be transported to the site. Door opening width, elevator size, stair corners, hoisting space and floor load-bearing often limit solutions earlier than internal configuration. For units transported in sections, the maximum single section size and on-site connection method must be confirmed. Please refer toHow to choose between combined and integrated air conditioning boxes? andHow to identify the assembly sequence for segmented transportation of combined air-conditioning boxes?。

The installation boundaries include the length, width and height of the machine room, foundation location, wall distance and maintenance space. How to leave the maintenance side when arranging against the wall? Please refer toWhen a horizontal air-conditioning box is arranged against a wall, which side should be left for inspection? . Horizontal and vertical types require different space, please refer toWhat kind of space do horizontal air conditioning boxes and vertical air conditioning boxes require? . Whether the length of the device can be compressed when space is limited, please refer toCan the length of the horizontal air conditioning box be reduced when there is insufficient plane space?。

Interface location and available energy are hard conditions

The locations of existing air ducts, water pipes, electrical bridges and control interfaces are usually determined on site, and modifications are costly. The direction, diameter, and elevation of the interface should be confirmed at the early stage of the plan and cannot be adjusted after the equipment shape is determined. How to confirm the water system parameters, please refer toWhat water parameters should be confirmed before connecting the air conditioning box to the cold water system? . Whether the diameter of the water pipe can be determined directly according to the coil interface, please refer toCan the diameter of the water pipe in the air conditioning box be determined directly based on the coil interface?。

Available energy sources include power supply capacity, cold or hot water conditions, steam or humidified water sources. Electric heating capacity is limited by power distribution, and hot water coils are limited by water temperature and flow. These conditions determine which functional segments are feasible. How to choose between hot water heating and electric heating, please refer toHow to choose between hot water heating and electric heating for air conditioning boxes?。

Must-achieved performance is not negotiable

Air volume, external static pressure, air inlet and outlet status, filtration level and noise requirements are performance constraints. Reducing these requirements in order to adapt to the form factor is tantamount to changing the mission of the equipment. How to write the pressure caliber clearly, please refer toWhat is the difference between static pressure, total pressure and static pressure outside the air conditioner box? . How to determine the filtering classification, please refer toHow to configure the primary-efficiency and medium-efficiency filters of air-conditioning boxes in different stages?。

Performance constraints may also interfere with each other. Reducing the shape may compress the mixing distance or inspection space, increasing the number of filtration stages will increase resistance, and reducing noise may require a larger cross-section. How to arrange the sequence of function segments, please refer toOn what basis should the sequence of functional sections of the air conditioning box be determined? . For the influence of mixing distance, please refer toHow long is the air mixing distance required in the mixing section of the air conditioning box?。

How to manage subsequent changes

The plan confirmation record should list the frozen content, versions and items to be closed, and explain the impact on performance, delivery time and costs when making changes. If the on-site dimensions change, the structure, fans and electrical control equipment should be notified simultaneously to avoid updating only the outline drawings. Unconfirmed conditions should be retained as assumptions rather than passively entered into manufacturing.

When changes to the control interface are involved, the point table should be updated simultaneously. Please refer toWhat point tables need to be provided before the air-conditioning box is connected to the building automation system? . When it comes to foundation or drainage adjustments, you can refer toHow to determine the foundation height of a horizontal air conditioning box based on drainage conditions? . The change record should be able to correspond to the equipment number and drawing version.

Non-standard does not mean that all sizes can be redrawn

The space for non-standard customization lies in adjusting the structure, segmentation and interfaces according to site conditions rather than abandoning the basic design logic. There are still inherent requirements for the fan working point, coil heat exchange area, filtration wind speed and maintenance access. If you understand non-standard as 'everything can be changed', it is easy to find that some functions cannot be realized later.

Why should you check the efficiency range when selecting a fan? Please refer toWhy should we check the efficiency range when selecting air-conditioning box fans? . How to select the type of surface cooler according to the air inlet and outlet conditions, please refer toHow to select the type of air conditioner cooler according to the air inlet and outlet conditions? . These performance logic do not change due to non-standard.

Related questions and answers

Can all sizes be changed for non-standard customization?
no. The structure, sections and interfaces can be adjusted on site, but the fan working point, coil heat exchange area and maintenance access still have inherent requirements and cannot be compressed at will.

The on-site dimensions have not been measured yet. Can you come up with a plan first?
A preliminary assessment can be made first, but the transportation channels, installation boundaries and interface locations should be marked as pending verification, and the plan will be frozen after actual testing.

Can Aili Industrial help sort out non-standard constraints?
Feasible solutions can be evaluated based on site constraints, performance requirements, and interface conditions. Specific configurations need to be confirmed based on actual measurement data and project conditions.
