How to determine the foundation height of a horizontal air conditioning box based on drainage conditions?

The foundation height of the horizontal air-conditioning box should be determined based on the elevation of the drain outlet, water seal or other drainage structure, outer pipe slope and on-site discharge point, while meeting the load-bearing, vibration reduction and maintenance conditions. The foundation is not simply to raise the equipment; if it is too low, the drainage structure cannot be installed, and if it is too high, it may also cause difficulties in connection and maintenance.

Check the elevation backwards from the final discharge point

First determine the drainage access location and the required pipeline direction, and then check the space between the equipment drain outlet, drainage structure and the ground. If the negative pressure section requires water sealing, its structure is related to the pressure, and the height cannot be found after the equipment is in place. The shock absorber and base will also change the final elevation and should be reflected in the same section view.

The drainage chain should cover the elevation of the dish opening, drainage structure, outer pipes and access points; the structural chain should cover the foundation, base, vibration reduction and equipment load-bearing conditions; the maintenance chain should cover clearing, disassembly, access doors and surrounding pipeline spaces. The three chains correspond to different majors, and you cannot just give a basic height number.

What problems will arise if the foundation is too low?

When the foundation is too low, there is insufficient space between the water pan drain outlet and the ground, and the water seal or drain pipe may not be installed. The negative pressure section requires sufficient water seal height. If the foundation height is not enough, the water seal cannot be formed or is easily destroyed by the pressure difference. Insufficient slope of the external drainage pipe may also lead to poor drainage or backflow.

What is the difference between drainage in the positive pressure section and negative pressure section? Please refer toWhat is the difference between the positive pressure section drainage and the negative pressure section drainage of the air conditioning box?。

Too high a foundation will also affect takeover and maintenance

When the foundation is too high, the drainage outlet elevation increases, and the external drainage pipe may require a longer or larger slope to access the discharge point. The interface elevations of water pipes, air ducts and cables will also change, which may affect on-site takeover. Access doors and component extraction may require steps or platforms, making maintenance more difficult.

Please refer to the space required for horizontal and vertical air conditioning boxes.What kind of space do horizontal air conditioning boxes and vertical air conditioning boxes require?。

Dampers and mounts will change the final elevation

The equipment is usually mounted on a foundation, plinth or shock absorber. The amount of shock absorber compression, base height, and foundation flatness all affect the final drain elevation. If the design is calculated based only on the height of the equipment body, the drain outlet elevation may not match the drawings after on-site installation.

How to connect manufacturing and civil engineering drawings

The equipment party provides interface and base information, and the on-site design checks the foundation and drainage profile accordingly. If the discharge point is fixed, the need for interface or layout adjustments should be evaluated prior to fabrication. On-site padding should be confirmed by structure and installation. Scattered pads cannot be used to replace reliable foundations or change the stress conditions of the equipment.

How to verify drainage conditions during debugging

After installation, a controlled drainage inspection should be carried out to observe whether the water tray, drain outlet, water seal and outer pipe are unobstructed. The drainage condition of the negative pressure section should be checked under operating pressure. If water accumulation or backflow is found, you should first check the foundation height, water seal and pipeline slope before deciding whether to adjust.

Aili industrial supporting equipment

Aili Industrial can clarify the base and drainage outlet information in the confirmation drawing, and the project party will simultaneously provide the on-site drainage elevation, making it easier to close the installation conditions in advance. 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 base structure, drainage interface and box height can be corresponded in the same set of supporting materials; the non-standard foundation height can be adjusted according to on-site drainage conditions.

The specific foundation height, drainage plan and delivery scope still need to be confirmed based on the corresponding configuration data and site conditions. Actual results are subject to on-site drainage inspection and performance test results.

Related questions and answers

Is it okay to determine the basic height only based on the appearance of the equipment?
not enough. It should also be combined with the drainage outlet elevation, water seal structure, outer pipe slope and on-site discharge point. If the foundation is too low or too high, it may affect drainage and connection.

Why does negative pressure section drainage require higher foundation height?
The negative pressure section requires a water seal to isolate the pressure difference. The water seal requires a certain height and space. If the foundation is too low, it may not be installed or remain effective.

Can Aili Industrial help check the foundation height?
The foundation and drainage plan can be checked based on the equipment base, drainage outlet and on-site discharge elevation. The specific dimensions need to be confirmed based on on-site conditions.
