I - AIR HANDLING UNITS (I-AHU)

I-AHU is web based selection software for air handling units design and selection, with optional module for the production. 

​

Main features:

​

  • Web Based software (no installation process)

​

  • Cloud server

​

  • Supports process from offer till order

​

  • Technical calculation

​

  • Price list

​

  • Datasheet (multi brands)

​

  • Integration of  DLL’s (fans, coils, etc.)

​

  • Full customization (rules, data, 3D parts)

​

  • Energetic Analysis

SHIPPING COST ESTIMATION


Considering the volume of an air handling unit, where in a lot of cases you are shipping empty boxes, we can offer our custom procedure which allows simulation of different shipping scenarios.
This means either to ship the unit assembled or in pieces considering following factors:

  • complete AHU assembly volume

  • precise dimensions of all disassembled parts

  • assembly cost at factory and delivery location

  • transportation cost per truck size

  • rules which parts can be packed together

  • additional costs (customs, forklifts, etc.)

  • detailed assembly instructions. The user has the possibility to make fast or precise calculation.

Fast calculation is based on default input and calculation data. It enables final calculation without the need of any intermediate calculations where the user receives an optimized AHU.
Precise calculation allows the user to edit immediately each section separately, and to have a full control of the complete selection process.


ENERGETIC ANALYSIS
IDEA is specialized in the HVAC businesses, with years of experience working on specific Energetic analysis calculations. Therefore, our I-AHU WEB can be extended to calculate the unit price based on different energetic analysis costs.


ENERGY CLASS OPTIMIZATION
The software allows optimization of the components (filter, coils, fans, heat recovery) to obtain the energetic class required by the user. The calculation process will suggest changes to the user till it meets the required energy class. During the 'software loop for optimization' several optimization points are possible, where the software can be set up in order to define the optimization priority (size, coils, fans, etc.).
 

EUROVENT REQUIREMENTS
Upon request, we are also able to provide full certification support. Our support consists of one person who is dedicated to Customers and who manages the complete certification process. During this period, he would be like "your employee", acting to protect all the interests of your company and to plan for everything to be completed on time and within the budget.

​

ErP - TIGHTENED EFFICIENCY REQUIREIMENTS
I-AHU WEB evaluates the designed unit performance according to the ErP normative. A detailed report is generated in order to give additional information for which Stage (2016, 2018) the unit is certified.

​

​

I-AHU 3D PRO


I-AHU 3D PRO is the air handling unit production module, specially designed as an extension of I-AHU WEB selection software.


Main features:

  • supported by professional CAD software

  • connected to l-AHU WEB

  • process from order till production

  • automatic production documentation

  • automatic 3D assembly

  • no limitation regarding unit sizes

  • integration with in-house ERP

  • customized (rules, data, 30 parts)

  • same WEB user management

SOFTWARE STRUCTURE
I-AHU 3D PRO is not limited to generate only database defined unit sizes, but can allow full customization because it's 3D assembly has a parametric structure and NEW FILTER OPTIMISATION DLL.

​

DATASHEETS
The drawings are automatically made, and can be further edited by an authorized user. Any change made to the automatic generated 3D assembly will affect also the drawings, and refresh including new updates. The user can control which parts he would like to export and in which format. The standard is to give pdf files for bending and assembly documentation and dxf files for the sheet metal processing. Documentation for cutting lists, BOM and part is available.
Nesting module for profile cutting optimization can be applied in order to lower material waste.

TYPE OF CALCULATION
The user has the possibility to make fast and precise calculation. Fast calculation is based on default input and calculation data. It enables final calculation without the need of any intermediate calculations where the user receives an optimized AHU. Precise calculation allows the users to edit immediately each section separately, and to have a full control of the complete selection process.


FILTER
I-AHU optimize the size of units in function of standard filter dimensions and air flow. User receives different solutions with different ratio of height / width and different air speed. This approach allows user non standard AHU which will fit the installation space.


FANS
I-AHU use the dll of the main european producers, where it can also be customized to use specific dll, required by the producer. As alternative it is possible to introduce our own dll.

​

COILS
Coils are calculated with our dll, where it is possible to add tools for the production like circuitation, header drawings, etc.
This approach allow to speed up the purchasing process, by giving to the producer exact needed coil dimensions.
Implementation of other supplier dll's is possible.

​

HEAT RECOVERY
I-AHU includes cross flow and rotary heat recovery. It is also possible to select twin coils systems using our dll for coils.


DAMPER
Damper can selected from a database of standard sizes, or in function of the rules given by the producer.

Calculation process

​

1. User chooses the configuration of AHU as a unit composed by sections positioned on one or two levels. The configuration is defined as one air treatment schema, and can be saved for future usage. It is also possible to define configurations with sections of heat recovery.

2. Based on the requested air flow and air speed (tolerance), the software highlights the range of units suitable for the request considering predefined filter sizes from the database. This approach allows the user to have more solutions than just catalogue sizes.

User sets temperature and relative humidity of the internal, external and immission air. The definition of the percentage of fresh air allows the software to automatically calculate mixtures of air entering to heat exchangers.

3. The characteristic of the structure can be set through the definition of profiles, panels, materials and omegas.
4. After inserting the standard definitions, the program displays graphically the unit and allows you to define the characteristics of individual sections, size the dampers and heat exchangers (finned coils and heat recovery), fans, motors and transmissions, as a function of the operating conditions indicated in point 2. Different supplier dll's are integrated in the software

5. The humidification system can be selected according to the efficiency calculated. An option that allows the automatic selection of fast calculation of all the components of the AHU can be done referring to the default values set by the user.
6. The user can edit the unit by adding, changing or deleting any section.

7. A print-out of the technical data including detailed diagrams of the air processing and the chart of the fans with an indication of the operating point is available. Dimensional drawing of complete configured unit is included.

8. The software allows to print economic offers with the total price of the unit and/or detail of the individual sections and accessories or dimensional drawing.
