Collaboration MP3-ENERGO

Union is strength!

In its research and development sector, MP3 has started from about one year an innovative line of research to obtain and publish the technical data for the selection of its own products.

Number one in Italy and possibly the World, MP3 has chosen to develop in collaboration with ENERGO a method of analysis for the eraulic behaviour of products of diffusion with the use of a series of integrated CFD programs. On the basis of the principle of the finished elements, allows to create mathematical models apt to perfectly describe the air motion in any condition and to provide information on the speed, pressure and temperature of the air in every point of the room, inside diffusers, ducts and all those units that make up a full air treatment system.

In this grand development plan the union has been reached between two big experts in the field of air treatment.

 

MP3, and its young dynamic technical and commercial staff, has been able to acquire large segments of the market through its strong points: the first being the best possible service to the customer, in terms of the commercial and technical stand points, providing the most amount of information on performance data and carrying out a constant in-depth re-examination and improvement of current technical documentation. All this to answer, in a comprehensive manner, questions and requirements of installers and project managers.


Linear diffusers KL Series

The simulations made with the CFD, position MP3 in clear advantage in the market, allowing to supply vastly more precise and accurate fluid dynamic data compared to that acquired through the use of traditional test rooms. The analysis obtained with the use of the CFD program also forms a very useful support during the planning stages. It allows to carry out fluid dynamic studies prior to the production of prototypes and implementation of production lines. In so doing, it allows to proceed with the production of new products only once the perfect optimisation of the unit has been confirmed. 

Finally, the decision to use simulations with CFD, integrates the considerable commitment that MP3 has undertaken in these past years in the area of noise analysis by carrying-out numerous test and evaluations at prestigious international laboratories.
 

For over five years now, the ENERGO agency uses advance CFD simulation technologies, to supply manufactures, architects and other project planning agencies, complete and reliable solutions able to give an immediate evaluation from a fluid dynamic point of view of the product, the environment or building.

As a result of the “visualisation” of the thermo fluid dynamics, these analysis allow an immediate determination of the performances of a prototype, both virtual and realistic therefore allowing the development and optimisation of products prior to their construction, minimising the need for modifications once production has begun or the evaluation and remodelling of existing product designs. Furthermore, through the use of CFD technologies, used in the planning of HVAC systems, reveals itself to be more efficient and flexible compared to the sole use of traditional methods. This because it allows to give a highly reliable forecast on the behaviour of the system (even in different scenarios or where variations occur at the same time) and the degree of comfort achievable.

This approach, therefore, allows to make the most appropriate choices and make all the necessary optimisations to systems while still at the planning stages as a guaranty of improved realisation and with clear savings on time and costs.

A virtual test room

Get the Flash Player to see this player.
The use of the integrated CFD programs allows to simulate the distribution of the speed of air injected from the diffusers inside a room of any size and shape.

What is particularly interesting is the study on a surface section placed at a increasing distance from the diffuser.

The traditional test rooms, other than having fixed dimensions, allow to measure the air speed only in limited points, whereas with the virtual test room, it is like there are an infinite umber of sensors.

It is also possible to simulate heat sources, heat dispersion areas, furniture and any other variable that may influence the flow or air.

Studying the unknown aspects

The use of the integrated CFD programs allow to verify the distribution of the air speed inside the plenum of the diffuser, therefore identifying the optimal dimensions for a homogeneous and perfect exit speed from the diffuser taking over from the traditional empiric and rough methods in favour of a reproducible method, both quick and precise.

Speed vector analysis

The use of the integrated CFD programs also allow the vector analysis of the speed, allowing therefore to define the direction of air in movement, simulating an infinite number of 360° sensors in the test room.

This analysis is fundamental when there are more diffusers in the same room and it is the only one that allows to exactly describe the condition created from the intersection

 

Inside the diffuser

The study of air speed distribution inside the diffusers is fundamental to identify the apt solutions in reducing noise and pressure losses.

The use of the integrated CFS programs allow to analyse the flow of air in any shape of duct and therefore inside also the diffusers. This makes it possible to optimize any new project and compare accurately alternative solutions.


Circular diffusers KU5-6-8 Series

It also allows to exactly determine the air speed on exit, normally indicated with Vk, as well as the efficient section on exit normally indicate with Ak.
The exact knowledge of these values will allow the installer to perfectly calibrate the diffusers and of the system in its entirety.

Not only diffusers

The integrated CFD programs form an optimum support when planning any type of eraulic components. The ideal example is the that now reaching the final stages, the new WK series European fire damper, EN 1366-2 approved.

Only with an instrument like the integrated CFD programs is it possible to know the exact effect of the flow of air of the obstacles inside the duct, like the damper blade, the mechanic stopper and the thermal fuse.

This has allowed to manufacture a product that not only responds to the high fire resistance requirements indicated by the standard but also one that can guarantee the optimisation of the pressure losses and the maximum reduction of the generated noise.


Analysis of any environment

The integrated CFD programs allow to build diffuser models in any type of environment. The collaboration between MP3 and ENERGO, can therefore produce personalised studies simulating the exact installation environment of the products while at the same time taking into account of any type of necessary variable like the arrangement of the extraction points, furniture layout, presence of heat sources, heat conduction of glass surfaces and seasonal changes.

This study in infinitely more precise in comparison to what can be obtained from the common selection programs provided by the different manufacturing companies as it does not pose any constraints in defining the environment and does not draw on archives results more or less developed from standard findings. On the contrary, it calculates, for each case, the behaviour of the air on the basis of the physical laws of fluid and thermal dynamics.
