Daikin has recently provided its AHU solutions for an interesting HVAC project, which have been executed I Lanheses, Portugal.

The project included 2 big size Air Handling Units providing an air flow of over 110,000 m³/h, to guarantee that the production facility of an American multinational automotive supplier facility for a big multinational company in the automotive sector, has always the comfort and the air exchange needed.

For this project, the client had to replace the old AHUs installed and decided to go with Daikin, as they already had very positive experiences with the Japanese brand in the past.

For this project were installed 3 very big Air Handling Units. Two 2 of them providing an air flow of 50,000 m3/h each (supply and return), while the third provides an air flow of 13,000 m3/h (supply and return).

The new Digital Control by Daikin was also included in the solutions provided, and there was also an additional customized solution: a small heat wheel for fresh air only (mechanical bypass to the wheel) and mixing chamber.

The Air Handling Units installed are part of the Daikin Professional Series, which is known for being able to offer a tailor-made solution allowing more than 1000 possible combinations. The Series distinguishes for offering highly flexible and customizable air handling unit solutions, suitable for many different applications, and flexibility was exactly what was needed in this project.

The New Digital Control Platform


The AHUs from the Daikin Professional Series provided for this project, also took advantage of the new Daikin Digital Control Platform to meet the needs of this specific project.

The new control solution uses a digital control box that is integrated in each AHU section in order to connect all the sensors and actuators, and then communicate with the DDC Controller mounted on the AHU unit.

All this makes Daikin’s solution unique in the market.

The new Daikin Digital Control solution makes wiring easier and quicker than a traditional solution, thanks to a platform that simplifies the communication between the different sections and devices on a Daikin Professional air handling unit.

That is very important, as the Professional Series is made of modules that usually need to be connected and assembled on site, given the size the units can reach.

While the standard control solutions still helped connecting the different modules and devices on a unit, it posed limits in terms of inputs and outputs, and then in terms of number of modules and devices that could be connected.

The new digital AHU control platform overcomes these limits thanks to a digital box offering up to 310 input and outputs, allowing infinitely expand the possibilities offered by the Professional Series.
