FläktGroup is one of the world’s largest supplier of products and solutions related to indoor climate control. The Jönköping location is the largest production facility for FläktGroup. Air handling equipment for commercial buildings are the company's major products, while ventilation and air treatment are its primary business. An air handling unit is used to continually exchange indoor air for outdoor air in order to accomplish the desired air exchange in a structure. The air handling unit is used to heat, chill, and filter incoming air in addition to using fans to move air into and out of the building and exchange heat between incoming and exiting air.

To further increase the lifecycle of the current fan-walls. FläktGroup had a study done by a student to see if it was possible to decrease the vibrations on the fan-wall. Since a decrease in vibrations will results less stress on the bearings and increase the lifecycle. Which in turn means that the product needs to be replaced less often and have less maintenance done.

The study will be following FläktGroups steps for a product development. The overall project can be divided in the following steps: 1. Project definition – 2. Concept generation – 3. First selection of candidate concepts – 4. CAD design of candidate concept(s) – 5. Prototype build –6. Verification in lab – 7. Conclusion. The study will mainly focus on step 2-7.

Due to the complexity of the study, it will have a experimental approach, which means that no calculations will be done and everything will be done by experimenting and verifications through data collection software.

The main focus to reduce vibration on the air handling unit was to modify and improve upon existing fan-walls, either to stiffen it or cushion it. The theory used for this was a simple vibration formula that contained the correlation of stiffness, mass, and damping.

Through the process given by FläktGroup three main concepts were chosen as candidates to further test on and finally one concept was picked to pursue. A horizontal beam that reduced vibrations considerably. A concept that showed extra potential was also found, however not enough testing was done and is encouraged to be tested more upon in the future.
