As a solution, the FDTC and FDT ceiling / cassette units were chosen, in combination with the FDC units of the KX series from Mitsubishi Heavy Industries. The excellent air distribution and quiet operation of the cassette units characterize the installation as a whole. In this way, the correct indoor climate is achieved in a fast, effective and quiet manner. The cassette units are also characterized by an elegant and European design with a clear white panel. In addition, the FTDC unit has won the A’Design Award in 2019.
The setup as described above was created because there may be a varying heat / cold demand between the east and west sides of the building. The 2nd floor does not have this issue and is expected to always have the same heat / cold demand. The 2-pipe VRF system was chosen because of the small available installation space (from 0.36m2!) and divided into an east and west side, so that cooling and heating can be carried out independently.
The outdoor units are selected on the basis of cost, efficiency, applicability and ease of installation. They are set up on the ground floor with the condenser facing the wall, which minimizes any sun exposure, and no noise or vibration can penetrate the property, which is also the safest and easiest way concerning annual maintenance for the service technicians.
Commissioning of the units has been supervised and inspected on site by STULZ, so that the end user is assured that the installation complies with the guidelines set by Mitsubishi Heavy Industries.
After the evaluation with Breuer Klimaattechniek and the client, we concluded the project as satisfied parties. Summers in the office are now cool and comfortable (instead of 30 °C the temperature shows now an average of 25 °C). In this way, staff can work more efficiently in the summer due to the improved conditions in climate and comfort.
