Daikin solution for a complex of office buildings
Daikin has recently provided its HVAC solutions for another great office building project, this time in Krakow, Poland.
The above-mentioned project involves a complex of five buildings providing modern office space in the very center of Krakow. The office complex offers about 70,000 sqm of leasable working space for businesses. The project started 3 and a half years ago when the buildings D and E were delivered. The buildings A and B have been recently completed, while the building C will be completed in the next few days.
About the project
The pieces of equipment described above will be used to guaranteeing that the requirements in terms of comfort are constantly met throughout the year, giving the employees of the companies that will take advantage of these impressive office buildings the best possible working environment.
All the buildings were provided with Air-Cooled Screw Inverter units by Daikin, while the VZ range was used where the project posed space issues.

Among the main aspect for this big project there was definitely energy efficiency.
The level of efficiency a chiller can deliver clearly have an impact on energy consumptions and running costs related to the office building. And it was customers’ interest to install technology that could help keeping energy consumption as low as possible.
This is why Daikin Screw Inverter units were installed in every building.
The Inverter technology continuously modulates the speed of the compressor’s motor, which is the most efficient way to perform the capacity control of the compressor. In this way, Variable Frequency Drive provides chillers with outstanding part load or seasonal efficiencies, also allowing great energy saving opportunities.

To make the HVAC system even more efficient, it was important to make sure chillers could also vary the water flow depending on the actual load demand of the building. So, variable water flow in the primary circuit was provided. This option will make pumps more efficient, modulating the quantity of water flowing through the system, thus reducing pumps impact on energy consumptions.
Reliability, then, was another important aspect. This is another reason why screw compressors units were chosen, as Daikin in-house developed screw compressors can guarantee a life span longer than other screw compressors.

Another interesting aspect was the fact that the chillers needed to work on pure water (without glycol) for this project, which is not exactly a standard request considering the ambient conditions in Krakow. But Daikin managed to meet this need as well.
