About the products and the project


The project has been recently executed and aimed at replacing old chiller units, to provide the offices of an important financial institution with a more modern HVAC system and superior comfort.

The main aspects in this project were energy efficiency and environmentally friendliness of the system. Customers had a strong attention towards energy consumption. So, what was really needed from their side, was a highly energy efficiency chiller, which could guarantee the cooling capacity needed with very high energy efficiency levels, hence, low operating costs.

This aspect was also guaranteed by Daikin on Site (DoS), which was also included in the package supplied by Daikin.

Daikin On Site is a remote monitoring tool, that can provide 24/7 real time data, all year round, tracking chiller plants operations and their correct functionality. This platform will allow the owners, not only to take preventive actions on the system and avoid extra costs associated with breakdowns and downtime, but also to monitor the energy performance, and be able to make adjustments so the system can be as efficient as possible at all times.

Energy efficiency was also an important to keep the environmental impact of the HVAC system very low. Keeping energy consumptions low, also means keeping CO2 emissions low, and that was very important for the customers, as they have a special attention toward environmental sustainability.

The use of R-32 refrigerant – along with a set of components optimized to efficiently work with it – not only makes the chiller supplied highly efficient, but also makes it a perfectly green solution, thanks to the low GWP (global warming potential) R-32 can offer.

More about the project


As the aspects of energy efficiency and minimized environmental impact were so important,

in addition to the standard options, the EWAT-B- chiller installed was equipped with the full DX Free Cooling option.

With this option the chiller installed will use low external air temperatures to assist in chilling the water used for the air conditioning system. So, whenever outdoor temperatures will be favourable, the chiller will be able to turn off compressors and take advantage of the low outdoor temperature to chill water. That will make the HVAC system even more efficient and green.
