Daikin has recently taken part in an important project involving hospitals in Istanbul, Turkey. It is a government project, aiming at making hospitals more energy efficient through the replacement of chillers and other components of the HVAC system providing these building with cooling or heating.
10x EWAD-TZ Cooling capacity: 7MW
For the KABEV project, Daikin provided 10 screw inverter chillers which will replace old non inverter units in the HVAC systems of 5 hospitals across Istanbul. For this project the consultants performed an energy analysis on the 5 buildings so they could understand how to improve the efficiency levels renovating the HVAC systems. Of course, they performed simulations also making assessments on the return on the investment in case of replacement with Daikin chillers. Of course, being energy efficiency the main goal, inverter technology was fundamental, as it helps adjusting the efforts the chillers make based on the actual cooling demand the building has in specifics moments of the day or of the season.
The screw inverter chillers units from the TZ Series by Daikin were particularly appreciated as they can provide the very high SEER (Seasonal Energy Efficiency Rating) values, which is really what the consultants were looking for. Another important aspect was related to the integrability. As these chillers are being integrated in existing plants, it was important choosing units that could well integrate in the system and be controlled with the existing BMS with the same management and control possibilities as the already existing units.
