Providing efficient solutions within a refurbishment project involving a hospital

Daikin has recently supplied chillers within a refurbishing project involving a Spanish hospital. The project has been carried out in the context of a program, aiming at improving the energy efficiency of the building and minimize its environmental impact.

Total cooling capacity: 4MW

 

About the products and the project

 

For this project Daikin provided 3 screw inverter chillers, two water-cooled chillers and one air-cooled chiller. They will replace old non inverter units in the HVAC system of the Spanish hospital. Thanks to the installation of more advanced technology, Daikin managed to meet the efficiency targets, helping achieve energy savings, reducing operating costs, and cutting CO2 emissions by 25%.

To achieve these goals, the project required an environmentally friendly HVAC concept. That is why it was decided to use chillers featuring the HFO refrigerant R-1234ze. This refrigerant set the new standard for environmentally friendly cooling systems, with a GWP (Global Warming Potential) 200 times lower than R-134a. R-1234ze refrigerant paired up with Daikin’s Single Screw compressors technology, ensured that the energy efficiency targets were met.

More about the project

 

Besides energy efficiency, reliability was another very important aspect as chillers are supposed to provide cooling also for laboratories and technical equipment. So, having a reliable solution was fundamental to ensure that both the comfort and the process cooling needs of the hospital were met.

The screw inverter technology by Daikin definitely helped with reliability. Daikin has a history of leadership in the field of single screw compressor chillers, which have been installed all over the world for 20 years.

Daikin screw compressor, differently from a standard screw compressor, uses one main screw meshing with twin star rotors to produce volume matching compression cycle. Due to the main rotor, balanced in both radial and axial direction, the compressor bearing has extremely high reliability. Therefore, its life span can be longer than other screw compressors. The single screw compressor, then, has only three moving parts. As a result of that, it reduces the possibility of failure and keeps operation costs low.
