R-32 chillers for a hotel in Portugal

Daikin has supplied an air-cooled scroll chiller with R-32 from the EWAT-B- Series, so the clients’ needs in terms of energy efficiency, enviromental sustainabilitity and reliability could be met.


With this project Daikin supplied two R-32 EWAT-B- chillers in a Hotel in Porto, Portugal. The two units were installed as a replacement of two old chillers which were no longer able to meet the needs of the hotel both in terms of reliability and energy efficiency.

The two R-32 chillers by Daikin have been recently installed to provide chilled water to fan coils placed in the whole facility.

The two units have been chosen to replace the old ones with more reliable chillers, as the old ones could not properly meet the needs of the facility, forcing the client to constantly face insufficient cooling issues.

Most importantly, Daikin had to offer more efficient chillers than the ones previously installed, also increasing the sustainability of the HVAC plant serving the hotel.


HVAC systems for hotels are typically required to create the best possible comfort for guests with reliable and efficient technologies.

Customer experience is a priority for any hotel, and that should be no surprise as customer experience is what the hospitality industry is all about.

Daikin as a brand, of course is globally recognized as a brand of great reliability, no matter the chiller type. But reliability was not the only aspect in the project.

Sustainability, for instance, was ensured with units from the Bluevolution Series, a line of products featuring the low GWP (675) R-32 refrigerant, which not only is a sustainable refrigerant for the inherent chemical characteristics, but also guarantees very high energy efficiency levels when used in a thoroughly optimized chiller design.

The EWAT-B chiller in fact, stands out for providing the great efficiency levels and very low direct and indirect CO2 emission levels, which makes the EWAT-B-Chiller a great environmentally friendly choice.
