With the new legislative measures that impose limits on the use of F-gases, and with a rapidly developing urbanization, the HVAC sector – today more than ever – requires a real transition towards increasingly efficient solutions with minimal environmental impact (outdoor), while achieving the required conditions in compliance with environmental standards (indoor).

A new generation of refrigerants is therefore needed. The recent development related to HFO refrigerants is becoming more and more a reality in the world of HVAC systems. The low GWP values of these refrigerants and their operating characteristics make them compatible with the air conditioning systems on the market today: unlike natural refrigerants, HFOs and their blends with HFCs offer the possibility of retrofitting systems already installed.

The 5 star VICTORIA-JUNGFRAU Grand Hotel & Spa, located amid the mountains of the Bernese Highlands – overlooking the Jungfrau, maintains its leading status in the luxury hotel sector for more than 150 years. During the Belle Époque, royals, intellectuals, artists and authors from around flocked to stay at this luxury hotel. Today, a new conference zone and VICTORIA-JUNGFRAU Spa set new standards in the international hotel scene thanks to its size and the extensiveness of its range.

By combining reliability, design and high performance of Tecnofreddo products with the use of a very low GWP refrigerant, the water-cooled liquid cooler – optimized for R1234ze- has been the best choice for the VICTORIA-JUNGFRAU Grand Hotel & Spa for which high comfort, reduced management costs and low ecological impact are essential for the indoor well-being and for a more sustainable future.

The coordination of this project was carried out by an important Swiss partner of Tecnofreddo, Bouygues Energies & Services. With its approximately 5000 employees in over 90 locations throughout Switzerland, Bouygues Energies & Services is the number one company in building technologies and facility management, having the necessary know-how and expertise to offer its customers complex and cutting-edge technologies.

Tecnofreddo and Bouygues Energies & Services (Switzerland), a perfect partnership to combine innovation with respect for the environment.

The Tecnofreddo water-cooled liquid cooler operates with the latest generation ecological refrigerant HFO-R1234ze. With extremely high energy efficiency (COP ~ 4), the chiller was manufactured with 2 Frascold screw compressors, with a cooling capacity of about 700 kW for cooling water at a temperature of 10 ° C. The chiller also includes a control panel with programmable software (PLC), designed and programmed by TECNOFREDDO. The chiller has been designed in line with Sia standards, and the corresponding European standards.

Sustainability and technology, environment and innovation, a winning combination for the planet. An eco-innovation that contributes to significant progress towards the common goal of sustainable development, signed Tecnofreddo and Bouygues Energies & Services.
