UBS ELIT Restaurant, Zurich
Cooling was realised with the R-744 (CO2) refrigerant, and the existing distribution network remains in use with some of the relevant components such as pumps and condensers replaced. The waste heat of the commercial cooling system is used for domestic hot water.
Rice Up!, Zurich Main Station
Realisation of a compact system for restricted spatial conditions that is nonetheless state-of-the-art in terms of technology and safety. The system was integrated into the recooling network of the main station.
Limmatplatz Migros, Zurich
Connection of cooling units with high evaporation temperatures to a central commercial cooling system that has been designed for the highest energy efficiency in this area of use.
Illuster Migros, Uster
Connection of cooling units with high evaporation temperatures to a central commercial cooling system that has been designed for the highest energy efficiency in this area of use.
Mall of Switzerland Migros, Ebikon
The cooling system was designed as a transcritical CO2 booster with parallel condenser and inverted heat exchanger for the heat pump function. The cooling units are dewatered via a vacuum system.
Migros, Sirnach
The commercial cooling system for the chilled and refrigerated sections uses the R744 (CO2) refrigerant. The waste heat is used for the warm water pump heating system.
St. Fiden Migros, St. Gallen
Cooling units with high evaporation temperatures were connected to the central commercial cooling system. To increase efficiency, the “plus” cooling level of the R-744 (CO2) plant was equipped with a parallel condenser.
Dübendorf Hochbord, QM Mandate
Heat production and domestic water treatment with multiple heat pumps. Geothermal probe fields are the energy source.
Frequency Converter Waste Heat Utilisation, SBB Opfikon
There are two large SBB frequency converters in Opfikon that each produce 2.5 MW in waste heat. From the heat extraction, a district network is connected to the nearby residential blocks that are being heated with the waste heat produced by the frequency converters.
Indoor Pool and Ice Rink, Zurich-Oerlikon
The district heat consumption of the indoor pool in Oerlikon was reduced by integrating a new heat pump into the existing hydraulic network. The waste heat generated in the production of the ice for the ice rink is used as an energy source.
Lake Water, Bregenz
Development of an overall energy concept: lake water for the site’s air conditioning and as an energy source for the heat pumps that heat the site.
Superblock, Winterthur
Overall planning for various cooling and free cooling solutions as well as development of a safety plan. The project includes ammonia cooling units and hybrid recoolers that can be used for free-cooling purposes on colder days.
Denner Distribution Centres, Lyss and Dietlikon
The existing ventilation distribution network was replaced with large recirculation coolers. The result: a reduction in primary energy consumption of more than 70 per cent. The renovation took place while the facility was in full operation.
Lonza Arena, Visp
New ice rink hall with transcritical CO2 system for ice rink cooling, air conditioning, dehumidifying, and heating with a heat pump system. Lonza AG’s Rhone river-water system and the local deep water act as both an energy source and re-cooling system.
Ice Rink, Wallisellen
Renovation of Winter World Wallisellen with feasibility study for roof and hall, and replacement of the existing technical facilities as well as new construction of both ice fields.
Tägi Ice Rink, Wettingen
A two-stage ammonia plant is cooling the two ice fields (one of which is covered) and acts as a hub for the heating energy supply at three different temperature levels across the centre. Energy compensation occurs through the centre’s own groundwater system.
Ice Rink, Sissach
Total renovation of the technical facilities after fifty years, along with climate conditioning of the ice rink.
Malley Sport Centre, Lausanne
The project included the construction of three ice rinks, an aquatic centre, a fencing centre, a swimming pool, and a table tennis centre.
Ice Rink, Aarau
The cooling system was completely replaced, the indoor ice rink and the curling field were newly fitted, and the outdoor rink was replaced with a new, covered ice rink.
Heuried Sport Centre, Zurich
Installation with two transcritical CO2 systems. In a single-stage transcritical process, energy from the ice fields is transmitted to the heating systems in the form of waste heat.
