District cooling
District cooling is the most environmentally friendly and reliable way to cool the urban buildings while ensuring a healthy indoor climate.
Benefits of district cooling
Environmentally
friendly
Up to 80% less CO2 emissions are produced with district cooling than with local cooling solutions.
Saves
space
District cooling provides an opportunity to free up space previously used by local cooling solutions in the building or its surroundings.
Convenient
and safe
District cooling is silent, suitable for any type of building, and there is no risk of environmentally hazardous refrigerant leakage.
Works in
all weather
District cooling is always available for a client’s specific needs and works even in very hot weather. District cooling increases building’s energy efficiency.
Applications for district cooling
District cooling can be used in all of the cooling systems of a building: for cooling rooms and air ventilation, for precision air conditioners, and also in process cooling. Process cooling can be used for cold warehouses, servers, industrial processes, store cooling systems – for everything that needs to be cooled to seven degrees and above. In the future, the Utilitas district cooling network will cover most of Tallinn’s city center and the Ülemiste area.
Utilitas district cooling systems are awarded with efficient district cooling label
All Utilitas district cooling systems are efficient as per EU Energy Efficiency Directive 2012/27/EU. A district cooling network is efficient if it uses at least 50% renewable energy, 50% waste heat, 75% cogenerated heat, or 50% of a combination of such energy and heat.
Good to know
When calculating the energy label of a building, the use of district cooling gives a 10-fold advantage, since Utilitas’ effective district cooling has a weighting factor of 0.2 compared to a weighting factor of 2 for the use of electricity.
The journey of district cooling to the building
- The water of the district cooling plant is cooled and directed through the pipeline to the cooling substation in the client’s building.
- There, with the help of heat exchangers the cold water cools the ventilation air of the building and water circulating in the cooling system.
- The water that gave up the cold in the cooling process is returned to the district cooling station, where it is cooled again.
In addition to ventilation, district cooling is also used in cooling beams and cooling cassettes.
Joining district cooling
District cooling can be used in business and commercial buildings, as well as new or renovated apartment buildings. Utilitas offers district cooling in Tallinn, and new clients are constantly being added to the rapidly developing district cooling network.
