Being a green and economic alternative to conventional electric chillers, district cooling systems can provide the buildings in an area with chilled water for comfort and process cooling – hand in hand with district heating. Centralising cooling production has many benefits, including reduced maintenance cost, less space needed for cooling purposes, economies of scale and reduction of the total installed capacity.
What is district cooling?
This short movie introduces what district cooling is and how it can be an integrated component in ensuring a sustainable, carbon neutral energy future. It presents the most frequently posed pros and cons, and through testimonials from customers and sector representatives, an analysis of the big potential for district cooling is shared in straightforward, non-technical language.
Production of district cooling
District cooling can be produced on the basis of an optimal combination of electricity, surplus heat and the best available ambient cooling sources, such as cold water or air. Often, the cooling production is furthermore combined with large cooling storage solutions in order to optimize the production and reduce the need for expensive cooling, while taking fluctuating electricity prices into account.
District cooling services
Ramboll is involved in district cooling projects all over the world, benefiting from 40 years of experience with district energy. Choosing the most optima l cooling solution depends greatly on the surrounding environment. Ramboll’s previous and present projects include many different cooling solutions – ranging from snow-based cooling, through ground source cooling to solar heat-based cooling.
Ramboll provides support in all phases of a district cooling project:
- Identifying the potential: Optimal locations for a district cooling network are mapped
- Studying the feasibility: Estimating profitability and the technical feasibility of the network
- Conceptualizing a solution: Developing an optimal cooling solution
- Finalising the design: Detailing the final design, preparing it for construction
- Following up: Fine tuning the system and expanding the customer base
Mapping profitable district cooling areas
In order to identify the most optimal location of a new district cooling plant within a certain area, Ramboll has developed an automated mapping tool called DCmapper. This tool uses the estimated cooling requirements and geographical location of each building in an area to calculate the economic difference between traditional cooling and a district cooling system.
Ramboll provides 360 degree consultancy within all fields related to district cooling. As we collaborate closely with our departments of district heating, waste-to-energy, combined heat and power, renewable energy and building installations, we are able to offer optimal solutions, including the most efficient use of heating and cooling sources.
