According to the last report from the United Nations, more than 54 % of the world's population is now living in cities. Many highly urbanized areas are dealing with the idea of making more with less and the new concept of Smart City is gaining more importance. A smart urban development that integrates advanced information systems and more efficient sources of energy is being consolidated in most of the industrialized countries. The main idea is to mitigate pollution, CO2 emissions, and make overpopulated urban clusters a better place to live in the long term. But how to do more with less? This increasing challenge applies also to the energy sector in cities. Resources are scarce and climate change is being a proven fact. Since the year 1880, the average global temperature on Earth has increased by about 0.8° Celsius, and this phenomenon is highlighted in the cities where thousands of people, cars, factories have to survive facing new challenges that the old solutions have not to be able to resolve. Changing the current paradigm is the most feasible alternative to mitigate climate change and support the cities to reach their ambitious goals in terms of energy consumption. It is in this context that the Centralized District Cooling Plants appeared as an energy-efficient alternative.
A new cooling methodology is needed
Cooling is needed all around the world, especially in cities and the classic individualized alternative consisting of small splits units in each house or office is not very efficient, but it has worked until now. However, to reach the standards imposed by the Smart Cities concept implies going from 0 to 1 using a different methodology and the Centralized District Cooling Plant has been able to reach this goal. The use of a single cooling system that produces energy for a large number of users is much more efficient in terms of energy consumption and conservation. But what if we were able to make DC even more efficient?
Looking for a District Cooling superhero?
ARANER, as the leading company in refrigeration, has been researching for more than 20 years new alternatives to improve the performance of refrigeration plants for different applications, and for the last years, we have applied this big knowledge to DC plants. Our main goal has been to think one step forward about how our technologies can mitigate the problems that still will rise from rapid urbanization such as the increase in global temperature and water scarcity.
What if we could create District Cooling Plants with superpowers? What if we were able to produce cooling for an entire city without consuming water but in a highly efficient way? What if we were able to create more efficient chillers in terms of electrical consumption reducing CO2 emissions? Today, and thanks to the highly specialized engineers form ARANER, District Cooling Plants with superpowers are bec oming a reality. ARANER District Cooling innovative solutions with Remote Integrate Condensation chillers allow us to design plants with zero water consumption and with very similar yearly efficiency as a plant with cooling towers. Also, ARANER District Cooling Plant designs are able to reduce the size of a standard cooling plant in 40 %, which is a great solution for the limited space available in the cities. 
Another advantage of ARANER District Cooling plants is their tailor-made chillers. Instead of standardized units that have to adapt to the project, ARANER designs the chillers for each specific project. Chillers are sized according to the cooling capacity needed, avoiding oversizing and reducing considerably the District Cooling Plant energy consumption around the year. Please, contact ARANER team for more information about how to design the Cooling Plant with superpowers!
