Virtual Heating Plants

| 2021:816 | Erik Lundmark, Mattias Vesterlund
Data centers can replace existing heating plants in a district heating system if the right cooling technology is used and IT hardware can achieve the same power intensity. A testbed has been created to support the technological development of liquid-cooled data centers. The goal is to be able to create excess heat that does not need heat pumps to be used in a district heating network.

The project aims to demonstrate the opportunities and obstacles that exist to switch from air cooling to liquid cooling of data centers, with it being able to allow data centers to constitute as virtual heating plant in the district heating system.

To enhance the use of liquid cooling in data centers for heat recovery the biggest obstacles are; the additional cost for more expensive technology, knowledge of the properties of the technology, lack of cooperation models, and division of ownership responsibility between the data center owner and the recipient of the surplus heat.
