Large Industrial Heat Pump installations with natural refrigerants benefitting semi-welded plate heat exchangers

The presentation will describe cases of large industrial R-717 Pump installations showing how waste heat can be recovered from a various source.
They have been operating efficiently since a few years with semi-welded plate heat exchangers.

Description

The main case of heat recovery is from a data center which has been in operation a few years. The construction of the new data center in Denmark starting in 2017, was determined to be one of the most advanced, energy-efficient data centers in the world.
The new facility features the latest hyper efficient hardware, cooled using outdoor air through indirect evaporative cooling technology and powered by clean and renewable wind energy. The facility is unique because of the infrastructure to capture and recycle the excess heat generated by the servers to provide heat to the local community. The heated air from cooling the servers flows via water coils, recovering the heat by raising the temperature of the water. This water is then supplied to a newly constructed Heat Pump installation where the temperature is raised further and delivered to the district heating network and distributed to the local community.
Sector coupling was made possible by a partnership with the local district heating company. They were looking for new heat sources to phase out fossil fuels for the district heating of the city. A partnership was initiated. The local district heating company made the additional Heat Pump investment to recover the waste heat and will operate a new built Heat Pump station. A pipeline of cooling water circulating between the data centre and the Heat Pump station was established. The data centre proximity to the local heat distribution grid did minimize additional infrastructure connecting the heat pumps to the district heating network. The impact of the facility’s heat recovery infrastructure will help recover 100,000 MWh of energy per year – enough to warm some 7,000 homes. The Heat Pump installations are made in three sections each supplying about a third of the total heat to deliver. IES Energy Aps was delivering the Heat Pumps and Alfa Laval was supplying the evaporators, condensers, oil coolers sub coolers to the Heat Pumps.
This case and possible some other will be presented more in detail during this session.
