Surely having the input fluid being colder is a benefit, not a problem? Just run the fluid more slowly through the system?
- matt-p 3mo agoIn essence you can't really because slower flow rate makes the heat transfer less efficient. You'd be halfing the flow rate in that example.
- gooseh 3mo agoBut a larger delta-T makes it more efficient?

- dist-epoch 3mo agoMaybe you can use a heat exchanger, like in nuclear power plants, and separate the data center flow from the outside flow, so they can go at different speeds.
- matt-p 3mo agoYou would use a heat exchanger normally anyway. Forcing the outside (DH) to be slow would get you that, but there is cost in having low flow in that HXs are less efficient at the far end and you can transfer less heat in the same pipework (it would more than half the district heating capacity). So in practice, not really.
