This Wiki-page describes the heat transfer station (connection heat network) of house 2. In contrast to the parent page, which is generalized, this page shows specifically the module of house 2 as it is mounted, prepared and used in the lab at the moment. 

Differences to general CHN module description

Differences between the specific setting in CHN House 2 compared to the general description of a CHN module are:

  • only two temperature levels are prepared and used at the moment
  • there are only two connections to other buildings
  • different ball valves are automated (actuators) - this changes also the IDs
  • pump and control valve on the network side (for feed-in and consumption) are part of the high temperature level instead of the medium temperature level
  • additional ball valve (45)
  • flow meter (5) does not exist in lab, flow values are calculated at another module (DH grid emulator)
