Booster heat pump transfer stations can be used for heat grids with where the temperature is too low for direct use.
The booster heat pump transfer station in the laboratory consists of a booster heat pump and a direct heat exchanger. It allows the following grid options:
- high temperature district heating grid:
heat can be used directly with the heat exchanger (e.g. with heating grids, where the temperature is high during heating season and low during summer)
cold can be generated with the heat pump (low efficiency)
- low and ultra low temperature district heating grids
heat can be generated with the booster heat pump
cold can be directly used, if the temperature is low enough, or with the booster heat pump - unidirectional / bidirectional operation
an additional pump allows the booster heat pump transfer station to be used in bidirectional grids as well.
