Flexible heat pumps with integrated latent heat storage

  • a) Solutions for the use of latent heat storages in heat pumps are developed and tested in order to use available electricity at low cost for heat generation and to supply this heat to the building with a time delay. The power supply from the grid to drive the heat pump/chiller is based on the supply situation, which is dominated by fluctuating feed-in from renewable sources. The useful energy provided is stored in the form of heat or cold.
  • b) develop and test concepts for the use of electrical and thermal storage in cooperation with Finnish partners. For this purpose, a pilot plant will be constructed and operated at the TAMK University of Applied Sciences in Tampere in which, in addition to various heat sources, electric battery storage units and a heat pump with integrated latent heat storage unit will also be tested. The development of this heat pump with heat storage is the subject of the project described here.
