Booster heat pumps and central heat pumps in district heating
Applied Energy, 2016Abstract District heating (DH) enables the utilisation and distribution of heating from sources unfeasible for stand-alone applications and combined with cogeneration of heat and power (CHP), has been the cornerstone of Denmark’s realisation of a steady national primary energy supply over the last four decades.

If the flow of refrigerant in a cooling system is reversed, the heat exchanger which was the evaporator becomes the condenser and vice versa and the flow of energy is reversed. Reversing valves may be fitted to cooling circuits in order to divert hot gas for defrosting the evaporator or to provide heat in winter to a conditioned space.
