AN EFFICIENT HEAT PUMP-BASED HEATING SYSTEM WITH HEAT RECOVERY

The invention relates to a heating system comprising a heat pump system. The heat pump system comprises a heat pump, operating with a primary fluid, and a secondary fluid. The heat pump system further comprises a first sink heater. The heat pump is connected to the first sink heater, and the first sink heater is configured to preheat a process medium. The heating system further comprises a second sink heater configured to transfer heat to a second process medium. The heat pump system further comprises a heat exchanger that is connected to the second sink heater and is configured to transfer heat from an exhaust medium of the second sink heater to the secondary fluid used to provide heating to the process medium. The heat pump is connected to the heat exchanger in a parallel configuration. Furthermore, a method for integrating a heating system into a drying plant, the heating system comprising a heat pump system, is provided.
