Abstract: 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.

Abstract: The invention relates to a drying system (1) comprising a drying plant (2) and a heat pump assembly (3) comprising one or more heat pumps operating with a primary fluid and being connected to at least two heat sources and at least one heat sink by means of a number of heat exchangers in a fluid network, in which a secondary fluid circulates. The heat sources may comprise dew point dehumidification in at least one heat exchanger (41) of process gas entering the drying plant; and recovery in another heat exchanger (42) of latent and/or sensible heat from exhaust gas leaving the drying plant. The heat sink may comprise pre-heating in a heat exchanger (51) of process gas used within the plant. Further, a method of integrating a heat pump assembly into a drying system is devised. By the invention, it is possible to increase the capacity of the drying plant while reducing the specific energy demand.
