Sustainable process heat supply by a high-temperature heat pump utilizing waste heat from a chiller

•Sustainable process heat supply via a
high-temperature heat pump (HTHP) by waste heat utilization from an existing chiller

•First step: Supply of a Cleaning-in-Place (CIP) system

•Next steps: Integration of further consumers (e.g. warm water, pasteurization, …)

•Reduction of the waste heat rejected to the ambient and the electrical demand of the ambient air cooler

•Direct integration of a HTHP into an existing chiller for waste heat recovery

•Use of a natural refrigerant (ammonia, NH3)
