Generating hot water for food processing plant using waste heat, high temperature heat pump and storage.

Number: pap. 1111

Author(s) : KVALSVIK K. H., BANTLE M.

Summary

This paper presents a novel concept to supply hot water to a food processing plant by upgrading surplus heat from a refrigeration system by means of a high temperature heat pump (delivering heat above 100°C). The system utilizes thermal storage and district heat as backup, replacing the currently used electric boilers. Savings for six different system solutions are presented, aiming to find the most sustainable and efficient solution. The savings for the best practice solution were about 41-49% of CO2-emissions, 39-51% of electricity and 29-57% of district heat.
