Heat recovery in fish meal industry by high temperature hybrid heat pumps.

Number: pap. n. 4

Author(s) : NORDTVEDT S. R.

Summary

The fish meal industry uses large amount of heat for drying, and this paper presents results from a feasibility study of the possibilities for energy recovery by means of a hybrid heat pump. By hybrid heat pump means a vapour compression heat pump with a solution circuit. The working fluid is mixture of ammonia and water which gives many benefits where high temperatures are required and where the heat sink and heat source fluids have large temperature glides. A simulation model was developed to explore the possibilities for heat recovery using hybrid heat pumps, and results from parametric studies with simulation model are presented. The results show that hybrid heat pumps have promising capabilities for use in the fish meal industry.
