Heat recovery transient simulation of industrial wasted energy through a high temperature heat pump using water vapor as refrigerant
In order to improve industrial energy efficiency,the development of a high temperature heat pump using water vapor as refrigerant is investigated.Technical problems restraining the feasibility of this industrial heat pump are surmounted by a specifically designed heat pump and the development of a new twin screw compressor.This article presents the development of a new dynamic model of this heat pump using flash evaporation.A finite-volume(FV)approach is used for the heat exchangers models while a moving boundary(MB)approach between phases is implemented for the flash evaporation system model.The mechanical inertia of the fluid was taken into account by writing the transient balance equation of momentum in the heat exchangers.The study shows the evolution of the internal heat pump parameters in function of external sources disturbances in order to improve management strategies of this energy sources.The models are developed using Modelica as a modeling language without any library involvement and taking into account as many details as possible to closely represent the real system.
