Design of Supercritical CO² Jointing Solar Thermal Refrigeration System with Utilization of Ship Waste Heat

Abstract

Abstract.In view of the current shipping industry is facing energy waste, environmental pollution and other issues, energy-saving and emission reduction are imminent. As combined the characteristics of high temperature waste heat produced by marine engine and other equipment on ship with solar thermal system, using supercritical CO 2 (s-CO 2 ) Brayton cycle to design a marine refrigeration cycle system. And analyzing the whole refrigeration system, verifying the feasibility of the system on board applications and it is able to meet the board requirements. Finally, an automatic control method is proposed to automate the entire waste heat refrigeration system in any environment.
