Application Analysis on High Temperature Heat Pump for Waste Heat Recovery of Marine Diesel Engines

In this paper the research status and some key technologies for the ctevetopment anu application of high-temperature heat pump were introduced. The amount of waste heat of marine diesel engine was analyzed, showing the advantages of high temperature heat pump to recover the waste heat from cooling water of cylinder liner in marine diesel engines. Furthermore the conditions for the high-temperature heat pump to recover marine diesel engine waste heat were given, consequently the type of high-temperature heat pump adopted for the marine diesel engine waste heat recovery （WHR） and its system schematic diagram were provided, and the working principle of the system and the difficulties existing in the study were described. Finally two suitable high-temperature working fluids for this system were recommended.
