Abstrakt
Waste heat recovery is one of the crucial and fundamental issue of energy management related with energy efficiency improvement, fuel savings, and reduction of greenhouse gases emissions. The paper provides with the experimentation of the prototype heat recovery system dedicated to the small and mid-sized maritime combustion engines of the nominal load of 100-150 kW. Combustion engine is a primary source for electric energy consumed be all electrical devices in ships and yachts. Conversion of fuel energy into mechanical and electrical energy is related with creation of a significant amount of heat, which is irretrievably removed. Ejection system can be effectively driven by low-grade heat source such as waste heat from the engine. The paper provides with experimental investigations of innovative marine air conditioning unit with application of waste heat for humidity control as well as to driuve the refrigetration system. The results show that such solution can produce 15 kW of cold consuming 70 kW of heat at temperature 120ºC. Cooling capacity of 15 kW should satisfy cooling demand of small- and mid-size yachts.
